INTERMEDIATE APPROACH SEGMENT
4.1 GENERAL
4.1.1 The intermediate approach segment blends the initial approach segment into the final approach segment. It
is the segment in which aircraft configuration, speed, and positioning adjustments are made for entry into the final
approach segment.
4.1.2 There are two types of intermediate approach segments:
a) one which begins at a designated intermediate approach fix (IF); and
b) one which begins upon completion of a dead reckoning (DR) track, a reversal or a racetrack procedure.
4.1.3 In both cases, track guidance shall be provided inbound to the final approach fix (FAF) where the
intermediate approach segment ends. See Figure I-4-3-2 of Chapter 3 for typical intermediate approach segments.
4.2 ALTITUDE/HEIGHT SELECTION
The minimum altitude/height in the intermediate approach segment shall be established in 100-ft increments or 50-m
increments as appropriate.
4.3 INTERMEDIATE APPROACH SEGMENT BASED ON A
STRAIGHT TRACK ALIGNMENT
The track to be flown in the intermediate approach segment should normally be the same as the final approach track.
Where this is not practicable and the final approach fix in a non-precision procedure is a navigation facility, the
intermediate track shall not differ from the final approach track by more than 30° (Cat H, 60°). Where the turn at the
FAF is greater than 10° the final approach area should be widened on the outer side of the turn as described in
Chapter 6, 6.4.6.3.3, “TP marked by a facility (NDB or VOR)”.
4.3.1 Area
This section deals with the construction of the area of an intermediate approach segment based on a straight track
alignment.
