<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the [http://en.wikipedia.org/wiki/UNICOM UNICOM] frequency is used by the pilots use to talk to each other, usually 122.700, 122.800, 122.900, 123.000 or 123.050. Airports with control towers usually have an assigned Unicom channel of 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS ([http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#ATIS Automatic Terminal Information Service])- Weather, equipment failures, closed runways and taxiways, current operating runways, special notes, and NOTAM's.<br />
# [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#Clearance Clearance Delivery] - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#Ground Ground Control] - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#Tower Tower] - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a TRACON[http://wiki.radioreference.com/index.php/TRACON (Terminal Radar Approach Control)] or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC Center] (Air Route Traffic Control Centers), commonly called [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#AirTrafficControl Air Traffic Control]). <br />
#Approach Control([http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />

== Company Airlines Operational Control ==<br />
When aircraft are within 20-30 minutes of their destination, they call in on freq's 128.825 - 132.000 and 136.500 - 136.975 to report equipment malfunctions, delays, rerouting, and the special needs, such as wheelchairs and un-accompanied minors(UM). Sometimes, when they are about 10 minutes off the ground on their trip away from the airport, they call back with the times they were off the gate, and off the ground. However, [http://wiki.radioreference.com/index.php/ACARS ACARS] has replaced some of these communications.<br />
<br />
On the ground, there may also be company frequencies in the 460.675 - 460.900 range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 freq’s before it is announced. These are NOT listed at [http://www.airnav.com/airports/ AirNav]. <br />
<br />
You can also find other air-related frequencies used around a major airport by doing a Geo Search for the Lat/Lon of your airport. Go to:<br />
<BLOCKQUOTE><br />
* [http://wireless2.fcc.gov/UlsApp/UlsSearch/searchGeographic.jsp FCC Geographic Search]<br />
* Enter the Lat/Lon of the airport (from AirNav)<br />
* Enter radius of 1 Kilometer<br />
* Hit the search.<br />
</BLOCKQUOTE><br />
<br />
== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware] will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, and tracking if still enroute.<br />
<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br><br />

</blockquote><br />
<br />
== Google Earth 3D tracking ==<br />
With Google Earth installed on your PC, you can not only track one or several flights, but you can “rotate” the view when a plane is near an airport and see it actually descending or climbing. This is really neat! Download [http://earth.google.com/download-earth.html Google Earth] free.<br />
Then go to [http://www.fboweb.com/antest/ge/intro.aspx?old=1 FBOWeb General Apps] or <br />
[http://www.fboweb.com/fb40/s/tr/qt.aspx?ss=1 FBOWeb Specific Flights]<br />
<br />
Enter airline flight info, and click on the “Track in 3D” button. It will “install” the specific flight <br />
as a layer on Google Earth, and will also track aircraft in the general vicinity.<br />
== Identifying Frequency vs. Airport ==<br />
When searching or monitoring the airport specific frequencies, such as Aproach/Departure, Clearance Delivery, Tower, ATIS, etc you can usually find out what airport you are hearing by typing '''airnav freq state''', into a Google search box.<br />
I.E. '''airnav 128.7 Pennsylvania'''<br />
<br />
== Notes ==<br />
# 121.500 (guard) is used far more often to communicate with aircraft that have somehow strayed onto the wrong frequency, and ATC cannot get hold of them on their assigned frequency. If they are listening on 121.5 the controller will probably be able to get through to them and get them back on the correct frequency. The monitoring of the 121.5 & 243 frequency via satellite will be eliminated in 2009. Apparently, 'they' are going to the 406 MHz satellite monitoring only. 406 MHz uses some digital encoding when broadcasting that can give aircraft details as well as GPS coordinates.<br />

# 121.500 (guard) is used far more often to communicate with aircraft that have somehow strayed onto the wrong frequency, and ATC cannot get hold of them on their assigned frequency. If they are listening on 121.5 the controller will probably be able to get through to them and get them back on the correct frequency. The monitoring of the 121.5 & 243 frequency via satellite will be eliminated in 2009.

