parking position intended for air transport operations:

 (i) for horizontal illuminance at a parking position with an aerodrome reference code letter — a minimum lux rating in accordance with Table 9.116 (3) for the code letter, with a uniformity ratio (average to minimum) of not more than 4:1; and

 (ii) for vertical illuminance at a parking position with an aerodrome reference code letter — a minimum lux rating in accordance with Table 9.116 (3) for the code letter, at a height of 2 m above the apron in the relevant parking direction, along the aeroplane centreline until the point where the rearmost passenger or cargo door of the intended aircraft is reached;

(b) at an aircraft parking position not intended for air transport operations — a minimum lux rating for horizontal illuminance in accordance with Table 9.116 (3) with a uniformity ratio (average to minimum) of not more than 4:1;

(c) at other apron areas — horizontal illuminance at 50% of the average minimum illuminance for the highest code for the associated parking positions on the apron, in accordance with Table 9.116 (3), with a uniformity ratio (average to minimum) of not more than 4:1.

       (4) For paragraph (3) (a), illuminance measurements at the time of commissioning and during any subsequent checks, including those made during the aerodrome technical inspection, must be taken as follows:

 1.       for horizontal illuminance — measured with a clear line of sight to the source of apron floodlighting;

        2.    for vertical illuminance:

           (i) measured perpendicular to the centreline of the parked aircraft, with the lux meter facing outwards from the centreline; and

 (ii) measured in opposing directions; and

 (iii) with a clear line of sight to the source of apron floodlighting.

       (5) For subsection (3), for a parking position with an aerodrome reference code letter mentioned in a row of column 1 of Table 9.116 (3), the minimum parking position average illuminance for an apron intended for air transport operations, and for an apron not intended for air transport operations, respectively, is the illuminance mentioned in the same row in column 2 and column 3, respectively.

       (6) Subsection (3) does not apply for the purposes of aircraft manoeuvring if taxiway lights provide continuous guidance between the taxiway and the parking position.

Note   The aerodrome operator may nominate a different code for each parking position. However the required illuminance for the other areas of the apron is dependent upon the highest code of parking position on the apron. This ensures the illuminance of markings associated with apron taxiways and taxilanes will be provided until the aircraft reaches the parking position.

The uniformity ratio between the average of all values of illuminance is measured over a grid
