Are aircraft frequencies AM or FM?
Aviation doesn’t use AM radio broadcast frequencies (565 to 1605 KHz).
They use AM modulation on Non-Directional Beacons (NDBs) below those frequencies, and they use mostly Single Sideband instead of AM modulation on HF frequencies (3–30 MHz)..
What is a talk around frequency?
It means “talking around the repeater”. So, Talk-a-Round (aka Direct) is where the mobile or portable talks simplex to others on the output frequency of the repeater they normally use. It is primarily used when a repeater is out of service, or you are out of range of it.
Do all ATC speak English?
Yes. English is the official, only, language for ATC(Air Traffic Control) as per ICAO standards. The International Civil Aviation Organization(ICAO) is a branch of the United Nations which creates the world standards for safe flying. Everyone has to understand each other without fail.
What does heavy mean in airline speak?
Heavy (aeronautics) From Wikipedia, the free encyclopedia. In the United States, the term heavy is used during radio transmissions between air traffic control and any aircraft which has been assigned a maximum takeoff weight (MTOW) rating of 136 tonnes (300,000 lb) or more.
Why do pilots salute before takeoff?
All pilots salute to signify they are ready for takeoff. They aren’t even supposed to put their arms above the canopy rail to avoid accidental shots. There are hold bars on the throttles of some planes to avoid a situation where the throttles go to idle during the shot.
Is 121.5 still monitored?
Flight Service Stations will con- tinue to monitor 121.5 MHz, and aircraft pilots are technically still required to monitor this frequency at all times if it’s possible with installed equipment. After all, 121.5 MHz still remains the GARD frequency for airborne emergencies.

Why is AM radio bad?
AM transmissions are much more susceptible than FM or digital signals are to interference, and often have lower audio fidelity. Thus, AM broadcasters tend to specialise in spoken-word formats, such as talk radio, all news and sports, leaving the broadcasting of music mainly to FM and digital stations.
What radio frequencies can I use without a license?
There are ZERO unlicensed frequencies you can transmit on LEGALLY w/o a license. Out of the box, Ch 6 are Ch 7 of this radio are the only legal channels to transmit in the USA without a license. These correspond to FRS/GMRS 18 (with CTCSS 19) and FRS/GMRS 22 (with CTCSS 21).
Is listening to air traffic control illegal?
You can listen to air traffic control radio transmissions It is illegal under the Wireless Telegraphy Act 1949 2006 to listen to anything other than general reception transmissions unless you are either a licensed user of the frequencies in question or have been specifically authorised to do so by a designated person.
Can you listen to ATC on a plane?
The Live ATC app lets you to listen into the world of air traffic control at not only your flight’s airport, but airports around the world. … While boarding, you may capture chatter about when your flight will leave, including details like how many planes are ahead of you and which path the aircraft will taxi on.
How do I find flight frequency?
The Flight Service frequencies are listed in a box above certain VOR stations. The most common frequencies are 122.2, 122.4, or 122.6. Also, most GPS (or iPad apps like ForeFlight) have a listing of the nearest Flight Service frequencies.
What is clearance delivery frequency?
Clearance Delivery Frequency is initial clearance from ATC before you take off. The idea behind using a dedicated frequency for this is that it avoids tying up the ground control frequency (used for authorizing ground movement on taxiways and such) with long clearances and readbacks.
Is UHF FM or AM?
UHF = Ultra High Frequency and has NOTHING to do with whether the signal is AM, FM or something else. In other words, UHF refers to the “band” that the frequency is in. AM and FM are types of modulation. There are plenty of other modes of modulation as well.
What radio frequency do planes use?
Legally, for air-to-air communications between private, fixed-wing aircraft, there is just one authorized frequency: 122.75 MHz. For general aviation helicopters: 123.025 MHz. Gliders and hot air balloons share 123.3 and 123.5 MHz.
What is the best frequency to listen to aircraft?
Listening to Aircraft At most small airports that don’t have control towers, most action will occur on the UNICOM frequency, typically 122.900 or 122.950. Other less common UNICOM frequencies are 122.700, 122.725, 122.800, 122.975, 123.000, 123.050, or 123.075 MHz.
Can two way radios communicate with CB?
A: Typically, CB radios can only communicate with other CB radios – It is unlikely that your handheld devices will send and receive transmissions.
What does squawk 7777 mean?
military interception§ 7777: § military interception (US) (“Under no circumstances should a pilot of a civil aircraft operate the transponder on Code 7777. This code is reserved for military interceptor operations.”) § non-discrete code used by fixed test transponders (RABMs) to check correctness of radar stations (BITE).
