12.2 Factors to be considered before using a helicopter landing site Hazardous trees, as defined in the Forestry Code, within two dominant tree lengths of the landing site should be removed before the helicopter landing site (HLS) is used. The pilot of a helicopter operating to, from or at the HLS should ensure: the HLS is clear of: people not essential to the helicopter operation objects and animals likely to be a hazard to manoeuvring the helicopter—other than objects essential to the helicopter operation, and no person outside the helicopter—other than a person essential to the operation—is within 30 metres of the helicopter (see Figure 12). A helicopter must not land at, or take-off from a HLS located within controlled airspace without clearance from the air traffic controllers. If a proposed HLS is to be located near a city, town or populated area where noise or other environmental considerations make helicopter use undesirable, the HLS may be affected by the Commonwealth Environment Protection Act and associated State-based legislation. Basic helicopter landing sites A basic HLS should: only be used for infrequent, opportunity and short term operations in daylight hours be large enough to accommodate the helicopter safely have a surface capable of withstanding the static and dynamic loads imposed by the helicopter e.g. twice the gross weight of the helicopter not exceed the maximum slope landing capability of the helicopter—generally 7.5 degrees or 1:8 vertical to horizontal have an air taxiing route at least three times the width of the main rotor diameter, and have a means of earthing the helicopter e.g. an earth stake. Figure Basic helicopter landing site Standard helicopter landing site A standard HLS is intended to be used for day and night operations. A standard HLS should comply with the following guidelines: The final approach and take off area (FATO) at a minimum, should have a circular area with a diameter equal to twice the length of the helicopter when the rotor(s) are turning (2 x L), which is free of obstacles likely to interfere with the manoeuvring of the helicopter. The ground effect area (GEA) at minimum, should have either a circular area with a diameter equal to the diameter of the main rotor of the helicopter, or if the helicopter is of the tandem rotor type, the GEA should be a rectangular area equal to the length of the helicopter and the width equal to the rotor diameter.
