Figure 9.111 (3)   Isocandela diagram for taxiway centreline lights, no entry bar lights and stop bar lights on taxiways intended for use in RVR conditions less than 350 m — for use on straight sections of taxiways where large offsets can occur; also for runway guard lights, Configuration B (shows matters)

Note   These beam coverages allow for displacement of the cockpit from the centreline of up to a distance of 12 m and are intended for use before and after curves.

Note 1   These beam coverages are suitable for a normal displacement of the cockpit from the centreline of up to 3 m.

Note 2   See section 9.111 concerning these isocandela diagrams.

Note   Lights on curves must have the light beam toed-in 15.75º with respect to the tangent to the curve.

CHAPTER 9

Division 12 Apron lights

9.113 Apron floodlighting

        This Division sets standards for apron floodlighting where it is provided.
Note   ICAO establishes only one apron floodlighting standard. Australia, however, has a 3-tier system:
(a) high illuminance standards for aprons intended to serve larger aeroplanes engaged in air transport operations; and
(b) a mid-range illuminance standard for aprons intended to serve smaller aeroplanes engaged in air transport operations or large aircraft not engaged in air transport operations; and
(c) a lower standard for aprons without air transport operations.

9.114 Provision of apron floodlighting

       (1) Apron floodlighting must be provided on any of the following intended for use at night:

(a) an apron;

(b) a part of an apron;

(c) an aircraft parking position;

(d) a
