In aviation terminology, MEA stands for Minimum Enroute Altitude. This is a critical altitude that ensures safe navigation and obstacle clearance during flight. The MEA provides pilots with information about the lowest altitude that can be flown between two navigational points while maintaining sufficient clearance above terrain and obstacles. It takes into account various factors such as terrain elevation, potential obstructions, and the required signal coverage from navigational aids.

Understanding the MEA is essential for pilots, particularly when flying under instrument flight rules (IFR). If a pilot is unable to maintain the MEA, they may encounter unnecessary risk due to inadequate altitude in relation to terrain or obstacles. The MEA is specifically designed to enhance safety and operational efficiency during enroute phases of flight.
