Aviation enthusiasts can listen in on air traffic control (ATC) communications using scanners and apps. All Air Traffic Control (ATC) channels rely on frequencies in the 118.000–136.975 MHz band, so any radio or scanner that can register these bands will work. It is important to note that while anyone can listen to ATC feeds and pilot communications, it is illegal to interfere or talk to an active aviation channel. Websites like LiveATC, globalair.com, airnav.com, and radioreference.com also provide access to live ATC streams.

Aviation scanners can be handheld, or installed in a vehicle or home
Aviation scanners are used to listen in on aviation communication, including air traffic controllers (ATC) and pilots, civilian aviation, and military aviation (Milcom). These scanners can be handheld, installed in a vehicle, or used in the home.
Handheld scanners are portable and can be carried around like a walkie-talkie. They typically last 4-6 hours per charge and use AA batteries. They are the most popular type of aviation scanner due to their portability and lower cost. Vehicle scanners, on the other hand, can be installed in the dashboard of a car, while home or "base" scanners are typically used in one location. The type of scanner purchased depends on personal preference and where it will be used. If using a scanner at home or in a vehicle, an antenna may be needed to increase the range of frequencies that can be picked up.
Aviation scanners can be purchased online and vary in price depending on their capabilities. Analog scanners, for example, cost around $100, while new digital scanners cost around $400. It is important to note that aviation frequencies are unique to each airport and rarely change. As such, scanners often need to be programmed to pick up the correct frequencies. Some people consider this programming part of the fun, while others prefer scanners that work out of the box.

Civilian Aviation Communication frequencies can be picked up by any scanner
Anyone can listen to civilian aviation communication frequencies using a scanner. Websites like LiveATC, globalair.com, airnav.com, and radioreference.com also provide access to live ATC streams.
Aviation scanners can be handheld or installed in a vehicle dashboard or home. Handheld scanners are portable and can be carried around like a walkie-talkie, while vehicle scanners are installed in the dashboard of a car or plane. Home scanners, or "base" scanners, are typically used in one location. The type of scanner purchased is based on personal preference and where the scanner will be used.
To listen to civilian aviation communication frequencies, a scanner capable of receiving frequencies between 118.0 and 136.975 MHz is needed. Good brands to check out include Uniden, Whistler, Icom, Yaesu, Grundig, and Kenwood. It is important to note that while anyone can listen to civilian aviation communication frequencies, it is illegal to interfere or communicate on aviation frequencies.
Listening to civilian aviation communication frequencies can be a great way to learn about aviation and how to communicate with air traffic control (ATC). ATC frequencies vary, so it may be necessary to search for the correct frequency. Automated weather and operational updates, such as those provided by AWOS, ASOS, and ATIS, can also provide valuable information about aviation conditions.

Military Aviation Communication frequencies require a phase 2 digital scanner
Aviation is a rich area for scanning enthusiasts, plane spotters, and aircraft enthusiasts. Military Aviation Communication, or milcom, is broadcast using two formats: analog and phase 2 digital. To listen to all military communications, you will need a phase 2 digital scanner.
Analog scanners are the most popular type of scanner as they cost around $100, whereas new digital scanners cost around $400. Military planes usually use analog channels at air shows so civilians can listen in.
There is no easy way to determine the broadcast format for each area, as milcom bands are not published for security reasons. The best way to find out is to ask other people in your area.
There are two types of aviation scanners: handheld and home/vehicle. Handheld scanners are portable and can be carried around like a walkie-talkie, while home/vehicle scanners can be installed in the dashboard of a vehicle or kept in one location. The type of scanner you buy depends on your personal preference and where you will be listening from.
Some scanners are actually transceivers, which allow for two-way communication. It is a serious crime to interfere or communicate on aviation frequencies that you are not authorised to participate in.
Aviation frequencies rarely, if ever, change. Once your scanner is programmed, you should be set.

ATC frequencies vary, so you may need to search for the correct one
Scanners can pick up airport frequencies, but ATC frequencies vary, so you may need to search for the correct one.
To listen to your local Air Traffic Control (ATC), you will need a radio scanner capable of reading frequencies in the 118-137 MHz band. All ATC channels rely on frequencies in the 118.000-136.975 MHz band, so any radio or scanner that can register these bands will work.
There are a handful of ATC and aviation-related frequencies that are universal, regardless of the airport. For example, 121.5 is the emergency frequency, and 122.750 MHz is the frequency for general aviation air-to-air communications. However, as ATC frequencies vary, you may need to search for the correct one for your local airport.
You can use your scanner's search function to find unique frequencies. Most scanners have an auto-search function that will automatically swap between active channels. You can also visit LiveATC online to listen to ATC feeds for free. LiveATC is the most popular platform for listening in on ATC feeds, and you don't need any equipment to do so. You can search for your desired airport on the website or search by region, city, or keyword.
It is important to note that if you have a two-way scanner that allows you to broadcast frequencies, you should never attempt to interfere or communicate on aviation frequencies. The penalties for doing so are severe.

It is illegal to interfere with aviation frequencies
Scanners are devices that can be used to listen to aviation frequencies. While listening to aviation frequencies is legal, interfering with them is not. It is a serious crime to mess with aviation channels, and authorities take this very seriously.
In the United States, for example, the Federal Communications Commission (FCC) prohibits interference with aviation frequencies. The law states that you cannot interfere with other equipment, and broadcasting on the same frequency as an aviation channel would certainly cause interference.
Similarly, in most countries, impersonating an air traffic controller is a criminal offense. Unauthorized transmissions on aviation frequencies can lead to loss of separation, loss of communication, airspace infringement, controlled flight into terrain, and general disruption of flight operations. These unauthorized transmissions can be identified by certain signs, such as only being received by the pilot or controller and containing obvious mistakes in phraseology.
To avoid any legal issues, it is important to only use scanners to listen to aviation frequencies and never to transmit or interfere with the communications in any way. Doing so could have severe consequences and pose a risk to aviation safety.
Therefore, while scanners can pick up airport frequencies, it is crucial to use them responsibly and refrain from any interference or unauthorized transmissions.

Frequently asked questions
You will need a scanner that can read frequencies in the 118-137 MHz band. All Air Traffic Control (ATC) channels rely on frequencies in this band. Good brands to check out include Uniden, Whistler, Icom, Yaesu, Grundig, and Kenwood.
Search 122.0-123.65 for Unicom (uncontrolled airports) and air-to-air communications. Search 128.825-132.000 MHz for ARINC frequencies (used by airlines, corporate aviation, and general aviation).
Most major airports are available. You can listen to ATC feeds and pilot communications as this is public information. You can also listen to air traffic control facilities from around the world at websites including liveatc.net, globalair.com, airnav.com, and radioreference.com.
No, it is a serious crime to interfere or talk to an active aviation channel. If you have a two-way scanner, do not attempt to broadcast on an aviation frequency.
