Light fixture function

  • APP approach centre line and crossbars light
  • THR runway threshold light
  • END runway end light
  • THREND threshold/runway end light
  • RWY runway edge light
  • TWY taxiway edge light

Certificate basis

  • ICAO Annex 14, Vol. 1, 7th ed.
  • FAA AC 150/5345-46, photometrically compatible with L-861/861T
  • AIR STD 90/20 Portable Airfield Lighting Systems, released ASCC
  • MAK


  • bidirectional light characteristic with one main beam of light or two opposite main beams of light
  • precise positioning and directing of optical unit is ensured by fixation pins located with transformer aluminium cover
  • primary outlets are lead out at the bottom part of the aluminum case through the light support and through the breakable coupling above the disk that enable disconnection of the lighting marker in case of a collision with an aircraft of vehicle
  • optical system and integrated insulating transformer imbedded in aluminum case from one unit
  • the lights are made of castings and formed pieces of aluminium alloys, a glass formed piece and connecting stainless steel parts that are resistant to salty environment and UV radiation.  
  • support is an aluminium casting to which the marker is fixed
  • it also serves as fixing of the light in the tube to the breaking coupling
  • the colour dioptres are made of glass resistant to thermal shocks
  • the glass dioptre is sealed in an aluminium annular ring and this unit is tied to the aluminium cover using two stainless steel clips