<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the [http://en.wikipedia.org/wiki/UNICOM UNICOM] frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS ([http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#ATIS Automatic Terminal Information Service])- Weather, equipment failures, closed runways and taxiways, current operating runways, special notes, and NOTAM's.<br />
# [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#Clearance Clearance Delivery] - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#Ground Ground Control] - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#Tower Tower] - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a TRACON[http://wiki.radioreference.com/index.php/TRACON (Terminal Radar Approach Control)] or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC Center] (Air Route Traffic Control Centers), commonly called [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#AirTrafficControl Air Traffic Control]). <br />
#Approach Control([http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />

When aircraft are within 20-30 minutes of their destination, they call in on freq's 128.825 - 132.000 and 136.500 - 136.975 to report equipment malfunctions, delays, rerouting, and the special needs, such as wheelchairs and un-accompanied minors(UM). Sometimes, when they are about 10 minutes off the ground on their trip away from the airport, they call back with the times they were off the gate, and off the ground.<br />
<br />
On the ground, there may also be company frequencies in the 460.675 - 460.900 range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 freq’s before it is announced. These are NOT listed at [http://www.airnav.com/airports/ AirNav]. <br />
<br />
You can also find other air-related frequencies used around a major airport by doing a Geo Search for the Lat/Lon of your airport. Go to:<br />

<br />
== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware] will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, and tracking if still enroute.<br />
<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br><br />

# 121.500 (guard) is used far more often to communicate with aircraft that have somehow strayed onto the wrong frequency, and ATC cannot get hold of them on their assigned frequency. If they are listening on 121.5 the controller will probably be able to get through to them and get them back on the correct frequency. The monitoring of the 121.5 & 243 frequency via satellite will be eliminated in 2009. Apparently, 'they' are going to the 406 MHz satellite monitoring only. 406 MHz uses some digital encoding when broadcasting that can give aircraft details as well as GPS coordinates.<br />

<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS ([http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#ATIS Automatic Terminal Information Service])- Weather, equipment failures, closed runways and taxiways, current operating runways, special notes, and NOTAM's.<br />
# [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#Clearance Clearance Delivery] - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#Ground Ground Control] - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#Tower Tower] - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC Center] [([[http://www.freqofnature.com/index.php?m=ARTCC%20 Air Route Traffic Control Centers], commonly called [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#AirTrafficControl Air Traffic Control]). <br />
#Approach Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />

== Company Airlines Operational Control ==<br />
When aircraft are within 20-30 minutes of their destination, they call in on freq's 128.825 - 132.000 and 136.500 - 136.975 to report equipment malfunctions, delays, rerouting, and the special needs, such as wheelchairs and un-accompanied minors(UM). Sometimes, when they are about 10 minutes off the ground on their trip away from the airport, they call back with the times they were off the gate, and off the ground.<br />
<br />
On the ground, there may also be company frequencies in the 460.675 - 460.900 range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 freq’s before it is announced. These are NOT listed at [http://www.airnav.com/airports/ AirNav]. <br />
<br />
You can also find other air-related frequencies used around a major airport by doing a Geo Search for the Lat/Lon of your airport. Go to:<br />

<br />
== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware] will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, and tracking if still enroute.<br />
<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br><br />

The monitoring of the 121.5 & 243 frequency via satellite will be eliminated in 2009.

<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS ([http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#ATIS Automatic Terminal Information Service])- Weather, equipment failures, closed runways and taxiways, current operating runways, special notes, and NOTAM's.<br />
# [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#Clearance Clearance Delivery] - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# Ground Control - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#Tower Tower] - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC] (Air Route Traffic Control Center, commonly called [http://www.freqofnature.com/index.php?m=Aviation%20Monitoring&p=Aviation%20Monitoring#AirTrafficControl Air Traffic Control]). <br />
#Approach Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />

== Company Airlines Operational Control ==<br />
When aircraft are within 20-30 minutes of their destination, they call in on freq's 128.825 - 132.000 and 136.500 - 136.975 to report equipment malfunctions, delays, rerouting, and the special needs, such as wheelchairs and un-accompanied minors(UM). Sometimes, when they are about 10 minutes off the ground on their trip away from the airport, they call back with the times they were off the gate, and off the ground.<br />
<br />
On the ground, there may also be company frequencies in the 460.675 - 460.900 range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 freq’s before it is announced. These are NOT listed at [http://www.airnav.com/airports/ AirNav]. <br />
<br />
You can also find other air-related frequencies used around a major airport by doing a Geo Search for the Lat/Lon of your airport. Go to:<br />

<br />
== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware] will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, and tracking if still enroute.<br />
<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br><br />

