Airspace Class A Alfa AirspaceWhat is Class Alfa Airspace? The airspace from 18000 feet MSL up to and including FL600. FL600 is equivalent of 60000 feet MSL, so unless you are an astronaut or flying some type of super aircraft in the Air Force you will probably not fly above class Alfa airspace.
To fly in class A airspace you need to be at least a private pilot with an instrument rating.
You need to be on an active IFR flight plan, and you need to have a two-way radio capable of communicating with ATC.A Mode C altitude encoding transponder.
And you need to have the navigational instruments required for the specific IFR operations you may encounter on your filed IFR flight plan.
If you look on an aeronautical chart for class A airspace, you can stop.
Because Class A airspace is not specifically charted, you just have to know that above 18000 feet MSL class A airspace starts.
