b) straight departure with track guidance:
23/11/06
1) facility ahead or behind; and
2) offset (track parallel/track offset/track crossing).
3.2.3 Track adjustment
In the construction of areas it is assumed that any track adjustments will take place no further along the track than a
point at which the PDG reaches 120 m (394 ft) (Cat H, 90 m (295 ft)) above the elevation of the DER, or at a specified
track adjustment point.
3.2.4.1 Departure with no track adjustment
3.2.4 Straight departure without track guidance
The area begins at the DER and has an initial width of 300 m (Cat H, 90 m). It is centred on the runway centre line and
splays at an angle of 15° on each side of the extended runway center line (see Figure I-3-3-1). The area terminates at
the end of the departure procedure as specified in Chapter 2, 2.4, “End of the departure procedure.”
3.2.4.2 Departure with track adjustment
3.2.4.2.1 The initial departure track may be adjusted by 15° or less. When adjusted, the splay of the area boundary
on the side of the track adjustment is increased by the track adjustment angle, starting at the DER.
3.2.4.2.2 On the side opposite the track adjustment, the boundary is adjusted by the same amount at a point where
the PDG reaches 120 m (394 ft) (Cat H, 90 m (295 ft)). This distance is nominally 3.5 km/1.9 NM (Cat H, 1.7 km/0.9
NM) from the DER for a 3.3 per cent PDG (Cat H, 5.0 per cent) (see Figure I-3-3-2).
3.2.4.2.3 Track adjustment point specified. If a track adjustment point is specified (see Figure I-3-3-3):
a) the splay of the area boundary on the side of the track adjustment is increased by the track adjustment angle,
from the earliest tolerance of the track adjustment point; and
b) the splay of the area boundary on the side opposite the track adjustment is reduced by the track adjustment
angle from the latest tolerance of the track adjustment point.
3.2.5.1 General
3.2.5 Straight departure with track guidance
The area is constructed as described in 3.2.4, “Straight departure without track guidance” and extended to the
point where the boundaries intercept the area associated with the navigation aid providing the track guidance (see
Figures I-3-3-4 to I-3-3-8).
