FAR 91.155 sets different VFR weather minimums for each airspace class - knowing the logic behind each number makes the table far easier to apply in actual flight.
Learn when and how to execute an in-flight diversion - the judgment-based skill the ACS tests and that separates safe cross-country pilots from accident statistics.
Class E airspace covers most of the continental U.S., but its shifting floor - from the surface to 14,500 ft MSL - trips up students on written tests, oral exams, and real flights.
The dashed magenta ring on a sectional chart marks Class E surface airspace at non-towered airports, raising VFR minimums from 1 mile to 3 miles visibility.
Class E airspace has a variable floor - 1,200 AGL, 700 AGL, or the surface - and where it begins determines which VFR weather minimums apply to your flight.
