Elevated Approach for ground level heliports

Elevated Approach

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.

Description

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
The total power is just 15W
If the sequenced flashing is needed then a flashing controller must be added to the control system

Environment

APPROACH heliport elevated lights were tested for working environments from -50 to + 50 °C
The degree of protection is IP 67
The exposed surface to the wind is low so it can withstand strong wind
UV protected polycarbonate makes it resistant to sun radiation

Optical characteristics

The light source is made with WHITE LEDs and special lenses to obtain the ICAO specifications
The color and lights distribution passes the tests according to ICAO into an external recognised laboratory
The expected lifetime for LEDs is more than 100000 working hours
