Aviation Issues: Flight Watch Services Now on 122.2 MHz

As of Sept. 24, flight crews should use the flight service common frequency of 122.2 MHz for flight watch services that were formerly available on 122.0 MHz and Emergency Flight Advisory Service (EFAS), more commonly known as “Flight Watch.” The change means that most pilots will utilize a single frequency for access to all enroute flight services. This change is a significant move toward further consolidation of flight advisory services in the United States.

Lockheed Martin Flight Service, the company that operates the U.S. flight service states (FSS) on behalf of the FAA, will continue monitoring 122.0 and high-altitude EFAS frequencies throughout a six-month transition period, thus enabling pilots time to adjust to the new procedures.
