Definition
An air traffic controller assigned to monitor only the final approach course of aircraft conducting simultaneous parallel ILS approaches to closely spaced parallel runways. The Final Monitor Controller has override authority over the previously assigned approach control frequency and can issue breakout instructions to maintain separation if an aircraft strays toward the No Transgression Zone between the two final approach courses.
Plain English
A controller whose only job is to watch aircraft on final approach when two planes are landing on parallel runways at the same time, ready to step in and tell a pilot to turn away if either aircraft drifts too close to the other.
Context Anchor
Seen in ATC and AIM discussions of simultaneous approaches to parallel runways, especially at busy airports where aircraft may be landing on nearby runways at the same time.
Derivation
‘Monitor’ comes from the Latin ‘monere,’ meaning to warn or remind. The role exists to warn pilots the moment something starts to go wrong on final approach — the controller’s sole purpose is watching and warning, not sequencing or routing.
Why Pilots Care
Adds an independent safety layer during the critical final approach phase by catching course or altitude errors before they become dangerous.
Intuition Check
Do not read “final” as meaning the last controller you will talk to. Here it means the final part of the approach to the runway. Do not read “monitor” as passive watching. This controller can issue urgent instructions to keep aircraft safely apart.
Example Sentence 1
During the simultaneous ILS approaches to runways 26L and 26R, the Final Monitor Controller issued an immediate breakout to the aircraft on the left approach when it began drifting toward the centerline.
Example Sentence 2
During simultaneous ILS approaches the final monitor controller maintained continuous radar watch on each aircraft until touchdown.
