What altitude does MOCA provide obstruction clearance above?

MOCA, or Minimum Obstacle Clearance Altitude, is designed to ensure that an aircraft maintains safe vertical separation from obstacles in the vicinity of an airway or route. The key aspect of MOCA is that it provides at least 1,000 feet of clearance above the highest obstacle within a 22 nautical mile radius of the course in areas outside of designated mountainous terrain.

This elevation is crucial for ensuring safety during navigation and flying, especially in mountainous or obstacle-rich environments. It allows pilots to operate confidently, knowing that they are sufficiently clear of potential hazards.

The other options present different altitude clearances, which do not align with the minimum requirements established for MOCA. Understanding MOCA's specific altitude provides an essential knowledge base for pilots, especially in terms of navigation and obstacle awareness during flight operations.
