The roof deck elevated helipad, helipad Technical Note

        The so-called roof of an elevated helipad on the roof does not draw an H-shaped, and put on some aviation lighting, and fence even a roof helipad, which is wrong.

        The helicopter deck landing is a kind of high-rise or high-tech, highly difficult movements, unless the elevated deck helipad helipad by professional engineers designed, and its ramp is equipped with full compliance with the CAAC and the International Civil Aviation Organization ICAO Article 14 Subsidiary Book Volume II norms, or to complete the construction of the ramp will not only receive less than the competent authority issued by the Civil Aviation helicopter market permits, and all helicopter pilots almost afraid to use this ramp to take off and land without a license, helicopters, especially in the unlicensed aerodromes flight safety incident occurs, the captain would be severely punished.
        Navigation lights into the general airport use and private heliport two, a lot of people would normally use the airport lights installed in the helicopter Pingshang wrong, it is not in conformity with helipad norms. Night light wind vane (wind sock) is also divided into two kinds of ground-and roof type, specification size have a certain standard, necessary heliport beacon light, which is the rate of double-barreled white flashes 0.8 seconds, 1.2 seconds, 0.8 seconds in accordance with international signaling standard that the same time, it can also meet the driver needs to be reduced from 100% brightness to 10% or 3%. Another ramp edge lights and edge lights are spaced light color and color also has certain norms, side lights elevation 0 ° = 3cd, 5 ° = 15cd, 10 ° = 25cd, 20 ° = 25cd, 25 ° = 15cd, 30 ° = 3cd angle of light required to meet the requirement. The ramp wind direction and route planning for years been an indispensable part of the helipad. In order for helicopter pilots more secure, standards-point landing at aerodromes, the aerodrome landing path of the installation instructions Instrument 』『 are essential part of it. In particular the emergency medical ambulance helipad to fight for a faster limitation, the use of helicopters on the communication radio to automatically open the aerodromes of navigation lights is the emergency medical rescue helicopter equipped aerodromes indispensable one.
         High-rise elevated ramp of its floor surface If RC reinforced concrete irrigation system, its weight of up to several hundred tons of high-rise buildings will not only increase the load, and the roof was too heavy, prone to earthquake risk. And 2-3 years after the ramp floor surface will be cracked, the paint will peel off, very ugly. Therefore, in the design earthquake, such as using steel alloy deck, not only light weight, the weight of one-tenth of RC coagulation, anti-corrosion, ramp novel, durable over sixty years. Helicopter taking off and landing, the building does not shake, and can be appropriate to reduce the noise, ramp safety, aesthetics and modern.
        High-rise elevated helipad, helipad deck of the ship shall be designed in accordance with the site and the surrounding terrain and obstacles to detailed measurement of the environment, for dangerous obstacles that must be close to eye-catching warning aerodromes all signs paint color to be separated from clear, the airfield fire and rescue Equipment to be around the proper location on the helicopter overhead and deck apron approach and departure, the aerodromes shall not stand any staff (including command staff) to avoid being shot down by strong winds on the ground the main rotor. A well-planned peace apron insurable hundred years.
