Helipad on the roof

 

A helicopter landing site is a piece of land that is being erected under a structure for servicing, take-off and landing of helicopters. The sites are divided into permanent and temporary. Constants provide takeoff and landing of the helicopter for a given flight weight, for aircraft, and temporary - for helicopter, that is, vertically. There is also a distribution of sites for the purpose: transport (intermediate, basic and final), training and special applications. The transport VPs are designed to provide cargo and passenger transportation via an air line of local importance. VP special applications are designed for helicopters that perform aviation-chemical, geological and other types of work. They also include medical purpose helicopters.

The composition of elements necessarily inherent to VP are: the working area, the lateral plane limitation, the air strip approaches, taxiways, apron, section CT building and parking.

 

In addition to land the EP can be placed on specially equipped roof of the building, and even LCD. In this case, there is a set of rules and constraints. The first EP on the building located on each undergraduate and 1000 square. m. The roof area of ​​the building. In this case provides an additional output and fencing roof height of at least 1,5 m. This is a necessary condition in order to protect the people from the main flow of the inductive screws.

The size of the site itself is adjusted depending on the size of the building and the helicopter itself, but it should not be less than the indicator 20x20 m. The site is projected to be level and paved in the center of the roof. Not allowed playgrounds tilt excess over 8⁰. The perimeter is colored with a yellow stripe. Width 0,3 m. Above or close to it there should be no antennas, cables, various electrical equipment and the like. The maximum permissible height of obstacles in the radius of 15 m from the center of the site is 3 m, and within a radius of 30 m there should be no protrusions of walls or other obstacles. The calculation of the load for covering the platform takes into account the statistical and dynamic loads. But in this case the calculation is based on the maximum possible number of masses taken to land the helicopter. This is necessary because of the different weights of the different classes of helicopters.

Helipad on the roof should have a metallic composition of the pallet. Parapet deaf, and a height of not less than 0,1 m. Among the required equipment must be stationary automatic installation of foam extinguishing with estimated time of at least 10 minutes.
