Minimum En Route Altitude (MEA)
The Minimum En Route Altitude (MEA) is the minimum altitude published on flight maps between two navigation fixes, which guarantees sufficient signal coverage for safe navigation and allows clearance over any obstacles in the way. The MEA is the highest altitude that ensures adequate signal coverage of the radio communications and navigation equipment, which helps to ensure safe navigation between air traffic control fixes. This altitude also meets the requirements for obstacle clearance. It is important to maintain this altitude for the safe and efficient operation of aircraft. Failure to maintain the minimum en route altitude can result in an increased risk of collision with other aircraft or terrain. The MEA is essential for pilots to navigate safely and maintain the appropriate distance within their flight path.
