What is the altitude range of Class A airspace?

• A. Below 18,000 ft MSL
• B. 18,000 ft MSL up to and including FL600
• C. Above FL600 only
• D. Up to 10,000 ft MSL

Answer: (B)

Class A airspace is defined by the Federal Aviation Administration (FAA) as the airspace from 18,000 feet Mean Sea Level (MSL) up to and including Flight Level 600 (FL600). This designation is essential for ensuring that high-altitude operations are conducted within a controlled environment, where air traffic control (ATC) provides services to all aircraft operating in this space. Aircraft operating in Class A airspace must be on an active instrument flight plan and must be receiving air traffic control services. This structured approach helps maintain safe separation between aircraft at higher altitudes where the volume of traffic can be significant. Knowing this range is crucial for pilots as they navigate and plan their flights, ensuring compliance with relevant regulations governing high-altitude operations. The other options refer to incorrect altitude ranges that do not correspond to the defined limits of Class A airspace, which is specifically focused on the airspace above 18,000 feet.
