In my Experience
In my experience, as an FAA Designated Pilot Examiner testing Private Pilot applicants, I have come to the conclusion that most flight instructors are not teaching MOAs and Restricted Areas with the proper perspective. While most applicants can tell me technically about how MOAs and Restricted Areas behave, the tone of their voice conveys the conclusion that as a practical matter they would never, ever, think about calling to see if a Restricted Area is hot. They will always go around, as if the Restricted Area was actually a Prohibited Area. This is a very wasteful attitude as most Restricted Areas are, in fact, in use for only a few hours each day. The rest of the time you can fly right through if you would only take 15 seconds or so to make the call to the controlling agency. Now that names and frequencies are available on sectional charts, calling is a piece of cake.
