Heliport navigation lighting settings

Heliport beacons should be set up at heliports when long-distance visual guidance is required and no other visual method can provide it, and when identification of the heliport is difficult due to the presence of surrounding lights.

Heliport beacons should meet the following requirements:

1. Heliport beacons must be set up in or near the heliport, preferably at a high altitude, and so that pilots are not dazzled at close range. If heliport beacons dazzle pilots at close range, they can be turned off during the final stage of approach and during landing, or the light intensity of the beacon can be lowered to 10% or 3%.

2. The heliport beacon must continuously emit a series of intermittent short white flashes.

3. The light emitted by the beacon must come from Visible in all directions.

The lighting settings of the heliport are in accordance with the provisions of "MH-5013-2008":

1. Airport size: When used by performance level 1 helicopters, the size of the final approach and take-off area should be determined according to the regulations in the helicopter flight manual. If there is no specified width, the width should not be less than 1.5D, and the water heliport should be increased by 10%; when used by level 2 and level 3 performance helicopters, the final approach and take-off area should be able to contain a circle with a diameter of not less than 1.5D, and for a water heliport, it should be able to contain a circle with a diameter of not less than 2.0D.

2. The heliport must set up at least one wind vane. The wind vane must be able to indicate the wind conditions above the approach and take-off areas without being affected by nearby objects or helicopter rotor downwash (downwash).

3. Aiming point mark. When it is necessary for the helicopter to approach a specific location before entering the landing and departure area, the aiming point mark should be set up at the heliport. The aiming point mark should be located in the final approach and take-off area, in the shape of an equilateral triangle, with the bisector of one corner consistent with the main approach direction. The mark should be a continuous white line with a side length of not less than 9 meters and a line width of 1 meter.

4. The heliport identification mark should be represented by the white letter "H". The size of the sign shall not be less than 3 meters.

5. Final approach and take-off area lights. Surface heliports used at night must be equipped with final approach and take-off area lights; but when the final approach and take-off area almost coincides with the touchdown and departure area or the scope of the area is obvious, the lights must be installed along the final approach and take-off area. The edges should be set evenly. If the area is square or rectangular, the distance between the lights should not be greater than 5m, and no less than 4 lights should be installed on each side (including lights on each corner); if the area is of other shapes (including circles), the distance between the lights should not be greater than 5m, and at least 10 lights should be installed. Final approach and take-off area lights should be omnidirectional with a constant white glow. lamp.

6. Aiming point lights. If there is an aiming point mark at a heliport for night use, aiming point lights should be set up. The aiming point lights must be set together with the aiming point mark. Aiming point lights should be all white lights, at least 6 should be set. When lights higher than the surface will endanger the operation of the helicopter, recessed lights must be used.