<br />
== Google Earth 3D tracking ==<br />
With Google Earth installed on your PC, you can not only track one or several flights, but you can “rotate” the view when a plane is near an airport and see it actually descending or climbing. This is really neat! Download [http://earth.google.com/download-earth.html Google Earth] free.<br />

<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS (Automatic Terminal Information Service)- Weather, equipment failures, closed runways and taxiways, current operating runways, special notes, and NOTAM's.<br />
# Clearance Delivery - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# Ground Control - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# Tower - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC] (Air Route Traffic Control Center, commonly called Air Traffic Control). <br />
#Approach Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />

== Company Airlines Operational Control ==<br />
When aircraft are within 20-30 minutes of their destination, they call in on freq's 128.825 - 132.000 and 136.500 - 136.975 to report equipment malfunctions, delays, rerouting, and the special needs, such as wheelchairs and un-accompanied minors(UM). Sometimes, when they are about 10 minutes off the ground on their trip away from the airport, they call back with the times they were off the gate, and off the ground.<br />
<br />
On the ground, there may also be company frequencies in the 460.675 - 460.900 range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 freq’s before it is announced. These are NOT listed at [http://www.airnav.com/airports/ AirNav]. <br />
<br />
You can also find other air-related frequencies used around a major airport by doing a Geo Search for the lon/lat of your airport. Go to:<br />

<br />
== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware] will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, and tracking if still enroute.<br />
<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br><br />

</blockquote><br />
<br />
== Google Earth 3D tracking ==<br />
With Google Earth installed on your PC, you can not only track one or several flights, but you can “rotate” the view when a plane is near an airport and see it actually descending or climbing. This is really neat! Download [http://earth.google.com/download-earth.html Google Earth] free.<br />
Then go to [http://www.fboweb.com/antest/ge/intro.aspx?old=1 FBOWeb General Apps] or <br />
[http://www.fboweb.com/fb40/s/tr/qt.aspx?ss=1 FBOWeb Specific Flights]<br />
<br />
Enter airline flight info, and click on the “Track in 3D” button. It will “install” the specific flight <br />
as a layer on Google Earth, and will also track aircraft in the general vicinity.<br />
== Identifying Frequency vs. Airport ==<br />
When searching or monitoring the airport specific frequencies, such as Aproach/Departure, Clearance Delivery, Tower, ATIS, etc you can usually find out what airport you are hearing by typing '''airnav freq state''', into a Google search box.<br />
I.E. '''airnav 128.7 Pennsylvania'''<br />
<br />
== Notes ==<br />
# 121.500 (guard) is used far more often to communicate with aircraft that have somehow strayed onto the wrong frequency, and ATC cannot get hold of them on their assigned frequency. If they are listening on 121.5 the controller will probably be able to get through to them and get them back on the correct frequency. The monitoring of the 121.5 & 243 frequency via satellite will be eliminated in 2009. Apparently, 'they' are going to the 406 MHz satellite monitoring only. 406 MHz uses some digital encoding when broadcasting that can give aircraft details as well as GPS coordinates.<br />

When aircraft are within 20-30 minutes of their destination, they call in on freq's 128.825 - 132.000 and 136.500 - 136.975 to report equipment malfunctions, delays, rerouting, and the special needs, such as wheelchairs and un-accompanied minors(UM). Sometimes, when they are about 10 minutes off the ground on their trip away from the airport, they call back with the times they were off the gate, and off the ground.<br />
<br />
On the ground, there may also be company frequencies in the 460.675 - 460.900 range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 freq’s before it is announced. These are NOT listed at [http://www.airnav.com/airports/ AirNav]. <br />
<br />
You can also find other air-related frequencies used around a major airport by doing a Geo Search for the lon/lat of your airport. Go to:<br />

== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware] will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, and tracking if still enroute.<br />
<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br><br />

as a layer on Google Earth, and will also track aircraft in the general vicinity.<br />
== Identifying Frequency vs. Airport ==<br />
When searching or monitoring the airport specific frequencies, such as Aproach/Departure, Clearance Delivery, Tower, ATIS, etc you can usually find out what airport you are hearing by typing '''airnav freq state''', into a Google search box.<br />

== Notes ==<br />
# 121.500 (guard) is used far more often to communicate with aircraft that have somehow strayed onto the wrong frequency, and ATC cannot get hold of them on their assigned frequency. If they are listening on 121.5 the controller will probably be able to get through to them and get them back on the correct frequency. The monitoring of the 121.5 & 243 frequency via satellite will be eliminated in 2009. Apparently, 'they' are going to the 406 MHz satellite monitoring only. 406 MHz uses some digital encoding when broadcasting that can give aircraft details as well as GPS coordinates.<br />

