What do Maximum Elevation Figures (MEF) indicate?

Maximum Elevation Figures (MEFs) are crucial for pilots as they represent the highest elevation within a given section of a charted area, typically expressed in feet above mean sea level. MEFs are designed to inform pilots of the highest terrain or obstacles in that area, ensuring they maintain safe altitudes while flying.

The significance of MEFs lies in their role in obstacle clearance; they help pilots avoid potential collisions with terrain and other obstructions. By using MEFs, pilots can better plan their flight routes, especially in mountainous or rugged areas where terrain may vary significantly.

Understanding MEFs is essential for navigation and maintaining safe flight operations, particularly in areas where obstacles might not be immediately visible or expected.
