8/15/19  Pilot/Controller Glossary  FINAL APPROACH FIX- The fix from which the  final approach (IFR) to an airport is executed and  which identifies the beginning of the final approach  segment. It is designated on Government charts by  the Maltese Cross symbol for nonprecision  approaches and the lightning bolt symbol,  designating the PFAF, for precision approaches; or  when ATC directs a lower-than-published  glideslope/path or vertical path intercept altitude, it is  the resultant actual point of the glideslope/path or  vertical path intercept.  (See FINAL APPROACH POINT.)  (See GLIDESLOPE INTERCEPT ALTITUDE.)  (See SEGMENTS OF AN INSTRUMENT  APPROACH PROCEDURE.)  FINAL APPROACH-IFR- The flight path of an  aircraft which is inbound to an airport on a final  instrument approach course, beginning at the final  approach fix or point and extending to the airport or  the point where a circle-to-land maneuver or a missed  approach is executed.  (See FINAL APPROACH COURSE.)  (See FINAL APPROACH FIX.)  (See FINAL APPROACH POINT.)  (See SEGMENTS OF AN INSTRUMENT  APPROACH PROCEDURE.)  (See ICAO term FINAL APPROACH.)  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.  (See FINAL APPROACH FIX.)  (See SEGMENTS OF AN INSTRUMENT  APPROACH PROCEDURE.)  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 used to monitor the no  transgression zone (NTZ) during simultaneous  parallel approach operations. 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), synthesized voice alerts, and digital mapping.  (See RADAR APPROACH.)  FINAL MONITOR CONTROLLER- Air Traffic  Control Specialist assigned to radar monitor the  flight path of aircraft during simultaneous parallel  (approach courses spaced less than 9000 feet/9200  feet above 5000 feet) and simultaneous close parallel  approach operations. Each runway is assigned a final  monitor controller during simultaneous parallel and  simultaneous close parallel ILS approaches.  FIR- FIS-B- (See FLIGHT INFORMATION REGION.)  FIRST TIER CENTER- An ARTCC immediately  adjacent to the impacted center.  (See FLIGHT INFORMATION  SERVICE-BROADCAST.)  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  PCG F-2
