What is the definition of a holding fix?

A holding fix is defined as a specified fix that is identified by navigational aids (NAVAIDs) or visual references to the ground. This concept is essential in air traffic control and flight operations because it provides pilots and controllers with a clear point to establish a holding pattern. Holding patterns are used to manage air traffic flow, especially in situations where aircraft must wait for clearance to land or proceed to their next destination.

The designation of a holding fix ensures that all parties—pilots and air traffic controllers—are on the same page regarding the aircraft's location during the holding phase. Whether using electronic navigation systems or visual markers, identifying the fix allows for precise navigation and effective management of airspace.
