FINAL APPROACH POINT- The point, applicable only to a nonprecision approach with no depicted FAF (such as an on airport VOR), where the aircraft is established inbound on the final approach course from the procedure turn and where the final approach descent may be commenced. The FAP serves as the FAF and identifies the beginning of the final approach segment.

FINAL APPROACH SEGMENT-
(See SEGMENTS OF AN INSTRUMENT
APPROACH PROCEDURE.)
FINAL APPROACH SEGMENT [ICAO]-That segment of an instrument approach procedure in which alignment and descent for landing are accomplished.
FINAL CONTROLLER- The controller providing information and final approach guidance during PAR and ASR approaches utilizing radar equipment.
(See RADAR APPROACH.)
FINAL GUARD SERVICE- A value added service provided in conjunction with LAA/RAA only during periods of significant and fast changing weather conditions that may affect landing and takeoff operations.
FINAL MONITOR AID- A high resolution color display that is equipped with the controller alert system hardware/software which is used in the precision runway monitor (PRM) system. The display includes alert algorithms providing the target predictors, a color change alert when a target penetrates or is predicted to penetrate the no transgression zone (NTZ), a color change alert if the aircraft transponder becomes inoperative, synthe-sized voice alerts, digital mapping, and like features contained in the PRM system.
(See RADAR APPROACH.)
FINAL MONITOR CONTROLLER- Air Traffic Control Specialist assigned to radar monitor the flight path of aircraft during simultaneous parallel and simultaneous close parallel ILS approach operations. Each runway is assigned a final monitor controller during simultaneous parallel and simulta-neous close parallel ILS approaches. Final monitor controllers shall utilize the Precision Runway Monitor (PRM) system during simultaneous close parallel ILS approaches.

(See FLIGHT INFORMATION REGION.)
FIRST TIER CENTER- The ARTCC immediately adjacent to the impacted center.
FIX- A geographical position determined by visual reference to the surface, by reference to one or more radio NAVAIDs, by celestial plotting, or by another navigational device.
FIX BALANCING- A process whereby aircraft are evenly distributed over several available arrival fixes reducing delays and controller workload.
FLAG- A warning device incorporated in certain airborne navigation and flight instruments indicating that:
a..
Instruments are inoperative or otherwise not operating satisfactorily, or
b..
Signal strength or quality of the received signal falls below acceptable values.
