Which of the following represents the abbreviation AGL?

AGL stands for "Above Ground Level," which is a critical term used in aviation and drone operations. It refers to the altitude of an object or aircraft relative to the ground directly beneath it. This measurement is essential for ensuring safe flight operations, especially when considering obstacles and regulations regarding minimum separation distances from structures and terrain.

Understanding AGL is vital for drone pilots as it directly impacts flight planning, altitude restrictions, and situational awareness during operations. Pilots need to differentiate between AGL and other altitude measurements, such as MSL (Mean Sea Level), which can lead to confusion if not properly understood. In essence, being aware of AGL helps pilots maintain safe operational heights above the ground and enhances the overall safety of their flight missions.
