II-2-5-2 Procedures — Aircraft Operations — Volume II
D is described by the following equation:
where: D = the radius in km [NM]
23/11/06
V = true aircraft speed in km/h [kt]
t = outbound time in minutes.
D=( V
60 +1.9)t+2.8km
[D = ( V
60 +1.0)t+1.5NM]
This sector shall be extended in all directions by a margin of 3.7 km (2.0 NM). (See Figure II-2-5-1.)
5.3.3 Obstacle clearance in the initial approach
The obstacle clearance in the initial approach area shall be 300 m (984 ft).
5.4 INTERMEDIATE SEGMENT
This type of procedure has no intermediate segment. Upon completion of the base turn, the aircraft is on final approach.
5.5 FINAL APPROACH SEGMENT
5.5.1 General
The final approach begins where the base turn intersects the final approach track inbound.
5.5.2 Alignment
5.5.2.1 The alignment of the final approach track with respect to:
a) the facility;
b) the runway centre line; and
c) the runway threshold,
will determine whether a straight-in or circling approach may be established. (See Part I, Section 4, Chapter 5, 5.2,
“Alignment”.)
