What does Grid MORA stand for?

Grid MORA stands for Minimum Off Route Altitude. This term is important in aviation as it designates the lowest altitude that an aircraft can safely fly off of a designated route while ensuring terrain and obstructions are avoided. The MORA provides pilots with a safety buffer, particularly in areas where there may be a lack of coverage from air traffic services or in regions that may not have precise maps of all obstacles.

This altitude is determined based on the elevation of terrain and obstacles, calculated in specific grid areas. Understanding MORA is crucial for flight planning and navigation, as it helps to maintain a safe vertical consideration when flying outside standard flight paths, ensuring the safety of the aircraft and its occupants while minimizing the risk of collision with unmarked terrain or structures.
