Note   The provision of aiming point markings may require 1 pair of touchdown zone markings to be omitted. As a result, for the Table, the numbers of pairs of touchdown zone markings do not necessarily align with the numbers of locations.

8.25 Touchdown zone markings — simple touchdown pattern

       (1) As shown in Figure 8.25 (1), a simple touchdown zone marking must comprise 4 white stripes, each not less than 22.5 m long and 3 m wide, located in pairs such that the ends of each pair of stripes nearest the threshold are 150 m and 450 m, respectively, from the line of the runway threshold. The lateral spacing between the inner sides of each pair of markings must be equal to that of the aiming point marking.
       (2) If simple runway touchdown zone markings are provided on a runway that is less than 1 500 m in length, the markings at 450 m from the end of the runway threshold may be omitted.

8.26 Permanently displaced threshold markings

       (1) If a runway threshold is permanently displaced, permanently displaced threshold markings must be provided as shown in Figures 8.26 (1)-1 and 8.26 (1)-2.

       (2) The markings must take the form of a sequence of 30 m long white arrows as follows:

(a) the first arrow must point in the direction of the displaced threshold;

(b) the tip of the head of the first arrow must end 20 m from the commencement of the displaced threshold's white "piano key" markings;

(c) preceding complete arrows, pointing in the direction of the displaced threshold, must be provided at 20 m intervals until the reciprocal runway end is reached;

Note   A partial arrow must not be used if there is insufficient space at the reciprocal runway end for a complete arrow.

(d) the head of each arrow must:

 (i) be 10 m long with a line thickness of between 0.9 m and 1 m; and

 (ii) have arms that are 3.5 m apart at their widest dimension; and

 (iii) commence from the end of the stem with the tip of the arrowhead pointing towards the displaced runway threshold; and

(e) the stem of each arrow must be 30 m long and the same width as the centreline marking;

(f) the combined length of the arrowhead, the arrow stem and the gap between
