What is standard Unicom frequency?

Originally, 122.8 MHz was the standard Unicom frequency for all airports. As flying activity and the number of airports increased, 122.7 MHz and 123.0 MHz were added to accommodate the increased traffic.

What is the frequency for international Unicom?

UNICOM (Universal Communications) is the VHF broadcast frequency, set to 122.800 MHz in IVAO, which is selected to send traffic information broadcast by aircraft (TIBA), named in IVAO as self announcing procedure for pilots.

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.

What is the meaning of Unicom?

A UNICOM (universal communications) station is an air-ground communication facility operated by a non-air traffic control private agency to provide advisory service at uncontrolled aerodromes and airports and to provide various non-flight services, such as requesting a taxi, even at towered airports.

Can a student fly into Bravo class?

Class B And Students Generally, student and recreational pilots are not permitted to fly in Class B airspace, or to take off or land at a Class B airport.

How do you tell if an airport is towered?

Two things distinguish a towered airport. One is the presence of air traffic controllers (ATC), whose primary function is to coordinate traffic flow and prevent collisions. The second is that a pilot must maintain two-way radio contact with ATC and obtain clearances to land, taxi, and take off.

What does Ctaf mean in aviation?

a. COMMON TRAFFIC ADVlSORY FREQUENCY ( CTAF ) – A designated frequency for the purpose of carrying out airport advisory practices while operating to or from an airport t t does not have a contrd tower or an airport where the contrd tower is not operational.

How do I find my Ctaf?

The CTAF is always identified by C / circle symbol, and the frequency always appears ‘before’ or to the ‘left’ of the circled C. The control tower frequency is identified by the letters CT and the frequency appears to the right of the letters.

What is a Ctaf R?

What are the aviation frequencies?

The VHF 108 to 136 MHz Civil Aviation Band

Frequencies llocation SLC Receiver Receivable
118.000- 136.000 MHz Aviation Communication (720 Channels) Yes
121.500 MHz Aviation Distress Yes
121.600 MHz Civil Air Patrol (Authorized use only) Yes
121.700 MHz Aviation Ground Control Yes


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.

What radio frequency do airplanes 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.
