On Canadian charts, the MEF is the highest obstacle in the quadrant plus either: Maximum Elevation Figure or MEF is the highest feature within an area. For example, if you have 100 inches of model railroad track and the train climbs one inch, then the grade is 1 percent. The pumper truck shown in the figure below is to deliver 1.5 ft/s to a maximum elevation of 60 ft above the hydrant. The MEF depicts the lowest altitude you can fly and still be assured to clear every obstacle within that quadrant. Maximum Elevation Figure or MEF is the highest feature within an area. maximum elevation figure A figure, shown in each quadrangle bounded by ticked graticule lines on aeronautical charts, which represents the height in thousands and hundreds of feet, above mean sea level, of the highest known natural or manmade feature in that quadrangle, plus suitable factors to allow for inaccuracy and incompleteness of the topographical heighting information. It is of interest to pilots, who want to be aware of the highest mountain peaks and tall towers nearby, so that they can fly above them to avoid controlled flight into terrain. For example, if the highest man-made obstacle within a sector is 2,250 feet msl, 100 feet would be added to cover a possible vertical error (2,350 feet).
