Frangible Mast
The frangible mast is made of a glass fiber tube. The same mast tube
structures are also used in the approach light systems of several airports
around the world. The mast manufacturer Exel has performed frangibility
tests under the supervision of ICAO (International Civil Aviation
Organization ). Reports of these tests are available on special request.
The grounding cable inside the mast is connected to the mast with a fork
type connector. The connector will slide from its attachment screw in
case of an impact to the mast. The measurement unit cable will also slide
through its cable gland in FSI102 and disconnect from the FSC202 in
case of an impact to the mast.
