Details of lighting available at New Zealand aerodromes are presented on the aerodrome charts in the AIPNZ, Vol 2, 3 and 4. Information on aerodrome lighting at New Zealand international aerodromes is also presented in the AIPNZ in Vol 1, AD 2. Details of lighting at South Pacific island aerodromes within the Auckland and Nadi Oceanic FIRs (excluding Pago Pago, Port Vila and New Caledonia sectors) are presented in the Pacific AIP.
In weather conditions likely to cause condensation or water on the lenses of visual aids, pilots are advised to operate PAL or VHF remote control of lighting as soon as practicable so that the aid can have a 5 minute warm-up. This will reduce the likelihood of false indications through optical distortion.
Permanently installed runway lighting will be classified according to the available light intensity as either light intensity high (LIH), light intensity medium (LIM) or light intensity low (LIL). This intensity classification appears in the lighting box on the landing chart in AIPNZ.
On precision approach runways, high intensity lighting is normally provided with five stages of intensity control. Other runways are normally provided with two stage intensity lighting.
The initial intensity setting is selected by ATS to suit prevailing visibility requirements. Pilots may request alteration of the intensity setting to suit individual requirements.
Aircraft may taxi on the movement area at an aerodrome reporting an RVR of 550m or more provided that:
Aircraft may taxi on the movement area at an aerodrome reporting an RVR of 550m; or the RVR of the associated departure procedure; whichever is the less, provided that:
Permanently installed runway lighting consists of runway edge lights, threshold lights, and runway end lights.
Is normally white for the usable portion of the runway.
May extend across the full width of the runway or have a clear gap about the central section. This lighting is normally uni-directional green, visible from the approach direction.
Is installed across the end of the runway. It may extend across the full width of the runway or have a clear gap about the central section. This lighting is normally uni-directional red, visible from the direction of the runway.
Where a landing threshold is displaced, the runway end lights may not be coincident with the threshold lighting. When this occurs the runway edge lighting, between the landing threshold and the runway end lights, will be uni-directional red visible from the approach direction and uni-directional white visible from the runway. On non-precision approach runways the displaced threshold lighting may be provided by a wing bar display of lights outboard of the runway edges. This landing threshold lighting is normally uni-directional green, visible from the approach direction.
A precision approach runway may also be provided with flush centre line lights over the whole length of the runway. This lighting will be coded to show white from the threshold to a point 914m from the runway end; alternate red and white between 914m and 300m from the runway end; and red between 300m and the runway end.
Comprises a very high intensity uni-directional light projector located on either side of the runway approximately 30m from the runway extended centre line and downwind of the landing threshold. The projectors are aligned to be visible from the approach direction, and are synchronised to flash simultaneously and to show brilliant white flashes at a rate of 60 flashes per minute. The projectors have two intensities.
Four different types of approach light systems are in use in New Zealand:
Circling Guidance Lighting (CGL) is installed to provide either: positive tracking in terrain or obstacle restricted circuit areas, or
To provide a clear indication of landing threshold, a system of high intensity white lights is used to identify and locate the landing threshold during the later part of the downwind leg and on base leg. These allow a pilot to determine the point at which to turn from the downwind leg onto base leg, and from base leg onto final approach. Two lights are located outboard of the threshold and a further light is positioned at the outer extremity of each crossbar of the approach light system. The lights at the threshold and on the two innermost crossbars are aligned in azimuth in the circuit direction and at 90º to the runway centre line. The lights on the third, fourth and fifth crossbars are aligned in azimuth at 80º, 60º, and 30º respectively from the runway centre line. All lights are elevated 6º above the horizontal so as to be visible in the appropriate areas of the circuit. The system does not provide a fixing service but is intended to indicate the threshold position from the circuiting area only, in conditions of reduced visibility by day and by night.
Where approach slope indicators are installed, the azimuth coverage of the circling guidance lighting is restricted so as not to be visible in the area of approach slope indicator coverage.
Runway Lead in Lighting (RLLS) may be provided where additional lighting is required to provide positive tracking to an aerodrome or to the commencement of the approach lighting. RLLS is normally fixed or flashing omni-directional red lights. The outermost light may be a fixed or flashing amber and, where additional conspicuity is required, flashing omni-directional white lights may be provided.
Aerodromes in New Zealand may be equipped with a pilot activated VHF switching system to operate runway and associated lighting. Details are contained in the appropriate aerodrome charts in the AIPNZ Vol 2, 3 and 4.
At most aerodromes lighting duration is 20 minutes and a standard system of keying of the aircraft transmitter on the designated frequency achieves various lighting changes as follows:
Instructions for operation of the non-standard systems at other aerodromes are detailed on the aerodrome charts in the AIPNZ Vol 2, 3 and 4.
Remote control of lighting at aerodromes within New Zealand may be available by prior arrangement with the aerodrome operator or Chief Controller.
Remote control of lighting may also be available from the Area Flight Information Centre via a nominated VHF frequency. Pilots requesting activation via this method should call at least five minutes prior to departure or arrival specifying runway to be used. Adjustment of brilliance levels may take up to 1 minute to action. Pilots are required to advise when lighting is no longer required; this may be part of an arrival report.
