Frangible - adjective : easily broken; breakable; fragile; brittle
Glass is brittle by its nature. It will break at impact. The frangible EXEL mast will cause only minor damage if an aircraft hits the masts. The frangibility of Exel safety approach light masts is full scale tested under supervision of an ICAO organ and the masts are acknowledged to be frangible based on results of the said full-scale test.
EXEL masts are painted in Aviation Yellow colour and serve also as a visual aid for the aircraft pilot when he is landing during daytime in good visibility.
EXEL masts themselves are transparent to electromagnetic signals and do not distort the beam pattern of ILS, which means less need for cumbersome recalibrating of the ILS antenna system.
Versatile modular masts
Distance Coded Centre Line (Calvert) or Barette Centre Line (Alpa-Ata) is designed with masts of standard modular parts. Please ask us to design EXEL Safety Approach Mast System to suit your Airport's specific need. Design Guide is also available.
