Specification

ZA484 - runway centerline and TDZ inset high intensity light shall comply with ICAO Annex 14 figs 2.5, 2.6 and 2.7 and FAA L-850A and B for use in category I,II and III all weather operations.

Fixture shall be of modular design with the main casting manufactured in aluminum alloy, suitably protected against corrosion and finished in golden yellow or anodized aluminum.

The optical system shall comprise of maximum 3 lamps (2 lamps for threshold, 1 lamp for runway end) rated at 105W 6.6A max. Glass prisms shall be accurately located in the main casting, without the need for additional adhesives or sealants, to direct the light beams such that no re-focusing is required on installation, maintenance or in service. Dichroic coatings shall provide green or red light.

Lamp replacement shall be easily effected from the bottom of the fixture. The objective lamp life at maximum intensity shall not be less than 1,500 hours on a constant current series circuit at full intensity. The light fixture shall have an upper surface forming a smooth sloped face projecting not more than .5" (12.7mm) above the pavement surface. The fixture shall resist all stresses imposed by impact, rollover and static loads of present day aircraft without damage to the fixture or to aircraft and vehicle tires.

It shall be fitted with a pressure relief plug to allow pressure testing.

The fixture shall be suitable for installation in the pavement surface in a 12" cast aluminum shallow (150mm max) base, type ZM480 or in 12" FAA L868 deep canisters.
