- Acronym in English: AGL
- Nota adicional2
- When an aircraft is required to fly at a certain height above ground level, the AGL refers to its average height above terrain, not above certain high features and obstacles that may be in the area of operation. If the aircraft is to fly at a fixed height above all obstacles and features, then the height is above obstruction level (AOL), not above ground level. The former may be greater than or equal to the AGL.
