with the serviceable taxiway centreline lights for 2 light spacings within each end of the unserviceable area (to ensure a graduated transition).

9.09 Light fixtures and supporting structures

       (1) All aerodrome light fixtures and, subject to subsection (2), supporting structures must be:

(a) independently certified (that is by a person independent from the manufacturer) for frangibility in accordance with the standards on frangibility under:

 (i) ICAO Document 9157, Aerodrome Design Manual Part 4 – Visual Aids, Chapter 15, Frangibility of Visual Aids; and

 (ii) ICAO Document 9157, Aerodrome Design Manual Part 6 – Frangibility; and

(b) of the minimum weight that is consistent with the fixture or structure being fit for its function.

Note   For ICAO documents, see section 1.07.

       (2) In the portion of the approach lighting system that is more than 300 m from the runway threshold:

(a) if the height of the structure exceeds 12 m — the frangibility requirement mentioned in subsection (1) applies only to the top 12 m of the supporting structure; and

(b) if the supporting structure is surrounded by non-frangible objects — only that part of the structure that extends above the surrounding objects must be frangible.

       (3) If an approach lighting fixture, or its supporting structure, is not in itself clearly conspicuous to the pilot of an approaching aircraft, it must be marked in accordance with Chapter 8, Division 10.

9.10 Standardisation of aerodrome lighting

       (1) Lights with different design types must not be mixed in a lighting system unless their photometric characteristics:

(a) are matched as closely as possible; and

(b) are not visually distracting or confusing to pilots; and

(c) otherwise meet the requirements of this MOS.

       (2) Solid state lights and incandescent lights must not be mixed:

(a) within any individual lighting system on a runway, including the following:

 (i) threshold lighting;

 (ii) edge lighting;

 (iii) centreline lighting;

 (iv) end lighting;

 (v) approach lighting;

 (vi) touchdown zone lighting;

 (vii) visual approach slope indicator system lighting; or

(b) in the lighting within a taxiway section.

9.11 Elevated and inset lights

       (1) Elevated lights must:

(a) be frangible; and

(b) have yellow casings; and

        Note   See subsection 8.03 (2) for the standard colour for "yellow".

(c) on taxiways — be sited clear of aircraft propellers and jet engine pods for the aircraft code letter for which the taxiway is designed; and

(d) not extend more than 360 mm above ground level; and

(e) not be used when inset lights must 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.
