CS HPT-DSN.F.590 Helicopter ground taxiway markings and markers ED Decision 2019/012/R (a) Applicability: (1) The specifications for runway-holding position markings defined in [CS ADR-DSN.L.575](#_DxCrossRefBm1800047690) and for intermediate holding position marking defined in [CS ADR-DSN.L.580](#_DxCrossRefBm1800047693) are equally applicable to taxiways intended for ground taxiing of helicopters. (2) The centre line of a helicopter ground taxiway should be identified with a marking. (3) The edges of a helicopter ground taxiway, if not self-evident, should be identified with markers or markings. (b) Location: (1) Helicopter ground taxiway markings should be along the centre line, and, if provided, along the edges of a helicopter ground taxiway. (2) Helicopter ground taxiway edge markers should be located at a distance of 0.5 m to 3 m beyond the edge of the helicopter ground taxiway. (3) Where provided, helicopter ground taxiway edge markers should be spaced at intervals of not more than 15 m on each side of straight sections and 7.5 m on each side of curved sections with a minimum of four equally spaced markers per section. (c) Characteristics: (1) A helicopter ground taxiway centre line marking should be a continuous yellow line 15 cm in width. (2) Helicopter ground taxiway edge markings should be a continuous double yellow line, each 15 cm in width, and spaced 15 cm apart (nearest edge to nearest edge). (3) A helicopter ground taxiway edge marker should not exceed the height of a plane originating at a height of 25 cm above the plane of the helicopter ground taxiway, at a distance of 0.5 m from the edge of the helicopter ground taxiway and sloping upwards and outwards at a gradient of 5 per cent to a distance of 3 m beyond the edge of the helicopter ground taxiway. (4) Helicopter ground taxiway edge markers should be frangible to the wheeled undercarriage of helicopters. (5) A helicopter ground taxiway edge marker should be blue. (6) If the helicopter ground taxiway is to be used at night, the edge markers should be internally illuminated or retro-reflective.
