FAQ: What Frequency Is 122.1 Used For In Aviation?

Where do I find FSS 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 frequency does aviation 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.

What radio frequency do pilots use?

One of its roles is to allocate all radio bandwidths and frequencies. In the United States, VHF civil aircraft communications are placed in the 100 MHz band and allocated 760 channels within the range from 118.0-136.975 MHz. As a pilot, every frequency you talk on will fall within this range.

How do you talk on VOR frequency?

Dial in the appropriate frequency on your COM (example: 121.1R) as specified on the VOR identity ‘box’ and also dial in the VOR’s frequency in your NAV radio. Make sure you have the NAV radio activated on your communication switch to hear its transmissions 3.

How do I listen to ATC frequencies?

If you’ve got nothing better to do on one night, visit LiveATC.net, where anyone with a computer or smartphone and a passing interest in aviation can listen to control towers live, worldwide, and in full action. Student pilots use it to listen to their local airport to get accustomed to the myriad radio calls required.

Are aviation 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 frequencies do police use?

Public Safety Spectrum

Frequency MHz Available for Public Safety
25-50 MHz (VHF Low Band) 6.3 MHz
150-174 MHz (VHF High Band) 3.6 MHz [non-contiguous]
220-222 (220 MHz band) 0.1 MHz
450-470 (UHF Band) 3.7 MHz [non-contiguous]

What frequency does the military use?

The military has a BIG (175 MHz) military aircraft band in the 225-400 MHz range. Basic spacing between channels is 25 kHz.

What type of frequency is 118.700 MHz?

Radio frequencies in use at this airport:

Name Frequency Type
Clark Tower 118.700 MHz Tower
Clark Approach 119.200 MHz Approach

How do pilots talk to ATC?

The most common form of communication in aviation, very high frequency (VHF) radio calls are what we use for around 95% of our communications with ATC. In simplified terms, the transmitting station sends a signal that travels in a straight line and is picked up by the receiving station.

Is 121.5 still monitored?

DOES ANYONE STILL MONITOR 121.5 MHZ ELTS? Even though satellites no longer monitor 121.5 MHz signals, the search and rescue community will still respond when notified through other means. ELTs were originally intended to use 121.5 MHz to inform air traffic control and pilots monitoring the frequency of an emergency.

What frequency do pilots use to talk to each other?

If you wish to talk to the pilot of another airplane, use the air-to-air frequency of 122.75 MHz. It is not considered good etiquette to fill other frequencies with pilot -to- pilot chats. VOR frequencies are between 108.0 and 117.975 MHz, immediately below aviation communication frequencies beginning at 118.0.

What does squawk mean in aviation?

A discrete transponder code (often called a squawk code) is assigned by air traffic controllers to identify an aircraft uniquely in a flight information region (FIR). This allows easy identification of aircraft on radar.

Is Flight Watch still active?

Traditionally the En Route Flight Advisory Service (EFAS)— Flight Watch —has been available anywhere in the U.S. on 122.0. The FAA will discontinue using 122.0 for both Flight Watch and Hi- Watch and make those services available on 122.2 and all remote communications outlet frequencies.

What is Unicom frequency used for?

UNICOM is a nongovernment air/ground radio communication station which may provide airport information at public use airports where there is no tower or FSS. On pilot request, UNICOM stations may provide pilots with weather information, wind direction, the recommended runway, or other necessary information.
