What is the base altitude of low level airways?

The base altitude of low-level airways is established at 2,200 feet above ground level (AGL). This altitude is defined by aviation regulations to provide a safe vertical separation between aircraft operating in these designated corridors and those traveling at lower altitudes, particularly in regions where terrain and other environmental factors can pose hazards.

Low-level airways are primarily used for flight navigation and are vital for ensuring that pilots have clear guidance and structure as they fly at lower altitudes, which is often necessary for departure, arrival, and training flights. Maintaining a consistent base altitude of 2,200 feet AGL helps in creating a standardized environment across various regions, supporting air traffic management and coordination.

The other altitude options do not represent the correct regulatory setup for low-level airways; they may correspond to different airspace classifications or operational requirements but do not specifically define the structured low-level airway system.
