BC / BM FRANGIBLE COUPLING AND MASTS

FRANGIBLE COUPLINGS

Related Standards

  • FAA AC 150/5345-46 Para. 3.4.2.1

APPLICATIONS

  • Airfield lights are mounted on frangible couplings which are designed to break at a defined force. Their use protects the integrity of the unit itself and minimizes damage to the object that strikes it.

IMPORTANT FEATURES

  • Couplings have a designed yield point, therefore they should be used with the light they are designed for. Failure to do so will result in the coupling not working properly
  • Frangible couplings allow repairs to take place in minimal time.

FRANGIBLE MASTS

Related Standarts

  • FFAA AC 150/5345-45

  • ICAO Annex 14 Vol. I Para. 5.3.1.4

APPLICATIONS

  • Frangible Masts are support structures for elevated approach lighting that break or yield on impact, to minimize damage airplanes and maximize safety

IMPORTANT FEATURES

  • Frangible masts are very lightweight, yet rigid structures that break or yield on impact,
