Why autonomous third-party (recognized by ICAO and the FAA) Impact Test is required for airport Frangible Structures?
Full impact test is a crucial testing parameter for any
frangible structure installed nearby Runway. As per ICAO, High-speed,
full-scale testing is a proven method for verification of frangibility. Dynamic
tests are recommended for verification of frangibility of navigational aids
having an overall height in excess of 1.2 m and located in positions where they
are likely to be impacted by an aircraft in flight.
Full Impact test as per below International Compliance
International Civil Aviation Organisation(ICAO) Aerodrome Design Manual DOC
9157AN/901 Part 6- Frangibility Subsection 4.9.20. 4.9.21 and 4.9.22
U.S. Department of Transportation , Federal Aviation Administration (FAA),
Advisory Circular No 150/5345-45, Section 3.9 and 4.2.5
It is essential that frangibility tests are conducted and
certified under supervision of an autonomous third-party (ICAO & FAA) like
NLR and Intertek.
