FAA Part 107 Drone Practice Test

What is the altitude limit for Class A airspace?

1. Above 10,000 feet MSL

2. At surface level

3. Between 3,000 and 8,000 feet

4. 18,000 feet and above

The correct answer is: 18,000 feet and above

The altitude limit for Class A airspace is specifically established at 18,000 feet and above, measured in feet Mean Sea Level (MSL). This class of airspace is regulated to ensure safe and efficient management of high-altitude operations, primarily for commercial airline traffic and the operation of other aircraft under Instrument Flight Rules (IFR). Class A airspace is designed to provide a controlled environment where all operations are conducted under the purview of air traffic control and all aircraft must comply with IFR; this assists in maintaining safe separation between numerous aircraft flying at high altitudes. The other options provided do not accurately reflect the defined boundaries of Class A airspace, reinforcing the importance of understanding these regulations for safe drone operation and awareness in relation to manned aviation.
