What does MOCA stand for in aviation regulations?

MOCA stands for Minimum Obstacle Clearance Altitude in aviation regulations. This term is crucial as it refers to the lowest altitude that provides adequate obstacle clearance within a specified area, ensuring safety during flight operations. It helps pilots to maintain a safe altitude above terrain and obstacles when navigating through controlled airspace, especially in the absence of radar coverage. By following the MOCA, pilots can avoid potential collisions with obstacles while also ensuring compliance with air traffic regulations.

This designation is particularly important for approaches and departures in mountainous regions or areas with significant terrain elevation, where a clear understanding of minimum altitudes is essential for safe flying.
