  • THR - runway threshold light
  • END - runway end light
  • TWY - taxiway edge light
  • heliport lighting system FATO, TLOF, HAPP, TWY
  • unserviceability light

Certificate basis

  • ICAO AERODROMES ANNEX 14 Volume I-4rd
  • FAA AC 150/5345-46B

Description/Properties

  • primary outlets are lead out at the bottom part of the aluminum case through the light support
  • optical system and integrated insulating transformer imbedded in aluminum case form 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
