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

       (1) If a runway or a system of runways is intended to be used in RVR conditions less than 350 m, a stop bar must be provided at each runway holding position serving the runway or the system of runways.

       (2) Subsection (1) does not apply if operational procedures ensure that, in RVR conditions less than 350 m, the number of:

(a) aircraft on the manoeuvring area is limited to 1 at a time; and

(b) vehicles on the manoeuvring area is limited to the minimum essential for safe aerodrome operations.

       (3) If a runway is intended to be used in RVR conditions of at least 350 m but less than 550 m, a stop bar must be provided at each runway holding position serving the runway.

       (4) Subsection (3) does not apply if:

(a) operational procedures ensure that in RVR conditions of at least 350 m but less than 550 m, the number of:

 (i) aircraft on the manoeuvring area is limited to 1 at a time; and
 (ii) vehicles on the manoeuvring area is limited to the minimum essential for safe aerodrome operations; or
(b) appropriate aids and procedures designed to prevent the inadvertent incursion of aircraft or vehicles onto the runway are in force for the runway.

Note 1   Stop bars require direct ATC control. Therefore, CASA recommends that an aerodrome operator should consult with ATC before planning their introduction. If provided, the control mechanism for stop bars should meet the operational requirements of the ATS provider at that aerodrome.

Note 2   CASA recommends that stop bars be used in RVR conditions of 550 m or more, or generally, to prevent runway incursions.

9.106 Location of stop bars

        A stop bar must:

(a) be located across the taxiway on, or not more than 0.3 m before, the point at which it is intended that traffic approaching the runway must stop; and

(b) consist of inset lights spaced 3 m apart across the taxiway; and

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

(d) be supplemented with a pair of elevated lights that:

 (i) have the same characteristics as the stop bar lights; and

 (ii) are provided abeam the stop bar; and

 (iii) are located at a distance of at least 3 m from the taxiway edge.

9.107 Characteristics of stop bar lights

       (1) A stop bar must:

(a) be unidirectional; and

(b) show red in the direction of approach to the stop bar.

       (2) The intensity and beam spread of the stop
