Definition
A specified geographical point used as the reference around which an aircraft flies a holding pattern. The fix is identified on charts and may be defined by a navaid, an intersection of radials or bearings, a DME distance, or a GPS waypoint.
Plain English
A fixed point in the sky that a pilot uses as the anchor for flying a holding pattern. The aircraft flies a racetrack-shaped loop that always passes back over this point.
Context Anchor
Seen on instrument clearances, approach charts, and ATC instructions when an aircraft is told to hold at a named point.
Derivation
‘Fix’ comes from the idea of fixing or pinning down a position — a known, identifiable spot. Adding ‘holding’ tells you what that fixed point is being used for: the reference for the holding pattern.
Why Pilots Care
Knowing the precise holding fix keeps the aircraft inside protected airspace, maintains separation from other traffic, and ensures compliance with ATC instructions.
Grounding Statement
Picture the holding pattern as a racetrack shape in the sky, with the Holding FIX as the known point that the whole pattern is tied to.
Intuition Check
Fix does not mean repair here. In aviation navigation, a fix is a known position; a Holding FIX is the known position used as the anchor for the hold.
Example Sentence 1
ATC cleared us to hold east of the LIBBY intersection, making LIBBY our holding fix.
Example Sentence 2
ATC cleared the flight direct to the holding fix at 5,000 feet to await approach sequencing.
