The continuously changing position of an aircraft in space directed toward effecting a landing on a predetermined area.

An approach which is not completed by landing.

That part of an instrument approach procedure in which alignment and descent for landing are accomplished. a. In a non-precision approach it normally begins at the final approach fix or point and ends at the missed approach point or fix. b. In a precision approach the final approach is deemed to commence at the glide path intercept point and ends at the decision height/altitude.

In approach and landing systems, a final approach in which the nominal flight path is not a straight line.

Equipment making use of radio to determine the position of an aircraft with considerable accuracy from the time it is in the vicinity of an aerodrome or carrier until it reaches a position from which landing can be carried out.