<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS (Automatic Terminal Information Service)- Weather, equipment failures, closed runways and taxiways, gives the current operating runways, special notes, and NOTAM's.<br />
# Clearance Delivery - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# Ground Control - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# Tower - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC] (Air Route Traffic Control Center, commonly called Air Traffic Control). <br />
#Approach Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />

You can also find other air-related frequencies used around a major airport by doing a Geo Search for the lon/lat of your airport. Go to:<br />
<BLOCKQUOTE><br />
* [http://wireless2.fcc.gov/UlsApp/UlsSearch/searchGeographic.jsp FCC Geographic Search]<br />

<br />
== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, tracking if still enroute.<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br><br />

</blockquote><br />
<br />
== Google Earth 3D tracking ==<br />
With Google Earth installed on your PC, you can not only track one or several flights, but you can “rotate” the view when a plane is near an airport and see it actually descending or climbing. This is really neat! Download [http://earth.google.com/download-earth.html Google Earth] free.<br />
Then go to [http://www.fboweb.com/antest/ge/intro.aspx?old=1 FBOWeb General Apps] or <br />
[http://www.fboweb.com/fb40/s/tr/qt.aspx?ss=1 FBOWeb Specific Flights]<br />
<br />
Enter airline flight info, and click on the “Track in 3D” button. It will “install” the specific flight <br />
as a layer on Google Earth, and will also track aircraft in the general vicinity.<br />
== Identifying Frequency vs. Airport ==<br />
When searching or monitoring the airport specific frequencies, such as Aproach/Departure, Clearance Delivery, Tower, ATIS, etc you can usually find out what airport you are hearing by typing '''airnav freq state''', into a Google search box.<br />
I.E. '''airnav 128.7 Pennsylvania'''<br />
<br />
== Notes ==<br />
# 121.500 (guard) is used far more often to communicate with aircraft that have somehow strayed onto the wrong frequency, and ATC cannot get hold of them on their assigned frequency. If they are listening on 121.5 the controller will probably be able to get through to them and get them back on the correct frequency. The monitoring of the 121.5 & 243 frequency via satellite will be eliminated in 2009. Apparently, 'they' are going to the 406 MHz satellite monitoring only. 406 MHz uses some digital encoding when broadcasting that can give aircraft details as well as GPS coordinates.<br />

<hr />
<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS (Automatic Terminal Information Service)- Weather, equipment failures, closed runways and taxiways, gives the current operating runways, special notes, and NOTAM's.<br />
# Clearance Delivery - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# Ground Control - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# Tower - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC] (Air Route Traffic Control Center, commonly called Air Traffic Control). <br />
#Approach Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />

<br />
== Company Communications ==<br />
When aircraft are within 20-30 minutes of their destination, they call in on freq's 128.825 - 132.000 and 136.500 - 136.975 to report equipment malfunctions, delays, rerouting, and the special needs, such as wheelchairs and un-accompanied minors(UM). Sometimes, when they are about 10 minutes off the ground on their trip away from the airport, they call back with the times they were off the gate, and off the ground.<br />
<br />
On the ground, there may also be company frequencies in the 460.675 - 460.900 range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 freq’s before it is announced. These are NOT listed at [http://www.airnav.com/airports/ AirNav]. <br />
<br />
You can also find other air-related frequencies used around a major airport by doing a Geo Search for the lon/lat of your airport. Go to:<br />

<br />
== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, tracking if still enroute.<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br><br />

