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

The term "waypoint" refers to a predefined geographical location used for navigation. Waypoints are critical components in the aviation navigation system as they provide pilots with specific points along a flight route, allowing for precise navigation over long distances. These locations are usually defined by specific coordinates (latitude and longitude) and can be used to guide aircraft safely through various phases of flight, including departure, en route, and arrival.

Waypoints can be part of airways which are established routes that pilots follow, helping to ensure safe separation between aircraft in the airspace. They can also be used in conjunction with GPS technology, allowing for even more precise navigation. Overall, waypoints enhance situational awareness and improve the efficiency of flight operations.
