What type of airspace requires a Remote Pilot to obtain permission prior to flight?

A Remote Pilot must obtain permission prior to flight in Class B, C, D, and E airspace because these classifications indicate areas where air traffic control (ATC) has jurisdiction and where the operational rules are more stringent to ensure the safety of manned aircraft. Class B airspace, typically surrounding major airports, requires a specific clearance from ATC due to its heavy traffic load. Class C and D airspace also require communication with ATC, although the requirements are less stringent than in Class B.

Class E airspace, which is often used for the transition to and from Class A airspace, requires adherence to certain communication and operational protocols, especially when flying at altitudes where manned aircraft are accustomed to operating. In these airspaces, remote pilots must follow ATC instructions and ensure they are compliant with any special requirements, such as visibility and distance from clouds.

In contrast, Class G airspace is uncontrolled airspace with fewer operational restrictions, where a Remote Pilot typically does not need to obtain permission before flying, provided they adhere to basic visual flight rules. Class A airspace is reserved for high-altitude operations (over 18,000 feet) and is subject to strict ATC regulations; however, remote operations at these alt
