A device to guide a pilot safely to the helipad on a fixed route 。 The basic visual approach slope indicator has two sets of lights：One set is set at the beginning of the run；The other group was located seven meters away from the front lights 。When the lights are viewed from different angles or distances,red or white colors can be seen。If the pilot’s approach angle is correct, the first group light is white and the rear group is red. If the two groups of lights are white, it indicates that the angle of aircraft approach is too high; if both groups of lights are red, it means that the aircraft height is too low.
The high and low angles of light can be from 0 ° to 30 °. Using 12v~50w halogen lamp, the red high-low angle is 5 °, the green high-low angle is 2 ° and the Yellow high-low angle is 5 ° the most important landing navigation instrument on the apron to provide accurate information on whether the landing height is appropriate or not.
The radiator is equipped with heat sink, which can dissipate the heat generated by the luminescence and prolong the service life of the luminaire.
50 mm, 1:3.2 lens, light diffusion in the horizontal direction is 28 ° Normal visible range of light intensity at night: more than 6 km.
The high and low angles of light can be from 0 ° to 30 °. Using 12v~50w halogen lamp, the red high and low angle is 5 °, the green high and low angle is 2%, and the yellow high and low angle is 5。
Overview of flight aid lighting on helipad: it is an engineering facility in and near the helipad flight area to provide pilots with visual guidance signals for takeoff, approach, landing and taxiing day and night. It is generally composed of pavement signs, navigational lights, signboards, signs, etc. Its complexity and simplicity and layout form are based on the plane layout of the apron. It is determined by flight volume, meteorological standard of receiving aircraft and content and precision of radio navigation facilities used together.
