9.2.2.6.2 Recommendation
Location and characteristics
9.2.2.6.3 A touchdown zone marking shall consist of pairs of rectangular markings symmetrically disposed about the runway centre line with the number of such pairs related to the landing distance available and, where the marking is to be displayed at both the approach directions of a runway, the distance between the thresholds, as follows:
| Landing distance available or the distance between thresholds | Pair(s) of markings |
| Less than 900 m | 1 |
| 900m up to but not including 1 200 m | 2 |
| 1 200m up to but not including 1 500 m | 3 |
| 1 500m up to but not including 2 400 m | 4 |
| 2 400m or more | 6 |
9.2.2.6.4 A touchdown zone marking shall conform to either of the two patterns shown in ICAO Annex 14 Vol. I, Figure 5-5. For the pattern shown in ICAO Annex 14 Vol. I, Figure 5-5 (A), the markings shall be not less than 22.5 m long and 3 m wide. For the pattern shown in ICAO Annex 14 Vol. I, Figure 5-5 (B), each stripe of each marking shall be not less than 22.5 m long and 1.8 m wide with a spacing of 1.5 m between adjacent stripes. The lateral spacing between the inner sides of the rectangles shall be equal to that of the aiming point marking where provided. Where an aiming point marking is not provided, the lateral spacing between the inner sides of the rectangles shall correspond to the lateral spacing specified for the aiming point marking in Table 9-1 of this Manual (columns 2, 3, 4 or 5, as appropriate). The pairs of markings shall be provided at longitudinal spacings of 150 m beginning from the threshold except that pairs of touchdown zone markings coincident with or located within 50 m of an aiming point marking shall be deleted from the pattern.
