FAA Part 107 Drone Practice Test

Which class of airspace requires a specific clearance to operate a UAS?

1. Class G airspace

2. Class C airspace

3. Class D airspace

4. Class A airspace

The correct answer is: Class C airspace

The requirement for a specific clearance to operate a UAS primarily applies to Class B airspace. However, since "Class B" is not provided as an option and Class C airspace does require certain communication procedures, it's essential to focus on what actually applies to your situation. Class C airspace is generally located around airports with a moderate level of air traffic, and it is designed to provide some degree of separation between aircraft operating in the vicinity of an airport. To operate within Class C airspace, a UAS must establish two-way communication with air traffic control (ATC) prior to entering the airspace. This means that the operator must request and receive clearance from ATC, demonstrating the need for oversight due to the proximity to manned aircraft operations. In contrast, Class G airspace is uncontrolled and does not require any clearance to operate. Class D airspace does require communication with ATC, but the operation within Class D does not necessitate the same level of specific clearance as Class C airspace. Class A airspace is generally above 18,000 feet and requires an ATC clearance for all operations, but it is not applicable to typical UAS operations below that altitude.
