How do I find my Unicom frequency?

1. Communicate with UNICOM station on published CTAF frequency (122.7; 122.8; 122.725; 122.975; or 123.0). If unable to contact UNICOM station, use self‐announce procedures on CTAF….Section 1. Services Available to Pilots.

Use Frequency
Helicopter air-to-air communications; air traffic control operations. 123.025

What frequency is UNICOM?

(d) At airports which have no control tower, RCO, flight service station or unicom, the frequency 122.900 MHz is available for assignment to aeronautical utility stations.

How many UNICOM frequencies does an airport use?

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 common frequency for flight service?

122.2 MHz
The primary source is from a flight service station (FSS), and all stations answer the common frequency 122.2 MHz.

Is CTAF the same as UNICOM?

COMMON TRAFFIC ADVISORY FREQUENCY (CTAF)− A frequency designed for the purpose of carrying out airport advisory practices while operating to or from an airport without an operating control tower. The CTAF may be a UNICOM, Multicom, FSS, or tower frequency and is identified in appropriate aeronautical publications.

What is UNICOM vs CTAF?

UNICOM is a licensed non-government base station that provides air-to-ground and ground-to-air communication, and may also serve as a CTAF when in operation. MULTICOM is a frequency allocation without a physical base station that is reserved as a CTAF for airports without other facilities.

What is a CTAF frequency used for?

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.

Do you use CTAF or Unicom when tower is closed?

At nontowered airports, the CTAF will normally be the designated unicom frequency. However, at an airport that has a part-time tower, the CTAF will normally become the tower frequency after the tower closes.

Are aviation frequencies AM or FM?

Amplitude modulation is one way of transmitting radio signals across large distances. While FM has many advantages, AM is typically used in aviation. The reason for this is the capture effect.
