MEA stands for which term?

• A. Minimum enroute altitude
• B. Minimum safe altitude
• C. Minimum crossing altitude
• D. Minimum obstruction clearance altitude

Answer: (A)

Minimum enroute altitude is the lowest published altitude along an IFR enroute segment that ensures obstacle clearance and reliable navigation signal reception for the route. Flying at or above this altitude keeps you clear of terrain or obstacles and lets you receive the required navigation aid signals to stay on course between fixes. Other concepts refer to different situations: a minimum safe altitude is a broader figure used for emergency planning and general regional clearance, not specific to a segment’s navigation signals; a minimum crossing altitude is the altitude you must be at when crossing a fix to ensure a safe transition to the next segment; a minimum obstruction clearance altitude provides obstacle clearance but only guarantees reception of a navigation signal within a certain distance of the guiding VOR, not everywhere along the route.
