Composite  Glide Path Tower - 1

Composite Glide Path Tower ICAO’s Frangibility Ruling AERODROME DESIGN MANUAL PART 6, Frangibility — First Edition, 2006 states that: ...certain airport equipment and installations, because of their function, must be located in an operational area. All such equipment and installations as well as their supports should be of minimum mass and frangible in order to ensure that impact does not result in loss of control of the aircraft. Among these equipment are for example: • ILS glide path equipment …structures located within the grated portion of the runway strip not meeting the frangibility requirement, such as an existing non-frangible ILS glide path antenna, should be replaced by a frangible structure, if practicable, and relocated within the non-grated portion of the runway strip. Exel Fibre Glass Composite Towers Exel Composites Oyj have developed a unique range of fibre glass lattice towers which have been delivered to airport installations since 1988. Fibre glass is a lightweight material that brakes at impact and is transparent to electro-magnetic signals. It tolerates all types of weather and is practically maintenance free. • GP tower is supplied in sub-assemblies. The tower is easily assembled laying on the ground. • Anchor bolts and casting template are delivered in advance for preparation of the foundation. • Antennas, ladder and life-line installed on the ground. • Fully assembled tower raised with a crane.

ADM6: 4.9 Design Criteria for Frangibility 4.9.31 ILS/MLS installations present special cases. The requirements of 4.9.24 to 4.9.30 are applicable for ILS/MLS structures, but the design criteria associated with a 3000-kg airplane cannot be applied in all instances for the following reasons: B) Considering the unique nature of the tower structure the ILS glide path antenna, frangibility criteria have not yet been developed.
