In navigation, what does the term "waypoint" refer to?

The term "waypoint" in navigation specifically refers to a designated, specific geographic location that is used as a reference point for pilots navigating their aircraft. Waypoints are critical in both visual flight rules (VFR) and instrument flight rules (IFR) as they serve as predetermined coordinates that help pilots to follow a clear route. These points are stored in navigation systems and can be used to assist with en route navigation, allowing pilots to execute flight plans efficiently and accurately.

Waypoints can be created using GPS coordinates, and they play an essential role in route planning and air traffic management. They help define the direction a flight should take and are often marked on charts, making navigation simpler and more accurate. In modern aviation, waypoints significantly enhance situational awareness for pilots and minimize the likelihood of navigational errors.
