What are the visibility and cloud clearance minimums for Class A airspace?

• A. 1 SM and clear of clouds
• B. 3 SM and clear of clouds
• C. N/A and N/A
• D. 3 SM and 1000' above

Answer: (C)

In Class A airspace, the requirements for visibility and cloud clearance are not applicable because Class A airspace is typically defined as airspace from 18,000 feet MSL (Mean Sea Level) up to 60,000 feet MSL, which is primarily used for IFR (Instrument Flight Rules) operations. Pilots operating in Class A airspace must be flying under IFR and following air traffic control instructions, which inherently assumes that they will maintain adequate visibility and separation from clouds through instrument flying. Since visual flight rules (VFR) weather minimums do not apply in Class A airspace, and because all flight operations must adhere to IFR standards, the visibility and cloud clearance requirements are indeed considered “N/A.” This means that specific visibility and cloud clearance minimums are not defined for this airspace, as it is designed for operations relying on instrument navigation rather than visual navigation.
