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 bar lights must be in accordance with the applicable specifications in Figures 9.111 (1) to 9.111 (5).

       (3) Selectively-switchable stop bars must be installed in conjunction with at least 3 taxiway centreline lights that extend for a distance of at least 90 m from the stop bar in the direction that it is intended for an aircraft to proceed from the stop bar.

       (4) The lighting circuit of a stop bar must be designed so that:

(a) stop bars located across the entrances to taxiways are selectively switchable; and

(b) stop bars located across taxiways used as exit taxiways only are switchable selectively or in groups; and

(c) when a stop bar is illuminated, any taxiway centreline lights immediately beyond the stop bar are extinguished for a distance of at least 90 m; and

(d) when a stop bar is extinguished, any taxiway centreline lights immediately beyond the stop bar are illuminated for a distance of at least 90 m; and

(e) with control interlock (not manual control):

 (i) if the taxiway centreline lights beyond the stop bar are illuminated — the stop bar is extinguished; and

 (ii) if the stop bar lights are illuminated — the taxiway centreline lights beyond the stop bar are extinguished.

9.108 No entry bars

       (1) No entry bars must be provided at the entry of a permanently closed taxiway at an aerodrome available for use at night where aircraft no entry signs as specified in section 8.90 are not provided.

       (2) No entry bars may be provided at the entry of a permanently closed taxiway or an exit-only taxiway.

Note 1   Runway incursions may take place in all visibility or weather conditions. The provision of no entry bars at taxiway/runway intersections and their use at night and in all visibility conditions can form part of effective runway incursion prevention measures.

Note 2   It is recommended that a no entry bar should be provided across a taxiway which is intended to be used as an exit-only taxiway to assist in preventing inadvertent access of traffic to that taxiway.

       (3) If provided, a no entry 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 closed or exit-only taxiway 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.
