What distinguishes a waypoint from a fix?

A waypoint is specifically defined as a geographic point used in navigation, which helps in guiding an aircraft along a route. These waypoints often appear in flight plans and are crucial for pilots to navigate through airspace, especially when utilizing instruments. On the other hand, a fix generally refers to a specific point in space used primarily for air traffic control reference. Fixes may signify a navigational location for reporting positions to ATC, or they can be locations for holding patterns, but they aren't necessarily made for guiding flight paths like waypoints.

This distinction is important in aviation as it offers clarity on how these points are used operationally. While both waypoints and fixes serve critical roles, understanding their specific applications enhances a pilot or aviation professional's navigation and communication capabilities.
