If:

(a) the permanent runway threshold is to be displaced for more than 5 days but not more than 30 days; and

(b) the runway is serving scheduled international air transport operations;

        then the temporarily displaced threshold markings must be accompanied by RTIL in accordance with subsection 8.27 (3).

8.30 Temporarily displaced threshold markings — 5 days or less

       (1) If a runway threshold is to be temporarily displaced for 5 days or less, the permanent threshold markings may be retained but the new threshold location must be indicated as follows:

(a) for runways serving scheduled international air transport operations — with RTIL only, in accordance with subsection 8.27 (3);

(b) for all other runways:

 (i) subject to subsection (2), with markers (Vee-bar markers) comprising gable markers coloured white and positioned on each side of the runway perpendicular to the centreline, together with flush, white arrow markings in the direction of landing, as shown in Figure 8.29 (1); or

 (ii) with RTIL only, in accordance with subsection 8.27 (3);

       (2) For subparagraph (1) (b) (i):

(a) for runways that are more than 18 m wide, or runways serving air transport operations — there must be 2 Vee-bar markers on each side of the runway; and

(b) for runways that are 18 m wide and not serving air transport operations — there must be at least 1 Vee-bar marker on each side of the runway.

8.31 Temporarily displaced threshold markings — large displacements for 30 days or less

       (1) Despite sections 8.29 and 8.30, if:

(a) a runway threshold is temporarily displaced for not more than 30 days; and

(b) the displacement is by more than 450 m; and

(c) RTIL are not provided;

        then temporarily displaced threshold markings must be provided in accordance with section 8.28.

       (2) If:

(a) a threshold is temporarily displaced for not more than 5 days; and

(b) the displacement is by more than 450 m; and

(c) 24 hour ATC services are provided;

then the permanent threshold markings may be retained if RTIL are provided.

Note   Markings of some typical threshold and displaced threshold scenarios in Figures 8.31 (2)-1 to 8.31 (2)‑5 are illustrations only.
