So my IR checkride is approaching, and the thing I'm the most sketchy
on I think is the weather charts. I'm fine with TAF, METAR, and other
textual, but I guess it's because I can't find all the exact same
graphics on DUATS/DUAT that they use on the FAA exam (prognostic
charts, etc). Even DUAT/DUATS show things slightly differently. How
much is this going to be asked about on the checkride? Should I know
every possible symbol for all those charts, or is getting a general
idea and then calling 800-WX-BRIEF good enough?
