How do terrain maps assist pilots during navigation?

Terrain maps are an essential tool for pilots as they provide detailed information about the elevation of the land and any potential obstructions that could impact flight paths. When navigating, especially during takeoff and landing or while flying at lower altitudes, understanding the topography of the area is crucial.

These maps typically highlight features such as mountains, hills, valleys, and any man-made structures that may pose a risk to aircraft. Therefore, recognizing these elevation changes allows pilots to make informed decisions about their altitude and route selection, ensuring greater safety. Being aware of terrain helps in avoiding controlled flight into terrain (CFIT) accidents, which can occur when a pilot does not realize they are about to fly into rising ground or obstacles.

This utilization of terrain maps greatly enhances situational awareness and contributes to safer navigational practices, making them an indispensable resource for pilots in the en route phase of flight.
