Figure 10 - 5 Runway Aiming Point Marking, in m
Runway Touchdown Zone Marking.- Purpose.
For landing operations, the touchdown zone marking identifies the touchdown zone along a
precision runway in 152-m increments As shown in Figure10- 7.
- Location.
 The touchdown zone marking consists of symmetrically arranged pairs of rectangular bars in groups
 of one, two, and three along the runway centerline as shown in Figure 10- 5. When both runway
 ends require runway touchdown zone markings. The beginning of the touchdown zone marking
 starts 500 feet ( 152 m) from the runway threshold, as shown in Figure 10-6. A full set of markings
 is needed when applying Table 10- 6 criteria, which take into account the “no-marking zones” of
 550 m from the runway midpoint in one direction.
- Color.
All rectangular bars are white.
