VFR stamp is a time-saver--no need for a full brief for experienced pilots.

Action sequence:

        Starts with a DD-175.

        Forecaster enters the initial data into a dash-1 program which is part of a suite of programs in MIDDS.

        Forecaster looks at route including destination and alternatives.

        Forecaster considers whether or not to adjust local forecasts.

        Considers whether or not they can fly the route and what they will encounter along the way.

        Fill in the rest of the dash-1.


What supports the action sequence?

What is the needed information?

CONTEL Meteorological Workstation provides forecasts from any station in the US--DOD, NWS, airports.

Dash-1 program and sat, radar, warnings - all the usual stuff.

NOTE: Flight Weather Briefer is only good for canned routes (not to prepare the dash-1s).


Local and non-local observations, forecasts, warnings, pilot reports sent via CONTEL Meteorological Workstation.




What is good or useful about the support and the depiction of needed information?


        Most of the data is pretty easy to access - all in windows. It is easy to scroll through


What about the support or information depiction makes the action sequence difficult?


        One has to send a request to a station every time you use it--causes time delay.

        If the information is not timely, if the flow of data is stopped or reduced, it takes longer to do the job.

        There is lots of information on a dash-1.
