Maximum Elevation Figure (MEF) Definition
The Maximum Elevation Figure (MEF) is a numerical value that is printed on aeronautical charts within each rectangular area, which is formed by the displayed lines of latitude and longitude. This value helps pilots to determine the highest known feature – such as a mountain or a tall building – in that particular space. The MEF provides the elevation of the highest known feature to the nearest higher hundred feet above the mean sea level. This information is critical for flight safety because it helps pilots to avoid potential obstacles or hazards that could affect their flight path. The MEF may be revised periodically as new data becomes available, and it is essential for pilots to keep these figures updated to ensure a safe and efficient flight. Overall, the Maximum Elevation Figure plays a vital role in aviation operations and helps pilots navigate through complex airspace with confidence.
