4 - King - Airspace and Weather Minimums Flashcards
Class Alpha airspace is?
A is for Altitude
Above 18,000 MSL and including 60,000 feet.
including the airspace overlying the waters within 12 nautical miles of the coast

Towered airports with ATC
SFC (surface) to 10,000 (MSL)
ATC clearance is required for all aircraft.
Must have operable two-way radio to communicate with ATC.
The cloud clearance requirement for VFR operations is “clear of clouds”
Class Charlie airspace is?
