be used in accordance with this MOS.

Note   Elevated lights are not recommended on pavements which aircraft or vehicles travel over, or in movement areas subject to significant jet blast.

       (2) Despite paragraph (1) (d), Configuration A runway guard lights may extend up to 500 mm above ground level.

Note   Configuration A runway guard lights are described in section 9.99.

       (3) If an inset light is not installed within a pavement, the inset light must be protected from vegetation growth for a minimum radius of 1 m around the light by being installed:

(a) on a sealed surface; or

(b) on a surface with a protective cover; or

(c) on a surface that is treated, and maintained, in accordance with procedures in the aerodrome manual.

       (4) Inset lights must:

(a) ensure that runway and taxiway sight distance requirements are met; and

        Note   See sections 6.07 and 6.42.

(b) not have any sharp edges; and

(c) where the lights will not normally come into contact with aircraft wheels — not project more than 25 mm above or below the surrounding surface at each light's location; and

          Note   For example, threshold lights, runway end lights and runway edge lights.

(d) not project more than 13 mm above the surrounding surface at any location which will normally come into contact with aircraft wheels.

       Note   For example, runway centreline lights, touchdown zone lights and taxiway centreline lights.

       (5) The design of an inset light fixture must be such that the surface temperature of the light does not exceed 160°C when it is:

(a) operating at its maximum intensity; and

(b) covered by the wheel of a ground vehicle or aircraft continuously for 10 minutes.

       (6) The design of an inset light fixture must be such that it will not distort or otherwise fail when subjected to the wheel loads of the intended aircraft over its expected operational life.

Note   Refer to FAA Advisory Circular 150/5345-46, as in force or existing from time to time, and freely available from the FAA website, www.faa.gov, for an acceptable means of compliance.

       (7) Maintenance must be conducted to ensure that surface contaminants on or around an elevated light or an inset light fitting do not obscure or cover the light beam.

9.12 Lighting intensity and control

       (1) Lighting intensity must be controlled so that, in conditions of minimum visibility, a pilot is not subjected to a light output that may have an adverse effect on aviation safety (a hazardous light output).

       (2) Data on the operating current and the corresponding intensity selection must be documented in the aerodrome manual.

       (3) At an aerodrome with an ATS provider, each of the following lighting systems, if provided, must be equipped
