PCG F−2

lower-than-published glideslope/path intercept alti-

tude, it is the resultant actual point of the

glideslope/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 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.
FIR−

(See FLIGHT INFORMATION REGION.)

FIRST TIER CENTER− The ARTCC immediately

adjacent to the impacted center.
FIS−B−

(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

b.

Signal strength or quality of the received signal

falls below acceptable values.
FLAG ALARM−

(See FLAG.)

FLAMEOUT− An emergency condition caused by a

loss of engine power.
