Approach light AL-056-08-WH

for heli-platformsLEDflashing

The Heliport APPROACH lights are steady and flashing omnidirectional white lights. According to ICAO ANNEX 14, volume II, an approach lighting system should be provided at a heliport where it is desirable and practicable to indicate a preferred approach direction. These lights should form a cross to create the Approach lighting system. The approach lighting system is a row of three lights at 30 m intervals and a crossbar of five lights on 18 m at a distance of 90 m from the perimeter of the FATO. Where there is the need to make the final approach course more conspicuous, additional lights spaced uniformly at 30 m intervals should be added beyond the crossbar. The lights beyond the crossbar may be steady or sequenced flashing, depending upon the environment. The mounting system is elevated, fixed on a base plate with a frangible coupling The casing is made of powder-coated aluminum The diffuser is made of clear polycarbonate UV protected Electrical characteristics The power supply can be a heliport controller. In this case, the control is also made in three steps from the heliport controller. Power input can be low voltage, 48 V DC or it can work in constant current when the distance from the heliport controller to the lights is long and this will generate a big drop of voltage on cables. Optionally it can be powered at 90-230V, 50/60Hz but the light fixtures will no longer have the dimming function If the sequenced flashing is needed then a flashing controller must be added to the control system Environment APPROACH elevated lights were tested for working environments from -50 to + 50 °C The degree of protection is IP 67
