What does AGL stand for?

What does AGL stand for?

• A. Above Geodetic Level
• B. Above Ground Level
• C. Above Ground Height
• D. Above Ground Line

Answer: (B)

AGL is a height reference used in aviation that indicates how high something is above the ground directly beneath it. It stands for Above Ground Level, which is the altitude relative to the terrain under the aircraft. This matters because the same absolute height above sea level can represent very different heights above the ground in areas with hills or mountains, so AGL provides a terrain-relevant measure for things like obstacle clearance and pattern altitudes near airports. The other phrases aren’t standard aviation terms, so they aren’t used to describe how high an object or aircraft is relative to the surface.
