Exel Frangible Carbon Composite Glide Path Towers
Maximized Operation Safety with Unique Structure
Exel Composites Plc has developed a unique range of composite lattice towers and glide path towers which have been delivered over thousand airport installations since 1988.
New composite GP tower design has been developed to provide the user outstanding benefits:
- Very lightweight structure with carbon fibre composite material
- Frangible lattice structure and frangible guy rods
- Slim outlook
The stability and displacement requirements of the tower are guaranteed with composite guy rods and very stiff carbon composite lattice structure.
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.
Glide Path Tower
The Glide Path Tower is supplied in three lattice sections, which can be customised to meet installation requirements.
- The tower can be easily assembled on the ground, including the antennas
- Foundation bolts and casting template can be delivered in advance
- Fully assembled tower can be raised with or without crane
GP-Tower Delivery Includes:
- Foundation bolts and casting template
- Lattice sections for on-site assembly of tower sections
- Antenna brackets that allow adjustment of antennas in three directions
- Frangible guy rods
- Cable conduits
- Obstruction light
