Factor of safety. A design factor used to provide for the possibility of loads greater than those assumed, and for uncertainties
in design and fabrication.

Final approach fix or point. That fix or point of an instrument approach procedure where the final approach segment
commences.

Fan marker beacon. A type of radio beacon, the emissions of which radiate in a vertical fan-shaped pattern

Farad (F). The capacitance of a capacitor between the plates of which there appears a difference of potential of 1 volt when
it is charged by a quantity of electricity equal to 1 coulomb.

Fatigue. A physiological state of reduced mental or physical performance capability resulting from sleep loss or extended
wakefulness, circadian phase, or workload (mental and/or physical activity) that can impair a crew member’s alertness and
ability to safely operate an aircraft or perform safety-related duties.

Final approach and take-off area (FATO). A defined area over which the final phase of the approach manoeuvre to hover or
landing is completed and from which the take-off manoeuvre is commenced. Where the FATO is to be used by
performance Class 1 helicopters, the defined area includes the rejected take-off area available.

FBL - Used in meteorology meaning "light" as in precipitation or icing.

‘Feathered Pitch’ means the pitch setting, specified in the appropriate propeller manual, which in flight with the engine stopped, gives approximately the minimum drag, and corresponds with a windmilling torque of approximately zero.

Forward error correction (FEC). The process of adding redundant information to the transmitted signal in a manner which
allows correction, at the receiver, of errors incurred in the transmission.

Final approach. 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.
