Definition
A waypoint depicted on an instrument approach chart that defines the point at which the pilot must begin the published missed approach procedure if a landing cannot be made. On RNAV (GPS) approaches, it is shown on the plan view with a specific symbol and is the point where the GPS automatically sequences from approach guidance to missed approach guidance.
Plain English
It is the spot on the approach where, if you cannot land, you stop trying to land and start flying the published go-around route instead.
Context Anchor
Seen in the plan view of instrument approach charts, especially RNAV and GPS approaches.
Derivation
Waypoint means a point along a route used for navigation. Missed approach means the planned procedure flown when an approach cannot safely continue to landing. Together, the phrase means the navigation point tied to starting that missed approach.
Why Pilots Care
It tells the pilot exactly where to begin the missed approach procedure so terrain clearance and routing back to a hold or alternate are assured.
Intuition Check
This does not mean a waypoint the pilot failed to fly over. It means the waypoint that marks where the missed approach decision and procedure begin.
Example Sentence 1
Unable to see the runway at minimums, the pilot continued to the missed approach waypoint and then began the published climb and turn.
Example Sentence 2
The GPS sequences to the missed approach waypoint after passing the final approach fix on the approach.
