and any visual aids leading a pilot into the closed facility, must be extinguished or obscured except the lighting for visual aids used to warn pilots of the closed facility.

       (2) Subject to subsection (1), the restricted operation of visual aids is permissible for maintenance or related purposes.

       (3) For a partial or complete closure of a manoeuvring area for less than 5 days, the aerodrome lights for the closed area must be:

(a) obscured with an opaque cover that is as follows:

 (i) firmly attached to the ground so that it cannot be unintentionally dislodged;

 (ii) lightweight and frangible, and not otherwise posing a hazard to aircraft; or

(b) if not so obscured — electrically isolated or disabled to prevent their inadvertent activation.

       (4) For a partial or complete closure of a manoeuvring area for 5 days or more the aerodrome lights for the closed area must be electrically isolated or disabled to prevent their inadvertent activation.

9.128 Lighted visual aid to indicate a temporary complete runway closure

       (1) For a temporary unserviceability of the normal runway length, a lighted visual aid may be used at controlled aerodromes as follows:

(a) to supplement the extinguishing or obscuring of runway lighting;

(b) in-lieu of day time markings for runway closures of less than 24 hours duration;

(c) in conjunction with unserviceability markings as described in section 8.106.

Note   The aid must be in the form of a lit cross — see section 9.129.

       (2) The lighted visual aid must not be used:

(a) for partial closures or partial unserviceability of the normal runway length; or

        Note   Lighted visual aids are intended to be used for unserviceability.

(b) in conjunction with temporarily displaced threshold markings or lights; or

(c) at non-controlled aerodromes; or

(d) at controlled aerodromes during such times as Air Traffic Control services are not available.

       (3) The lighted visual aid must be:

(a) positioned within the permanent threshold of the runway at each end; and

(b) as far as possible — aligned with the runway centreline.

       (4) Additional lighted visual aids to indicate the temporary runway unserviceability may be located and spaced as required for runway unserviceability markings.

Note   For runway unserviceability markings, see, relevantly, subsections 8.106 (2) and (3).

9.129 Characteristics of a lighted visual aid to indicate a temporary complete runway closure

       (1) For section 9.128, the lighted visual aid must consist of an X-shaped cross with 2 lit arms.

       (2) For subsection (1), the arms of the X-shaped cross must:

(a) each be at least 6 m in length; and

(b) intersect at their midpoint (the intersection point):

 (i) at a preferred internal angle of 90 degrees; or

 (ii) so that a distinct X shape
