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.

[clarification needed] In the US, the Federal Aviation Administration issues sectional charts.

Each quadrangle has its MEF printed in it in thousands and hundreds of feet above mean sea level.

Pilots are also required to ensure their planned route does not contravene the minimum flying altitude regulations contained in CAR 167.

LSALT may be determined in a number of ways as explained in the Australian Aeronautical Information Publication or AIP.
