AGL

AGL (Above Ground Level) refers to the vertical distance that is measured between an aircraft and a particular land mass. This term is commonly used in aviation to determine the height of an aircraft in relation to the surface of the earth. It is an essential parameter used by pilots when flying aircraft, as it helps them to maintain safe altitudes when flying over terrain which can be hazardous to the aircraft. AGL measurements are taken by using instruments such as altimeters, which can calculate the aircraft’s height above the terrain by measuring air pressure. Overall, AGL plays a critical role in ensuring the safety of aviation operations, as it helps pilots to avoid collisions with buildings, mountains, and other obstacles that may be present on the ground.
