MEF is not the “the height of the highest feature within a quadrangle area,” although it is based on it. Per the Aeronautical Chart User’s Guide, this figure is calculated on the actual published height of the highest obstacle, adds potential error of 100 feet or 1/2 the contour, and then rounded up to the nearest 100 feet for manmade and 200 feet for natural obstacles. This question is addressed thoroughly by King Schools, and I challenged my checkride examiner, who also didn’t know the details.
Daryl,
Thanks for pointing that out. The example here refers to ForeFlight’s display of MEF in the app, which is defined in their Pilot’s Guide:
The Maximum Elevation Figure (MEF) is displayed for a half-degree latitude by half-degree longitude box centered on the aircraft location when moving at 40 knots or greater. Height MEF is calculated as: the tallest obstacle or terrain in that box, rounded up to the nearest 200 feet.