<br>[http://worldaerodata.com/countries/ World Aeronautical Database]<br />
</blockquote><br />
<br />
== Google Earth 3D tracking ==<br />
With Google Earth installed on your PC, you can not only track one or several flights, but you can “rotate” the view when a plane is near an airport and see it actually descending or climbing. This is really neat! Download [http://earth.google.com/download-earth.html Google Earth] free.<br />
Then go to [http://www.fboweb.com/antest/ge/intro.aspx?old=1 FBOWeb General Apps] or <br />
[http://www.fboweb.com/fb40/s/tr/qt.aspx?ss=1 FBOWeb Specific Flights]<br />
<br />
Enter airline flight info, and click on the “Track in 3D” button. It will “install” the specific flight <br />
as a layer on Google Earth, and will also track aircraft in the general vicinity.<br />
== Identifying Frequency vs. Airport ==<br />
When searching or monitoring the airport specific frequencies, such as Aproach/Departure, Clearance Delivery, Tower, ATIS, etc you can usually find out what airport you are hearing by typing '''airnav freq state''', into a Google search box.<br />
I.E. '''airnav 128.7 Pennsylvania'''<br />
<br />
== Notes ==<br />
# 121.500 (guard) is used far more often to communicate with aircraft that have somehow strayed onto the wrong frequency, and ATC cannot get hold of them on their assigned frequency. If they are listening on 121.5 the controller will probably be able to get through to them and get them back on the correct frequency. The monitoring of the 121.5 & 243 frequency via satellite will be eliminated in 2009. Apparently, 'they' are going to the 406 MHz satellite monitoring only. 406 MHz uses some digital encoding when broadcasting that can give aircraft details as well as GPS coordinates.<br />

<hr />
<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS (Automatic Terminal Information Service)- Weather, equipment failures, closed runways and taxiways, gives the current operating runways, special notes, and NOTAM's.<br />
# Clearance Delivery - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# Ground Control - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# Tower - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC] (Air Route Traffic Control Center, commonly called Air Traffic Control). <br />
#Approach Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />
== General Frequencies ==<br />

<br />
== Company Communications ==<br />
When aircraft are within 20-30 minutes of their destination, they call in on freq's 128.825 - 132.000 and 136.500 - 136.975 to report equipment malfunctions, delays, rerouting, and the special needs, such as wheelchairs and un-accompanied minors(UM). Sometimes, when they are about 10 minutes off the ground on their trip away from the airport, they call back with the times they were off the gate, and off the ground.<br />
<br />
On the ground, there may also be company frequencies in the 460.675 - 460.900 range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 freq’s before it is announced. These are NOT listed at [http://www.airnav.com/airports/ AirNav]. <br />
<br />
You can also find other air-related frequencies used around a major airport by doing a Geo Search for the lon/lat of your airport. Go to:<br />
<BLOCKQUOTE><br />
* [http://wireless2.fcc.gov/UlsApp/UlsSearch/searchGeographic.jsp FCC Geographic Search]<br />

* Hit the search.<br />
</BLOCKQUOTE><br />
<br />
== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, tracking if still enroute.<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br><br />

</blockquote><br />
<br />
== Google Earth 3D tracking ==<br />
With Google Earth installed on your PC, you can not only track one or several flights, but you can “rotate” the view when a plane is near an airport and see it actually descending or climbing. This is really neat! Download [http://earth.google.com/download-earth.html Google Earth] free.<br />

[http://www.fboweb.com/fb40/s/tr/qt.aspx?ss=1 FBOWeb Specific Flights]<br />
<br />
Enter airline flight info, and click on the “Track in 3D” button. It will “install” the specific flight <br />
as a layer on Google Earth, and will also track aircraft in the general vicinity.<br />
== Identifying Frequency vs. Airport ==<br />
When searching or monitoring the airport specific frequencies, such as Aproach/Departure, Clearance Delivery, Tower, ATIS, etc you can usually find out what airport you are hearing by typing '''airnav freq state''', into a Google search box.<br />
I.E. '''airnav 128.7 Pennsylvania'''<br />
<br />
== Notes ==<br />
# 121.500 (guard) is used far more often to communicate with aircraft that have somehow strayed onto the wrong frequency, and ATC cannot get hold of them on their assigned frequency. If they are listening on 121.5 the controller will probably be able to get through to them and get them back on the correct frequency. The monitoring of the 121.5 & 243 frequency via satellite will be eliminated in 2009. Apparently, 'they' are going to the 406 MHz satellite monitoring only. 406 MHz uses some digital encoding when broadcasting that can give aircraft details as well as GPS coordinates.<br />

== Company Communications ==<br />
When aircraft are within 20-30 minutes of their destination, they call in on freq's 128.825 - 132.000 and 136.500 - 136.975 to report equipment malfunctions, delays, rerouting, and the special needs, such as wheelchairs and un-accompanied minors(UM). Sometimes, when they are about 10 minutes off the ground on their trip away from the airport, they call back with the times they were off the gate, and off the ground.<br />
<br />
On the ground, there may also be company frequencies in the 460.675 - 460.900 range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 freq’s before it is announced. These are NOT listed at [http://www.airnav.com/airports/ AirNav]. <br />
<br />
You can also find other air-related frequencies used around a major airport by doing a Geo Search for the lon/lat of your airport. Go to:<br />

