FERRY FLIGHT- A flight for the purpose of:
a..Returning an aircraft to base.
b.
Delivering an aircraft from one location to another.

c..
Moving an aircraft to and from a maintenance base.- Ferry flights, under certain conditions, may be conducted under terms of a special flight permit.

FIELD ELEVATION-
(See AIRPORT ELEVATION.)
FILED- Normally used in conjunction with flight plans, meaning a flight plan has been submitted to ATC.
FILED EN ROUTE DELAY- Any of the following preplanned delays at points/areas along the route of flight which require special flight plan filing and handling techniques.
a..
Terminal Area Delay. A delay within a terminal area for touch‐and‐go, low approach, or other terminal area activity.

b..
Special Use Airspace Delay. A delay within a Military Operations Area, Restricted Area, Warning Area, or ATC Assigned Airspace.

c.
Aerial Refueling Delay. A delay within an Aerial Refueling Track or Anchor.

FILED FLIGHT PLAN- The flight plan as filed with an ATS unit by the pilot or his/her designated representative without any subsequent changes or clearances.
FINAL-Commonly used to mean that an aircraft is on the final approach course or is aligned with a landing area.
(See FINAL APPROACH COURSE.)
(See FINAL APPROACH‐IFR.)
(See SEGMENTS OF AN INSTRUMENT
APPROACH PROCEDURE.)
FINAL APPROACH [ICAO]- That part of an instrument approach procedure which commences at the specified final approach fix or point, or where such a fix or point is not specified.
a..
At the end of the last procedure turn, base turn or inbound turn of a racetrack procedure, if specified; or

b..
At the point of interception of the last track specified in the approach procedure; and ends at a point in the vicinity of an aerodrome from which:

1..
A landing can be made; or

2..
A missed approach procedure is initiated.

FINAL APPROACH COURSE- A bearing/radial/ track of an instrument approach leading to a runway or an extended runway centerline all without regard to distance.
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 for precision approaches; or when ATC directs a 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.
