According to the relevant regulations of the Civil Aviation Administration of China and the International Civil Aviation Convention Organization, visual navigational lighting equipment must be installed on the helicopter apron to better ensure the safety of helicopter takeoff and landing. Ground and departure area lights: Ground and departure area lights must be set along the boundary of the ground and departure area or within a distance of no more than 1.5m from the boundary. For surface heliports, their spacing should not exceed 5m; For elevated heliports and helidecks, the spacing should not exceed 3 meters. At least 4 lights should be installed on each side (including the lights on each corner). When the grounding and off zone is circular and the lights are evenly arranged along the perimeter, at least 14 lights should be installed. This lamp must emit green light! Final approach and takeoff area lights: For surface heliports used at night, final approach and takeoff area lights must be installed. The lighting fixtures must be uniformly set along the edge of the final approach and takeoff area. If the area is square or rectangular, the spacing between the lights should not exceed 5m, and no less than 4 lights (including lights at each corner) should be set on each side; If the area is of other shapes (including circles), the spacing between lights should not exceed 5m, and a minimum of 10 lights should be set up! The final approach and takeoff area light should be a constant white emitting omnidirectional light, but when the final approach and takeoff area almost coincides with the touchdown and takeoff area or the range of the area is obvious, this type of light may not be installed. Aiming lights: In order for helicopters to better identify the aiming point, heliports used at night need to set up aiming lights, and the aiming lights must be set together with the aiming point sign. Aiming point lights should be all white and at least 6 should be set. When lights above the surface pose a threat to helicopter operation, embedded helicopter apron lights must be used. Floodlights: The position of the floodlights should not make the pilot or TLOF staff feel dazzled. The arrangement and direction of floodlights should minimize shadows. The height of floodlights shall not exceed 25 cm. The spectral distribution of floodlights should enable correct identification of surface markings and obstacle markings. The average horizontal illuminance of floodlight measured from the TLOF surface should not be less than 10 lx, and the uniformity ratio (ratio of average to minimum) should not be greater than 8:1 heliport beacon: In the following situations, heliports should be equipped with heliport beacon: - remote visual guidance is required, and no other visual method can provide it—— Due to the presence of surrounding lights, it is difficult to identify a heliport. The heliport beacon should meet the following requirements: 1. The heliport beacon must be installed inside or near the heliport, should be elevated, and should ensure that the pilot does not feel dazzled at close range. If the heliport beacon makes the pilot feel dazzled at close range, it can be turned off during the final stage of approach and landing, or the intensity of the beacon can be lowered to 10% or 3%. The heliport beacon must continuously emit a series of equally intermittent white flashes. 3. The light emitted by the beacon must be visible from all directions
