What type of frequency does ATC use?
All ATC communications are between 118.0 and 137.0 MHz. If you think you’re given a frequency above or below those numbers, there is a mistake.
What frequency do airlines use?
Most Common Aviation Frequencies and Allocations 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.
What is the purpose of Unicom?
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.

Do I use CTAF or UNICOM?
You call “Traffic” on the CTAF when you are self reporting your position. You are not soliciting of expecting a response. You are talking to other aircraft. You call “Unicom” when you are expecting a response from someone at a ground station.
When are ATC frequencies preset in air traffic control?
If a flight condition involves more than two different frequencies need in rapid succession, it can be hectic to set the radio. In the basic case, taking off or landing at a single airport, there is usually no problem. You might have two frequencies, tower and ground. Then, after you take off, you swap ground for ATC.
Where can I find the air traffic frequencies?
On the ground, you may find airline ground operations in the 460.65-460.9 MHz range. Often, you can learn of flight delays, cancellations, or gate changes on the 460 frequencies before they are announced. These frequencies are not listed at AirNav.
Are there national air traffic frequency allocations?
There are no official “national” company frequency allocations, however among larger airlines there are common frequencies that you will find used by each at many different airports.
When do pilots preset frequencies on the radio?
I’ve noticed that sometimes pilots tend to present the next ATC frequency in the standby radio, and when required to switch frequencies, they can just push the frequency transfer switch to switch the preset frequency to the active radio. When do pilots preset frequencies?
