At what altitude should a pilot be cautious to ensure clearance in the maximum elevation figure?

The correct altitude for a pilot to be cautious about in relation to the Maximum Elevation Figure (MEF) is 3,200 feet MSL. The MEF represents the highest terrain or obstacle within a specific area on a sectional chart, plus a buffer of 100 feet for safety. This information is critical for pilots to ensure they maintain adequate clearance over any potential obstacles during flight.

By flying at or above the specified MEF altitude, pilots help minimize the risk of flying into obstacles such as towers, hills, or other structures that may not be prominently marked on charts. In this case, the altitude of 3,200 feet MSL aligns with the safety margins needed above the terrain and any potential obstructions in the area represented by the MEF.

Other altitudes may not adequately consider the specified safety margins set by the MEF, which takes into account the localized highest points along the flight route, thus posing a greater risk when flying below this altitude. This makes it essential for pilots to be aware of their altitude in relation to the MEF, ensuring safe navigation during flight operations.
