Definition
The waypoint on a GPS or RNAV instrument approach that marks the beginning of the final approach segment, where the aircraft transitions from the intermediate segment and begins its descent toward the runway along the published final approach course.
Plain English
A specific point on a GPS approach where the final straight-in descent toward the runway officially begins.
Context Anchor
Seen on instrument approach charts and in aircraft navigation systems during area-navigation approaches.
Derivation
Waypoint is a navigation term meaning a defined point along a route, identified by latitude and longitude rather than a physical ground station. 'Final approach' names the last segment of an instrument approach. Together: the point where the final approach segment begins.
Why Pilots Care
It signals the start of the final descent and alignment phase, ensuring proper obstacle clearance and procedural compliance.
Intuition Check
Do not read “final” as meaning the last point before landing. A Final Approach Waypoint usually marks the start of the final part of the instrument approach, not the runway itself.
Example Sentence 1
Crossing the final approach waypoint, the pilot began the descent to the minimum descent altitude.
Example Sentence 2
Pilots must be established on the final course before reaching the final approach waypoint on an RNAV procedure.
