Product Overview

Description

ZS500 Precision Approach Path Indicator

The LED Visual Approach Slope Indicator (VASI) is used to guide aircraft to approach

the runway at an appropriate altitude. It is specially designed to accommodate the helicopter's steep angles of descent and deliberate speeds. There are three Colors which to show three wide horizontal beams in different colored light. And it is projected in fan shaped array into the incoming flight pattern. The top beam is yellow which indicates a too high altitude of approach; The center beam is green which is the correct altitude; The lower beam is red which indicates a too low altitude. By staying within the green light beam that is correct altitude.

It ensures a safe landing, allowing the pilot to determine correctly the approaching direction and descent angle during both day and night-time.

The LED lamp is of very high intensity and has a rated life of at least 75,000 hours. It is powered by 110 volts or 220 volts AC current with a frequency range from 50 to 60Hz. The LED lamp consumes a tenth of the power of the regular halogen bulb, which creates a big saving in power consumption.

The optical surface is designed so that ice, dirt, and condensation would interfere as little as possible with the light beam.

  The VASI is normally placed on the border of the safety area on the near side, adjacent to the intended touchdown point of a runway or helipad and face into the landing pattern. It is constructed of heavy cast aluminum that is weather tight and finished in an orange polyester power coating.

 

Features:

• LED technology, low-energy and environment friendly lighting fitting , 95% less power than equivalent incandescent light

• Power supply available in AC(110V, 240VAC), DC48V, DC24V or others

• Outstanding photometric performance.

•Unique designed polycarbonate lens for converging light and also provides corrosion resistance and UV protection.

• UV protection Powder coated anti glare yellow color body make better visibility and withstand the harshest climate conditions and dirt

• Front hardened glass protecting lenses against sand, wind and engine blast.

• Base material is stainless steel which has strong corrosion resistance, Shock and Vibrations protection

• Fragile coupling reduce the secondary damage to helicopters effectively

• Easy site adjustment by using an inclinometer (precision 1 minute).

• Design ensures water-tightness and protection against corrosion.

• Easy maintenance: replacement of main elements (lamps, front glass, filters or reflectors) does not require either unit adjustment or any special tools.

• Very easy access to all components by removing the cover.

• Infrared LED for pilot using NVG(Night Vision Goggles)

•Dust proof LHA is standard. Enhances lamp life, improves photometric performance and reduces maintenance cost.

• No optical bench or special tools required for servicing. Special access doors speed lamp changes in the field.

• Controller for power supplying and turn ON/OFF light

• VHF pilot to ground remote control

• Stainless steel Fasteners
