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 standard Unicom frequency?

Originally, 122.8 MHz was the standard Unicom frequency for all airports. AOPA successfully lobbied for additional frequencies when this change took place. Four more Unicom frequencies became available: 122.725 MHz, 122.975 MHz, 123.050 MHz, and 123.075 MHz.

What is the difference between UNICOM and CTAF?

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.

What frequency does CTAF use?

The most common CTAF frequency is 126.7 MHz at non-towered aerodromes, except for when two CTAF airports are near each other. Aerodromes using CTAF outside tower hours typically nominate a frequency that is used during tower hours.

What is an aeronautical advisory station?

Aeronautical advisory stations, also called Unicom stations, are land stations used for advising pilots of private aircraft about local airport conditions. Aviation support stations are airborne and ground stations used for pilot training, soaring (with gliders), or free ballooning.

What is the meaning 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 you get weather from UNICOM?

AUTOMATED UNICOM – Provides completely automated weather, radio check capability and airport advisory information on an Automated UNICOM system. These systems offer a variety of features, typically selectable by microphone clicks, on the UNICOM frequency.

What is Unicom frequency Vatsim?

Unicom is a communication frequency set at 122.800MHz, where you can talk to other pilots and send them information about your positioning and intentions. It is mainly used for information purposes, and you can’t use it as a normal ATC frequency as there is no controller.

What is the emergency frequency on VHF band?

The universally-accepted, global distress frequency for any emergency radio transmission is VHF Channel 16 (156.800 MHz). If you have absolutely no clue what emergency frequency to try – and if scanning provides no transmissions – then keying into this frequency is your best option.

Can a student pilot request special VFR?

Student, Sport and Recreational Pilots may not request Special VFR clearances. Note that typically only one aircraft may operate under a Special VFR clearance at a time in the class B airspace, and ATC reserves the right to deny Special VFR depending upon workload or other operational considerations.

What is Multicom used for?

In U.S. and Canadian aviation, MULTICOM is a frequency allocation used as a Common Traffic Advisory Frequency (CTAF) by aircraft near airports where no air traffic control is available. Frequency allocations vary from region to region.

Is CTAF required?

While the FAA highly encourages radio reports over Common Traffic Advisory Frequencies (CTAF) published for non-towered airports, there is no legal requirement for it.

How do you read a 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.

When outbound from an airport without a Unicom station a tower or a flight service station FSS The pilot should self announce on frequency?

Leaving the runway. 2. No Tower, FSS, or UNICOM Self-announce on MULTICOM frequency 122.9. Before taxiing and before taxiing on the runway for departure.
