What does AGL stand for in aviation terminology?

AGL stands for "Above Ground Level" in aviation terminology. This measurement is significant because it provides pilots and air traffic control with a clear understanding of altitude in relation to the terrain or obstacles around an aircraft. AGL is distinct from other altitude measurements, such as Mean Sea Level (MSL), because it specifically indicates how high an aircraft is flying above the ground itself, which is crucial for ensuring safe navigation, takeoffs, and landings. Understanding AGL helps pilots avoid obstacles, maintain safe clearance from the ground, and adhere to regulations regarding minimum safe altitudes.
