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

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.
