Airport Lighting Specialists

PAL - Permanent Airport Lighting

threshold / end light

PAL is the most commonly found light on Australian airstrips. PAL is not only approved by the CAA, it was developed in a joint effort between CAA (or Department of Aviation as they were then known) and Artcraft Engineering. Airport Lighting Specialists are now the manufacturer and have manufactured PAL lights in Melbourne (Australia) since 1997.

PAL lights are lightweight yet strong. An early version of the PAL (V7/913) was approved by Department of Aviation in 1972. An upgraded version (V7/1222) was approved without restriction in 1982.

PAL threshold / end

When the Manual of Standards (MOS139) superceded the Rules & Practices for Aerodromes the performance requirements for threshold/end lights changed. None of the existing threshold/end lights in the market complied to the new regulations. In order to make the MOS139 upgrade as painless as possible, Airport Lighting Specialists developed a new lens that can be quickly and easily fitted to existing PAL fixtures resulting in fully compliant threshold/end lights.
  

PAL lights can be manufactured in a number of different configurations to accommodate a variety of different lamps. The more recent Australian installations tend to use 6.6 Amp lamps, in either G6.35 or P28 configuration. Older Australian airstrips tend to use 4.0 Amp BA20 lamps. See exploded diagrams of PAL light in G6.35 and BA20 configuration.
