FLIGHT PLAN AREA (FPA)

 The geographical 

area assigned to a flight service station (FSS) for the 
purpose of establishing primary responsibility for 
services that may include search and rescue for VFR 
aircraft, issuance of NOTAMs, pilot briefings, 
inflight services, broadcast services, emergency 
services, flight data processing, international opera-
tions, and aviation weather services.  Large 
consolidated FSS facilities may combine FPAs into 
larger areas of responsibility (AOR).

FLIGHT RECORDER

 A general term applied to 

any instrument or device that records information 
about the performance of an aircraft in flight or about 
conditions encountered in flight. Flight recorders 
may make records of airspeed, outside air 
temperature, vertical acceleration, engine RPM, 
manifold pressure, and other pertinent variables for a 
given flight. 

(See ICAO term FLIGHT RECORDER.) 

FLIGHT RECORDER [ICAO]

 Any type of 

recorder installed in the aircraft for the purpose of 
complementing accident/incident investigation. 

Note: See Annex 6 Part I, for specifications relating 

to flight recorders. 

FLIGHT SERVICE STATION (FSS)

 An air traffic 

facility which provides pilot briefings, flight plan 
processing, en route flight advisories, search and 
rescue services, and assistance to lost aircraft and 
aircraft in emergency situations. FSS also relay ATC 
clearances, process Notices to Air Missions, and 
broadcast aviation weather and aeronautical 
information. In Alaska, FSS provide Airport 
Advisory Services. 

(See FLIGHT PLAN AREA.) 
(See TIE-IN FACILITY.) 

FLIGHT STANDARDS DISTRICT OFFICE

 An 

FAA field office serving an assigned geographical 
area and staffed with Flight Standards personnel who 
serve the aviation industry and the general public on 
matters relating to the certification and operation of 
air carrier and general aviation aircraft. Activities 

include general surveillance of operational safety, 
certification of airmen and aircraft, accident 
prevention, investigation, enforcement, etc. 

FLIGHT TERMINATION

  The intentional and 

deliberate process of terminating the flight of a UA in 
the event of an unrecoverable lost link, loss of 
control, or other failure that compromises the safety 
of flight. 

FLIGHT TEST

 A flight for the purpose of: 

a. 

Investigating the operation/flight characteris-

tics of an aircraft or aircraft component. 

b. 

Evaluating an applicant for a pilot certificate or 

rating. 

FLIGHT VISIBILITY

 

(See VISIBILITY.) 

FLIP

 

(See DOD FLIP.) 

FLY-BY WAYPOINT

 A fly-by waypoint requires 

the use of turn anticipation to avoid overshoot of the 
next flight segment. 

FLY HEADING (DEGREES)

 Informs the pilot of 

the heading he/she should fly. The pilot may have to 
turn to, or continue on, a specific compass direction 
in order to comply with the instructions. The pilot is 
expected to turn in the shorter direction to the heading 
unless otherwise instructed by ATC. 

FLY-OVER WAYPOINT

 A fly-over waypoint 

precludes any turn until the waypoint is overflown 
and is followed by an intercept maneuver of the next 
flight segment. 

FLY VISUAL TO AIRPORT

 

(See PUBLISHED INSTRUMENT APPROACH 

PROCEDURE VISUAL SEGMENT.) 

FLYAWAY

 When the pilot is unable to effect control 

of the aircraft and, as a result, the UA is not operating 
in a predictable or planned manner. 

FMA

 

(See FINAL MONITOR AID.) 

FMS

 

(See FLIGHT MANAGEMENT SYSTEM.) 

FORMATION FLIGHT

 More than one aircraft 

which, by prior arrangement between the pilots, 
operate as a single aircraft with regard to navigation 
and position reporting. Separation between aircraft 
within the formation is the responsibility of the flight 
leader and the pilots of the other aircraft in the flight.
