Drone Pilot Practice Exam

Which class of airspace requires ATC authorization for all operations?

1. Class B airspace

2. Class G airspace

3. Class E airspace

4. Class D airspace

The correct answer is: Class B airspace

Class B airspace requires ATC (Air Traffic Control) authorization for all operations. This class of airspace is generally located around major airports and is the most restrictive. It is designed to provide a high level of safety for both commercial and general aviation traffic, as it contains a significant volume of aircraft operating within it. In Class B, all aircraft must receive permission from ATC before operating within this airspace, ensuring that traffic management is effectively coordinated. The ATC is responsible for providing separation between aircraft to prevent collisions, which is crucial given the density of traffic commonly found in these areas. In contrast, Class G airspace is uncontrolled and does not require ATC authorization for operations; pilots can operate freely without ATC clearance. Class E airspace, while somewhat regulated, also typically does not require clearance at lower altitudes and is mainly controlled at the higher levels. Class D airspace requires ATC communication, but not necessarily authorization for all operations, as certain VFR (Visual Flight Rules) operations may occur without specific permission. Overall, the distinct requirement for ATC authorization in Class B airspace distinguishes it as the most controlled and monitored airspace category.
