Pilot/Controller Glossary

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-
(See FLIGHT INFORMATION REGION.)

FIRST PERSON VIEW- UAS operation in which imagery is transmitted to the UAS pilot by an onboard UA
camera.
FIRST TIER CENTER- An 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.
FLAMEOUT PATTERN- An approach normally conducted by a single-engine military aircraft experiencing
loss or anticipating loss of engine power or control. The standard overhead approach starts at a relatively high
altitude over a runway ("high key") followed by a continuous 180 degree turn to a high, wide position ("low key")
followed by a continuous 180 degree turn final. The standard straight-in pattern starts at a point that results in
a straight-in approach with a high rate of descent to the runway. Flameout approaches terminate in the type
approach requested by the pilot (normally fullstop).
FLIGHT CHECK- A call sign prefix used by FAA aircraft engaged in flight inspection/certification of
navigational aids and flight procedures. The word "recorded" may be added as a suffix; e.g., "Flight Check 320
recorded" to indicate that an automated flight inspection is in progress in terminal areas.
(See FLIGHT INSPECTION.)
(Refer to AIM.)

FLIGHT DATA [FSS]" The primary task of the FSS flight data position is information management. Flight data
services include the development, translation, processing, and coordination of aeronautical, meteorological, and
aviation information.
FLIGHT FOLLOWING-
(See TRAFFIC ADVISORIES.)

FLIGHT INFORMATION REGION- An airspace of defined dimensions within which Flight Information
Service and Alerting Service are provided.
a. Flight Information Service. A service provided for the purpose of giving advice and information useful for
the safe and efficient conduct of flights.
b. Alerting Service. A service provided to notify appropriate organizations regarding aircraft in need of search
and rescue aid and to assist such organizations as required.
FLIGHT INFORMATION SERVICE- A service provided for the purpose of giving advice and information
useful for the safe and efficient conduct of flights.
