Question: 1 / 400

Which of the following best defines MOCA?

Minimum operating clearance altitude

Minimum obstacle clearance altitude

The definition of MOCA, or Minimum Obstacle Clearance Altitude, is essential for ensuring safe navigation and flight operations in the presence of terrain and obstacles. MOCA provides the lowest altitude at which an aircraft can fly while still maintaining sufficient clearance from any obstacles in the area, ensuring that there is a safety buffer above the highest terrain or obstacles.

This altitude is particularly important in areas where navigation aids are used, as it enhances safety by giving pilots and air traffic controllers confidence that the aircraft will not encounter unexpected obstacles during flight.

Understanding MOCA is crucial for flight planning and operational safety, as it helps to prevent accidents and enhances overall situational awareness during both normal operations and emergencies.
