Oct 1, 2010 --- Flight Watch is the name for an Enroute Flight Advisory Service (EFAS) dedicated to providing weather to and collecting it from pilots operating at lower altitudes. While Flight Service (FSS) operates Flight Watch, Flight Watch does not provide a full range of FSS services such as filing flight plans, acquiring preflight weather briefings, providing NOTAMs, or picking up IFR clearances; instead, it is limited to the following:
- en route weather updates
- collection of pilot weather reports (PIREPS).
The service is available on a single common frequency, 122.0 MHz, to flights operating between 5,000 and 17,000 ft msl from 06:00 to 22:00 local time across the United States. Flight Watch may be available below 5,000 ft MSL, depending on terrain and the distance from the nearest station.
