Definition
An imaginary point used by air traffic control to vector aircraft onto the final approach course. It is located along the final approach course one nautical mile from the final approach fix on the side away from the airport, and no closer than five nautical miles from the landing threshold.
Plain English
A spot in the sky that controllers use as the aiming point when they turn an aircraft onto the line that leads straight in to the runway. It sits just outside the final approach fix, far enough from the runway to give the pilot room to get established before landing.
Context Anchor
Seen in instrument approach and air traffic control vectoring discussions, especially when controllers are turning aircraft onto final approach.
Derivation
Gate' is used here in the sense of a doorway or entry point — the place where the aircraft enters the final approach. It is not a physical structure; it is a defined point in space that marks the transition from being vectored to being established on the approach.
Why Pilots Care
It helps maintain safe spacing between aircraft and ensures proper alignment before final descent to the runway.
Intuition Check
Do not picture a physical gate, sign, or marker outside the aircraft. An Approach Gate is an invisible ATC planning point used to position the aircraft properly before final approach.
Example Sentence 1
Approach turned us onto final well outside the approach gate, giving us plenty of room to get established before the final approach fix.
Example Sentence 2
The pilot reported established on the approach by the time the aircraft reached the approach gate.