<br />
== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, tracking if still enroute.<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br><br />

== Google Earth 3D tracking ==<br />
With Google Earth installed on your PC, you can not only track one or several flights, but you can “rotate” the view when a plane is near an airport and see it actually descending or climbing. This is really neat! Download [http://earth.google.com/download-earth.html Google Earth] free.<br />

<br />
Enter airline flight info, and click on the “Track in 3D” button. It will “install” the specific flight <br />
as a layer on Google Earth, and will also track aircraft in the general vicinity.<br />
== Identifying Frequency vs. Airport ==<br />
When searching or monitoring the airport specific frequencies, such as Aproach/Departure, Clearance Delivery, Tower, ATIS, etc you can usually find out what airport you are hearing by typing '''airnav freq state''', into a Google search box.<br />
I.E. '''airnav 128.7 Pennsylvania'''<br />
<br />
== Notes ==<br />
# 121.500 (guard) is used far more often to communicate with aircraft that have somehow strayed onto the wrong frequency, and ATC cannot get hold of them on their assigned frequency. If they are listening on 121.5 the controller will probably be able to get through to them and get them back on the correct frequency. The monitoring of the 121.5 & 243 frequency via satellite will be eliminated in 2009. Apparently, 'they' are going to the 406 MHz satellite monitoring only. 406 MHz uses some digital encoding when broadcasting that can give aircraft details as well as GPS coordinates.<br />

<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS (Automatic Terminal Information Service)- Weather, equipment failures, closed runways and taxiways, gives the current operating runways, special notes, and NOTAM's.<br />
# Clearance Delivery - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# Ground Control - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# Tower - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC] (Air Route Traffic Control Center, commonly called Air Traffic Control). <br />
#Approach Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />

For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, tracking if still enroute.<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br><br />

== Notes ==<br />
# 121.500 (guard) is used far more often to communicate with aircraft that have somehow strayed onto the wrong frequency, and ATC cannot get hold of them on their assigned frequency. If they are listening on 121.5 the controller will probably be able to get through to them and get them back on the correct frequency. The monitoring of the 121.5 & 243 frequency via satellite will be eliminated in 2009. Apparently, 'they' are going to the 406 MHz satellite monitoring only. 406 MHz uses some digital encoding when broadcasting that can give aircraft details as well as GPS coordinates.<br />

<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS (Automatic Terminal Information Service)- Weather, equipment failures, closed runways and taxiways, gives the current operating runways, special notes, and NOTAM's.<br />
# Clearance Delivery - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# Ground Control - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# Tower - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC] (Air Route Traffic Control Center, commonly called Air Traffic Control). <br />
#Approach Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />

== Company Communications ==<br />
When aircraft are within 20-30 minutes of their destination, they call in on freq's 128.825 - 132.000 and 136.500 - 136.975 to report equipment malfunctions, delays, rerouting, and the special needs, such as wheelchairs and un-accompanied minors(UM). Sometimes, when they are about 10 minutes off the ground on their trip away from the airport, they call back with the times they were off the gate, and off the ground.<br />
<br />
On the ground, there may also be company frequencies in the 460.675 - 460.900 range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 freq’s before it is announced. These are NOT listed at [http://www.airnav.com/airports/ AirNav]. <br />
<br />
You can also find other air-related frequencies used around a major airport by doing a Geo Search for the lon/lat of your airport. Go to:<br />

<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS (Automatic Terminal Information Service)- Weather, equipment failures, closed runways and taxiways, gives the current operating runways, special notes, and NOTAM's.<br />
# Clearance Delivery - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# Ground Control - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# Tower - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC] (Air Route Traffic Control Center, commonly called Air Traffic Control). <br />
#Approach Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />

== Company Ground Communications ==<br />
When aircraft are within 20-30 minutes of their destination, they call in on freq's 128.825 - 132.000 and 136.500 - 136.975 to report equipment malfunctions, delays, rerouting, and the special needs, such as wheelchairs and un-accompanied minors(UM). Sometimes, when they are about 10 minutes off the ground on their trip away from the airport, they call back with the times they were off the gate, and off the ground.<br />
== Company Ground Communications ==<br />
On the ground, there may also be company frequencies in the 460.675 - 460.900 range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 freq’s before it is announced. These are NOT listed at [http://www.airnav.com/airports/ AirNav]. <br />
<br />
You can also find other air-related frequencies used around a major airport by doing a Geo Search for the lon/lat of your airport. Go to:<br />

== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, tracking if still enroute.<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br><br />

== Google Earth 3D tracking ==<br />
With Google Earth installed on your PC, you can not only track one or several flights, but you can “rotate” the view when a plane is near an airport and see it actually descending or climbing. This is really neat! Download [http://earth.google.com/download-earth.html Google Earth] free.<br />

<br />
Enter airline flight info, and click on the “Track in 3D” button. It will “install” the specific flight <br />
as a layer on Google Earth, and will also track aircraft in the general vicinity.<br />
== Identifying Frequency vs. Airport ==<br />
When searching or monitoring the airport specific frequencies, such as Aproach/Departure, Clearance Delivery, Tower, ATIS, etc you can usually find out what airport you are hearing by typing '''airnav freq state''', into a Google search box.<br />

== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, tracking if still enroute.<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br />

<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS (Automatic Terminal Information Service)- Weather, equipment failures, closed runways and taxiways, gives the current operating runways, special notes, and NOTAM's.<br />
# Clearance Delivery - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# Ground Control - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# Tower - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC] (Air Route Traffic Control Center, commonly called Air Traffic Control). <br />

== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, tracking if still enroute.<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard.

<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS (Automatic Terminal Information Service)- Weather, equipment failures, closed runways and taxiways, gives the current operating runways, special notes, and NOTAM's.<br />
# Clearance Delivery - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# Ground Control - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# Tower - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC] (Air Route Traffic Control Center, commonly called Air Traffic Control). <br />
#Approach Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />

== Notes ==<br />
# 121.500 (guard) is used far more often to communicate with aircraft that have somehow strayed onto the wrong frequency, and ATC cannot get hold of them on their assigned frequency. If they are listening on 121.5 the controller will probably be able to get through to them and get them back on the correct frequency. The monitoring of the 121.5 & 243 frequency via satellite will be eliminated in 2009. Apparently, 'they' are going to the 406 MHz satellite monitoring only. 406 MHz uses some digital encoding when broadcasting that can give aircraft details as well as GPS coordinates.<br />

<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS (Automatic Terminal Information Service)- Weather, equipment failures, closed runways and taxiways, gives the current operating runways, special notes, and NOTAM's.<br />
# Clearance Delivery - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# Ground Control - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# Tower - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC] (Air Route Traffic Control Center, commonly called Air Traffic Control). <br />
#Approach Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />

== Company Ground Communications ==<br />
When aircraft are within 20-30 minutes of their destination, they call in on freq's 128.825 - 132.000 and 136.500 - 136.975 to report equipment malfunctions, delays, rerouting, and the special needs, such as wheelchairs and un-accompanied minors(UM). Sometimes, when they are about 10 minutes off the ground on their trip away from the airport, they call back with the times they were off the gate, and off the ground.<br />
== Company Ground Communications ==<br />
On the ground, there may also be company frequencies in the 460.675 - 460.900 range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 freq’s before it is announced. These are NOT listed at [http://www.airnav.com/airports/ AirNav]. <br />

== Identifying Aircraft vs. Frequency ==<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, tracking if still enroute.<br />
== CodeShare (Airline Partners)==<br />
Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. [http://www.flightstats.com/go/Home/home.do Flight Stats] shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br />

<div>== Overview ==<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS (Automatic Terminal Information Service)- Weather, equipment failures, closed runways and taxiways, gives the current operating runways, special notes, and NOTAM's.<br />
# Clearance Delivery - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# Ground Control - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# Tower - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC] (Air Route Traffic Control Center, commonly called Air Traffic Control). <br />

Another confusing area is the [http://en.wikipedia.org/wiki/Codeshare Codeshare]. It refers to a practice where a flight operated by an airline is jointly marketed as a flight for one or more other airlines. Most major airlines today have code sharing partnerships with other airlines. For example, Delta has feeder airline partners with Comair, Chautauqua, Atlantic Southeast, etc. So Delta DL456, operated by ComAir, might be COM456, or even COM56. Flight Stats http://www.flightstats.com/go/Home/home.do shows both. However, this does not always relate to what you heard. There are many other similar tracking sites, and they don’t always show the exact same thing, so it is good to use more than one. <br />

