Which airspace class typically requires ATC communication but is less regulated than Class A?

• A. Class G
• B. Class D
• C. Class C
• D. Class E

Answer: (C)

Class E airspace is the correct answer, as it typically requires ATC communication under specific conditions but is less regulated than Class A airspace. Class E airspace serves to provide a controlled environment for aircraft operations, particularly at lower altitudes, without the stringent requirements associated with Class A. In Class E airspace, VFR (Visual Flight Rules) operations are permitted when certain visibility and cloud clearance criteria are met. Pilots operating in this airspace are generally required to establish communication with Air Traffic Control (ATC) when flying under Instrument Flight Rules (IFR) or when transitioning to or from airspace that requires communication. The distinction from Class A is significant; Class A airspace is structured to encompass high-altitude operations and requires all flights to be conducted under IFR, with constant ATC communication. Thus, Class E provides a balance of controlled airspace where greater flexibility is allowed for pilots compared to the more rigid regulations found in Class A.
