Anyone can tune into airport frequencies, and there are several online platforms that allow you to do so. LiveATC, for example, is a popular platform that provides live ATC feeds from over 1,000 airports worldwide. It is a non-profit project where aviation enthusiasts broadcast ATC communications, and it offers both a website and a mobile app. Other platforms and tools, such as flight trackers like Flightradar24 and FlightAware, also enable users to listen to ATC conversations and match them with specific flights and aircraft. While some countries have restrictions on streaming ATC feeds, owning a radio scanner and tuning into ATC transmissions is generally allowed and accessible to anyone.

LiveATC is a popular platform for listening to ATC feeds
LiveATC's radio feeds come from people who set up a receiver that feeds the site. One such person set up a feed at their local airport terminal building using a Raspberry Pi computer with a Software Defined Radio (SDR) attached to a 126.0 mHz antenna, which feeds Unicom/CTAF to LiveATC. They use this as a teaching tool, helping students learn how to make a little radar in their heads of the traffic around them, and get used to listening to ATC and what to say when talking back.
LiveATC also has an app called LiveATC Air Radio, which provides a quick and easy way to listen in on live conversations between pilots and air traffic controllers near many airports around the world. The app lets you browse by U.S. state, Canadian province, or by country to find an airport of interest. Once you find an interesting channel, you can add it to your Favorites list for quick and easy access. You can also use the Nearby function to find airports near you.
However, it is important to note that LiveATC does not have coverage in certain countries, including the U.K., Belgium, France, Germany, Iceland, Italy, New Zealand, and Spain, where streaming ATC communications may be prohibited by law. Available airports and channels are also subject to change at any time.

Common ATC frequencies include 121.5, 122.750 MHz, 123.025 MHz, 123.450 MHz, and 128.825-132.000 MHz
Anyone can tune into airport frequencies, and there are several platforms that allow you to do so. LiveATC is a popular platform for listening in on ATC feeds, and it doesn't require any special equipment. It is a non-profit project where aviation enthusiasts worldwide broadcast the ATC communications near them for anyone to listen to. The LiveATC.net app is available for Android and iOS devices.
There are several common ATC frequencies that can be tuned into, and they are mostly universal, regardless of the airport. These include:
- 121.5: This is the emergency frequency. Pilots will transmit on this frequency in case of an emergency, and an emergency locator beacon can also be heard if a plane crashes.
- 122.750 MHz: This frequency is used for general aviation air-to-air communications.
- 123.025 MHz: Helicopters use this frequency for air-to-air communications.
- 123.450 MHz: This is the "unofficial" frequency for air-to-air communications.
- 128.825-132.000 MHz: These are the ARINC frequencies used by airlines, corporate aviation, and general aviation when calling ahead for fuel, parking, and other requests. This range also includes ramp frequencies, which are seldom published by the FAA.
It is worth noting that ATC frequencies are spaced at 0.025 MHz intervals, and the third decimal place is sometimes omitted when reading back frequencies. For example, 121.5 is often referred to as just "121" in ground communications.

Live flight trackers like Flightradar24 and FlightAware show aircraft callsigns and positions
Live flight trackers like Flightradar24 and FlightAware provide real-time updates on aircraft callsigns and positions. Flightradar24, for instance, combines data from various sources, including ADS-B, MLAT, satellite, and radar data, to offer a comprehensive flight-tracking experience. It relies on aircraft with ADS-B transponders to transmit flight information to its global network of over 50,000 ground-based receivers. While Flightradar24 does not explicitly label aircraft as "military," users can infer military presence by observing unusual patterns or cross-referencing callsigns with known military operations.
FlightAware, another popular flight tracker, also offers callsign tracking. It provides a platform for aviation enthusiasts to broadcast and access ATC communications from airports worldwide. While the specific functionalities of FlightAware regarding callsigns may differ, it is reasonable to expect features similar to those of Flightradar24.
These flight-tracking platforms are valuable tools for enthusiasts and professionals alike, providing insights into the dynamic world of aviation. They enhance awareness of air traffic and enable users to make more informed decisions, especially when complemented by resources like LiveATC for listening in on ATC feeds.
It is worth noting that, while these platforms provide extensive information, certain limitations exist. For instance, not all aircraft are equipped with ADS-B, and some may disable it for security reasons. Additionally, high-profile aircraft, such as Air Force One, may not be displayed due to security considerations. Nevertheless, Flightradar24 and FlightAware represent significant advancements in live flight tracking, empowering users with valuable data and contributing to a safer and more transparent aviation landscape.

Airlines with a small presence at an airport may use another airline's frequency
There are no official "national" company frequency allocations, but among larger airlines, there are common frequencies that you will find used by each at many different airports. These "common" frequencies are less likely to be valid in busier air traffic areas due to frequency congestion. Some common allocations include dispatch and operations frequencies. Dispatch frequencies are used to contact the airline's dispatch staff, usually located at the airline's headquarters, and maintenance staff. Operations frequencies are the main (and often the only) frequency used by aircraft to contact the airline's local airport staff when "in range" and on the ground. Airlines will usually have an operations frequency at their hub airports as well.
Regional airlines that use smaller aircraft without ACARS may have a common frequency to contact dispatch and other company pilots. ACARS has replaced most communications when aircraft are within 20-30 minutes of their destination, but some airlines will contract out ramp handling but have their own customer service staff, so they may have their own company frequency.
On the ground, airline ground operations are often found in the 460.65-460.9 MHz range. Flight delays, cancellations, or gate changes can often be found on these frequencies before they are announced.

ATC transmissions are open and free for anyone to receive
Another option is to use a radio scanner, which is legal to own and use in most places. You can tune your scanner to common ATC frequencies, such as 121.5 MHz for emergencies, 122.750 MHz for general aviation air-to-air communications, and 123.025 MHz for helicopters. You can also find airport-specific frequencies by using resources like the FAA's Aeronautical Information Service (AIS) or websites like AirNav and SkyVector. Additionally, you can use flight trackers like Flightradar24 or FlightAware to see the current position of aircraft and match them with ATC instructions.
It's worth noting that while ATC transmissions are unencrypted and accessible, you may encounter challenges in understanding the conversations due to the specialized terminology and procedures involved in aviation communications. Additionally, you might only be able to hear one side of the conversation, typically the aircraft, and not the controlling agency or ATC.

No, you don't need any special equipment to use LiveATC. However, if you want to provide a feed to LiveATC, you will need a VHF receiver, reliable internet, an external VHF antenna, and a mono audio cable.
Yes, there may be local laws that restrict or block streams in certain locations. For example, in the UK, an outdated 1942 law makes it illegal to stream ATC feeds. However, there are no restrictions on using your own radio scanner to tune into airport frequencies.
Some common airport frequencies include 121.5 MHz for emergencies, 122.750 MHz for general aviation air-to-air communications, and 123.025 MHz for helicopter air-to-air communications.
You can use the FAA's Aeronautical Information Service (AIS) search tool to find airport frequencies. Alternatively, you can use the SkyVector website to search for an airport by its ICAO designator and find the frequencies in the Airport Communications section.
