Which airspace class requires ATC clearance for all aircraft, both IFR and VFR?
Answer: Class A
Class A airspace, from 18,000 feet MSL to FL600, requires ATC clearance and IFR flight rules for all aircraft.
What is the vertical limit of Class A airspace in the contiguous United States?
Answer: 18,000 ft MSL to FL600
Class A airspace extends from 18,000 feet MSL up to and including FL600 over the contiguous US.
Class B airspace is typically associated with which type of airport?
Answer: Busiest commercial service airports
Class B airspace surrounds the nation's busiest commercial service airports and requires ATC clearance for all operations.
What communication requirement exists for aircraft operating in Class D airspace?
Answer: Two-way radio contact before entering
Aircraft must establish two-way radio communication with ATC before entering Class D airspace.
What is the upper limit of Class G (uncontrolled) airspace when it underlies Class E airspace that begins at 1,200 ft AGL?
Answer: 1,200 ft AGL
Class G airspace extends from the surface up to but not including the base of overlying Class E airspace, in this case 1,200 ft AGL.
Which airspace class uses a Mode C transponder as a requirement for VFR aircraft operating above 10,000 ft MSL?
Answer: All airspace above 10,000 ft MSL
FAR 91.215 requires a transponder with altitude reporting (Mode C) for all aircraft operating above 10,000 ft MSL MSL, excluding Class A.
