8.28 Temporarily displaced threshold markings — more than 30 days

        If a permanent runway threshold is to be displaced for more than 30 days, the temporarily displaced threshold markings must comply with the following:

(a) a white line, that is 1.2 m wide, must be marked across the full width of the runway at the line of the new threshold, together with adjacent 10 m long white arrowheads, whose lines are 1 m wide;

(b) existing centreline markings between the reciprocal runway end and the displaced threshold must be converted into arrows as shown in Figure 8.28;

(c) the permanent threshold marking and associated runway designation number must be obscured, and a temporary runway designation number provided 12 m beyond the new threshold.

Note 1   The existing centreline markings between the displaced threshold and the runway end do not need to be altered unless the temporary displacement is made permanent, in which case the requirements of section 8.26 would apply.

Note 2   If the runway aiming point marking or the touchdown zone marking may cause confusion with the new threshold location, CASA recommends that those markings also be obscured.

8.29 Temporarily displaced threshold markings — more than 5 days to 30 days or less

       (1) 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 not serving scheduled international air transport operations; and

(c) RTIL are not provided in accordance with subsection 8.27 (3);

        then the temporarily displaced threshold markings must consist of the following:

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

(e) for runways more than 18 m wide, or those serving air transport operations — 2 gable markers abutted end-to-end and positioned perpendicular to the centreline, and 2 arrow markings in the landing direction, must be provided on each side of the runway;

(f) for runways that are 18 m wide and not serving air transport operations — a minimum of 1 gable marker positioned perpendicular to the centreline, and 1 arrow marking in the landing direction, must be provided on each side of the runway.

       (2) The existing threshold markings must be obscured.

      (3) 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
