What does MEA stand for?

• A. Mean Elevation Altitude
• B. Maximum Enroute Altitude
• C. Mandatory Elevation Altitude
• D. Minimum Enroute Altitude

Answer: (D)

Minimum Enroute Altitude is the lowest published altitude on an IFR enroute segment that guarantees obstacle clearance and reliable navigation signal reception along the route. When flying, you should remain at or above this altitude on that segment unless ATC clears you to a lower altitude or you need to descend for weather or other reasons. For contrast, Minimum Obstacle Clearance Altitude also provides obstacle clearance but only guarantees nav signal reception within 100 nautical miles of a NAVAID. The other terms listed aren’t used in this context.
