What type of airspace does NOT require special permission for drone flight?

Class G airspace is the type of airspace that does not require special permission for drone flight. This airspace is classified as uncontrolled, meaning that it is not subject to the same regulations or air traffic control requirements as the controlled airspaces, such as Class A, B, or C.

In Class G airspace, drone operators can generally fly without needing to communicate with air traffic control, provided they adhere to the basic operational rules set forth by the FAA, such as keeping the drone within visual line of sight and below 400 feet in altitude. This makes Class G the most accessible airspace for recreational and commercial drone operators.

Class A, B, and C airspaces, on the other hand, have specific requirements regarding communication, permission, and often require pilots to possess certain certifications or to have an authorization to operate within those airspaces. Class A airspace is primarily for high-altitude operations and is strictly regulated, while Classes B and C involve more complex interactions with air traffic, especially near busy airports.
