Product description
Visual Approach Slope Indicator (VASI) is used to guide helicopter to approach the runway at an appropriate altitude. It is specially designed to accommodate the helicopter's steep angles of descent and fast speeds.
There are three colors to show three wide horizontal beams at different angles. 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 indicates a appropriate altitude, the lower beam is red which indicates a too low altitude.
By staying within the green light beam that is correct altitude.

Features
Stable and reliable structure, high accuracy, convenient use and maintenance.
This device is a visual landing aid light for airports, providing pilots with accurate information on whether the landing altitude is appropriate.
Equipped with heat dissipation fins, it can dissipate the heat generated during illumination and extend the lifespan of the lighting fixture.
The angle range of light can range from 0°to 30°. The angle of the red beam is 5°, the angle of the green beam is 2°, and the angle of the yellow beam is 5°.
When in use, this indicator will project three light curtains in the direction of helicopter landing, divided into red, green and yellow. When the helicopter pilot sees the red light in the air, it indicates that the helicopter is flying at a low altitude and needs to be pulled up; when yellow light is seen, it indicates that the flight altitude is too high and the helicopter must be lowered to safely approach and land according to the green light angle.
Frangible structure design effectively prevents secondary damage to the helicopter.
