Drone Pilot Practice Exam

Class A airspace is indeed characterized by a controlled environment that mandates communication with Air Traffic Control (ATC). This airspace extends from 18,000 feet MSL (mean sea level) up to and including FL600 (flight level 600, or 60,000 feet), where all flights must operate under Instrument Flight Rules (IFR). Pilots must obtain clearances from ATC before entering this airspace, ensuring safe and organized flight operations through regulation and communication. The stringent requirements for Class A airspace are in place to manage high-volume traffic, maintain separation between aircraft, and enhance safety in an environment where various aircraft operate at high altitudes and speeds.

In contrast, Class G airspace is uncontrolled and does not require ATC communication. Class E airspace generally allows for some level of flight operations without direct ATC communication, especially when it is not in the vicinity of an airport. Class C airspace requires communication with ATC, but it is specific to airspace around airport operations, which is different from the expansive and uniformly managed Class A airspace.
