Definition
A published track that aligns the aircraft with the runway during the final segment of an instrument approach. It may be defined by a localizer, an ILS, a final approach radial from a VOR, a bearing to or from an NDB, or an RNAV final approach track. It is a course (a direction of travel), not a physical line in space, and it does not include extensions beyond the final approach fix.
Plain English
The straight-in path you fly toward the runway during the last part of an instrument approach.
Context Anchor
Seen on instrument approach charts and heard in approach clearances when a pilot is being guided to join or follow the final path toward landing.
Derivation
“Final” comes from a word meaning “last” or “at the end.” “Course” in navigation means the path or direction to be followed, not a classroom subject. Together, the phrase points to the last defined path toward the runway during an approach.
Why Pilots Care
Staying precisely on the final approach course keeps the aircraft aligned with the runway and clear of terrain; even small deviations can trigger a missed approach or unsafe landing.
Intuition Check
Do not read “course” as a lesson or subject here. In this phrase, “course” means the path or line the aircraft is supposed to follow toward the runway.
Example Sentence 1
Approach control cleared us to intercept the final approach course at SAGES and report established.
Example Sentence 2
ATC cleared the aircraft to join the final approach course at the final approach fix.
