![]() ![]() ![]() Therefore, in most countries impersonating an air traffic controller is a criminal offense. Loss of Separation, Loss of Communication, Airspace Infringement, Controlled Flight Into Terrain (CFIT) and general disruption of flight operations. Therefore anyone with a radio operating in the airband (frequency range 118-137 MHz) is technically capable of listening to and sending voice messages.įollowing such an "instruction" may, depending on the specific circumstances, lead to e.g. VHF communication is not subject of any protection (e.g. Here is an article that goes into great detail regarding scanning laws in the US.Unauthorised use of ATC frequency is a situation where a person who is not an air traffic controller pretends to be one by transmitting radio messages to aircraft. Scanners work on line of site and from the tower 30-50 miles is the range. Aviation Scanning FAQ How Far Away Will My Aviation Scanner Work?Ībout 100 miles from planes in the sky, but from airports it will vary greatly based on where you live and what’s around you (buildings, trees, hills, etc.). If you are lucky or live close enough to an airport, you might be able to receive several of these frequencies. Once pilots are airborne, they will talk to an "approach/departure" frequency, and once in route, they might even talk to a "center" frequency. At larger airports, pilots receive their flight plan clearances from a "clearance delivery" frequency, communicate on taxiways with a "ground" frequency, and get takeoff and landing clearance from the "tower" frequency. If you have access to an airport/facility directory, you can find more frequencies than those available on the chart. These are automated or repeating broadcasts that provide pilots with weather and airport information as they prepare to land or depart. Some airports have AWOS (Automated Weather Observing System), ASOS (Automated Surface Observing System), or ATIS (Automated Terminal Information Service) frequencies listed on the chart. Listen to weather forecasts and airport information as you prepare to land. Airports with runways over 8,000 feet (2,438.4 m) are not enclosed in circles and simply have a diagram depicting the runway layout, which is outlined in blue (controlled) or magenta (uncontrolled). At this type of airport, pilots communicate directly with one another and tell each other their position and intentions.Īll controlled airports will be denoted by blue circles, while uncontrolled airports are magenta. ![]() A star will be after the tower frequency to denote that airport as having a part time tower. If the airport is uncontrolled (no tower) or the tower operates part time, a C in a circle after a frequency number will be used to denote a Common Traffic Advisory Frequency (CTAF). For example, the frequency for Wittman Regional airport in Oshkosh, WI is CT - 118.5. The control tower frequency is denoted by CT - 000.0, where the following numbers indicate the frequency used by ATC. Next to the circle is a block of text with the airport name and information about that airport. Online sectional charts for your local area are available on Find the closest airport on the chart.Īirports are denoted by blue or magenta circles, with lines inside representing runways. Older versions of these charts will usually work just fine. You most likely want to be looking for a chart of your local area from the closest airport. Search 128.825-132.000 MHz for ARINC frequencies (airlines, corporate aviation and general aviation calling ahead for fuel, parking, and other requests). Search 122.0-123.65 for Unicom (uncontrolled airports) and air to air communications. You could also hear an emergency locator beacon on this frequency if a plane crashes.ġ22.750 MHz is the frequency for general aviation air to air communicationsġ23.025 MHz is the frequency for helicopters air to air communicationsġ23.450 MHz is the "unofficial" frequency for air to air communications If there is some sort of emergency, pilots will transmit on it. You're better off selecting a good scanner instead of a general coverage unit, thanks to the scanner's ability to easily monitor multiple frequencies.ġ21.5 is the emergency frequency. Obtain a radio scanner that is capable of receiving frequencies between 118.0 and 136.975 MHz. Whether you are a student pilot, retired pilot or just want to know what's going on in the friendly skies, you can listen to air traffic controllers at work any time. Their communication is also accessible to the public. They communicate with pilots on designated radio frequencies to keep airport operations running smoothly and safely. Air traffic control (ATC) is responsible for providing crucial information to pilots around busy airports. ![]()
