What does MEA stand for in aviation context?

In an aviation context, MEA stands for Minimum Enroute Altitude. This term is crucial for pilots as it indicates the lowest altitude that an aircraft can fly along a specific route segment while ensuring adequate obstacle clearance and receiving reliable navigation signals.

The MEA is designed to maintain safety during flight by providing a buffer above the terrain and obstacles, thus preventing potential collisions. It takes into account the highest terrain within a defined sector and allows for the safe operation of aircraft while also ensuring that they remain in navigable airspace.

Choosing this option reflects an understanding of airspace management and safety regulations, as pilots must adhere to these altitudes to comply with legal and safety standards established by aviation authorities.
