Flight watch information is also a great way to verify or disprove the forecasts that you ve heard during a preflight briefing. So, think of flight watch as an early warning system. Flight watch is a great source of current radar information, too. Flight watch specialists have access to some of the latest-generation weather radar imagery. Let s say that you want a full route briefing while en route.
Flight watch is no good for that, but there is an alternative.
For prolonged sessions with a flight service station briefer, you can call up FSSs on their published frequencies. These can be found above VOR frequency identification boxes on aeronautical charts. Often, these frequencies are either 122.2, 122.4, or 122.6 MHz although other frequency designations are certainly possible. Again, remember that flight service specialists talk and listen on many different frequencies, and that some of those simplex frequencies are co-located with VOR frequencies. Then it starts to run, over and over.