Google Earth 3D tracking<br />
With Google Earth installed on your PC, you can not only track one or several flights, but you can “rotate” the view when a plane is near an airport and see it actually descending or climbing. This is really neat! To get Google Earth, download free at: http://earth.google.com/download-earth.html<br />
Then go to:<br />
[http://www.fboweb.com/antest/ge/intro.aspx?old=1 FBOWeb] or <br />
[http://www.fboweb.com/fb40/s/tr/qt.aspx?ss=1 FBOWeb]<br />
<br />
Enter airline flight info, and click on the “Track in 3D” button. It will “install” the specific flight <br />
as a layer on Google Earth, and will also track aircraft in the general vicinity.<br />
<br />
Identifying Frequency vs. Airport<br />
When searching or monitoring the airport specific frequencies, such as Aproach/Departure, Clearance Delivery, Tower, ATIS, etc you can usually find out what airport you are hearing by typing “airnav freq state, into a Google search box.<br />
I.E. “airnav 128.7 Pennsylvania”, <br />
Note: you can also find other air-related frequencies used around a major airport by doing a Geo Search for the lon/lat of your airport. See note 3<br />
<br />
Notes<br />
# 121.500 (guard) is used far more often to communicate with aircraft that have somehow strayed onto the wrong frequency, and ATC cannot get hold of them on their assigned frequency. If they are listening on 121.5 the controller will probably be able to get through to them and get them back on the correct frequency. The monitoring of the 121.5 & 243 frequency via satellite will be eliminated in 2009. Apparently, 'they' are going to the 406 MHz satellite monitoring only. 406 MHz uses some digital encoding when broadcasting that can give aircraft details as well as GPS coordinates.<br />

<div>Commercial Airline Tips for Tracking & Monitoring<br />
<br />
Airborne planes can easily be heard from well over 100 miles, so you don't have to live near an airport. If you do live near an airport, you can find out all the traffic control, weather, and Traffic Advisory frequencies by entering the airport at [http://www.airnav.com/airports/ AirNav]<br />
<br />
At most small airports that don't have control towers, the UNICOM frequency is used by the pilots use to talk to each other, usually 122.900 or 122.950. At larger airports that have control towers, most airports have the following types of channels:<br />
# ATIS (Automatic Terminal Information Service)- Weather, equipment failures, closed runways and taxiways, gives the current operating runways, special notes, and NOTAM's.<br />
# Clearance Delivery - The pilot uses this frequency to notify a controller of his flight intentions and to receive flight instructions and clearance for take-off. <br />
# Ground Control - The ground controller tells the pilot which taxiways to use to arrive at the correct runway.<br />
# Tower - The Tower Controller is responsible for the aircraft in the immediate area around the airport (Up to 3000 feet and 5 miles from the airport). Once the aircraft leaves the airspace of the airport, the pilot will be handed off to a controller at a [http://wiki.radioreference.com/index.php/TRACON TRACON] (Terminal Radar Approach Control) or an [http://wiki.radioreference.com/index.php/ARTCC ARTCC] (Air Route Traffic Control Center, commonly called Air Traffic Control). Approach Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Directs several lines of descending aircraft into one smooth flowing line of aircraft as their courses take them closer to the destination airport. <br />
# Departure Control([http://wiki.radioreference.com/index.php/TRACON TRACON]) - Routes air traffic immediately upon takeoff via a preferential departure route (PDR) leading away from the departure airport as the aircraft ascends to the en route phase of flight.<br />

Company Ground Communicatiions<br />
On the ground, there may also be company frequencies in the 460.675 - 460.900 range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 freq’s before it is announced. These are NOT listed at [http://www.airnav.com/airports/ AirNav]. See note 3.<br />
<br />
Identifying Aircraft vs. Frequency<br />
<br />
All commercial and private call-signs in the United States start with the letter 'N'. However, the ‘N’ is usually not used for commercial flights. Pilots often just use the last two or three digits of the call-sign to save precious air time. This can be very confusing, but [http://flightaware.com/live/airport/ FlightAware will give you a list of possible flights with every combination of those numbers. For instance, if you enter ComAir 5650 in the flight #, or COM5650 in the Flight/Tail #, you should be able to see that it is really ComAir #50. This will give you departure/arrival airports, tracking if still enroute.<br />
