the distance between the threshold and the PAPI (D1, shown in Figure 9.50 (5)) must ensure that the lowest height at which a pilot will see a correct approach path indication will provide the wheel clearance over the threshold specified in Table 9.50 (4) for the most demanding of the aeroplanes regularly using the runway.

       (7) If a PAPI is installed on a runway that is equipped with an ILS, the distance between the threshold and the PAPI (D1, shown in Figure 9.50 (5)) must ensure the optimum compatibility between the visual and non-visual aids for the range of eye-to-antenna heights of the aeroplanes regularly using the runway.

       (8) If a wheel clearance greater than that specified in subsection 9.50 (4) is required for specific aircraft, this must be achieved by increasing the distance D1 shown in Figure 9.50 (5).

       (9) The distance D1 shown in Figure 9.50 (5) must be adjusted to compensate for differences in elevation between the lens centres of the light units and the threshold.

       (10) PAPI units must be no more than 0.9 m above ground level.

       (11) Subject to subsection (12), all units of a wing bar must, as far as possible, lie in the same horizontal plane.

       (12) However:

(a) small height differences of no more than 50 mm between light units are permitted if required to allow for any transverse slope; and

(b) a lateral gradient not greater than 1.25% is permitted if it is uniformly applied across the units.

CHAPTER 9

Division 10 Runway lights

9.51 Runway edge lights

       (1) Runway edge lights must be provided for the following:

(a) a non-instrument or non-precision runway intended for use at night;

(b) a precision approach runway intended for use by day or night.

Note   Low-intensity lighting systems will typically form a configuration under paragraph (1) (a), unless a medium-intensity system is required due to environmental factors unique to the aerodrome.

       (2) A runway intended for use at night for any of the following:

(a) visual circling;

(b) circuits;

(c) both visual circling and circuits;

        must have omnidirectional runway edge lights that comply with the requirements in section 9.52.

       (3) A runway available for take-off operations with an RVR less than 350 m must have runway edge lights that comply with the requirements in section 9.53.

       (4) Runway edge lights must be placed along both sides of a runway so that they:

(a) are in 2 parallel straight rows equidistant from the centreline with the pairs of lights opposite each other; and

(b) either:

 (i) for a non-instrument or non-precision approach runway:

             (A) commence from the threshold and continue
