be unidirectional and aligned so as to be visible to the pilot of an aeroplane taxiing to the holding position;

(d) the effective intensity of the yellow beam and beam spread must be the same as that in the specifications in Figure 9.111 (3).

9.101 Control of runway guard lights

        All runway guard lights for a runway must be capable of being turned on when the runway is active, whether by day or night.

9.102 Provision of intermediate holding position lights

        Intermediate holding position lights must be provided at the following locations:

(a) if runway guard lights or stop bars are not provided — the runway holding position on a taxiway serving a runway equipped for night use;

(b) if the holding bay is intended to be used at night— the holding position of a holding bay;

(c) taxiway/taxiway intersections if:

 (i) the intersection is intended for use in RVR conditions less than 350 m; and

 (ii) it is necessary to identify the aircraft holding position;

(d) a designated intermediate holding position on a taxiway intended for night use.

Note   Provision of intermediate holding position lights for subparagraph (c) (ii) and paragraph (d) is based on local ATC procedural requirements.

9.103 Pattern and location of intermediate holding position lights

       (1) On a taxiway equipped with centreline lights, the intermediate holding position lights must consist of at least 3 lights that are:

(a) inset, and spaced 1.5 m apart; and

(b) disposed symmetrically about, and at right angles to, the taxiway centreline; and

(c) located not more than 0.3 m before whichever of the following is appropriate, depending on the required location of the intermediate holding position lights:

 (i) the intermediate holding position marking;

 (ii) the taxiway intersection marking.

       (2) On a taxiway equipped with taxiway edge lights, the intermediate holding position lights must:

(a) consist of 1 elevated light on each side of the taxiway; and

(b) be located in line with:

 (i) the taxiway edge lights; and
 (ii) one of the following:
             (A) the runway holding position marking;
             (B) the intermediate holding position marking;
             (C) the taxiway intersection marking.

9.104 Characteristics of intermediate holding position lights

       (1) Inset intermediate holding position lights must:

(a) be fixed, unidirectional lights showing yellow; and

(b) be aligned so as to be visible to the pilot of an aircraft approaching the holding position; and

(c) have light distribution as close as possible to that of the taxiway centreline lights.

       (2) Elevated intermediate holding position lights must:

(a) be fixed, omnidirectional lights showing yellow; and

(b) have light distribution as close as possible to that of the taxiway edge lights.

9.105 Stop bars
