## CS HPT-DSN.F.590 Helicopter ground taxiway markings and markers

(a) Applicability:

(1) The specifications for [runway-holding position](https://avioverse.aero/glossary/easa/runway-holding-position) markings defined in CS ADR-DSN.L.575 and for [intermediate holding position](https://avioverse.aero/glossary/easa/intermediate-holding-position) [marking](https://avioverse.aero/glossary/easa/marking) defined in CS ADR-DSN.L.580 are equally applicable to taxiways intended for ground taxiing of helicopters.

(2) The centre line of a [helicopter ground taxiway](https://avioverse.aero/glossary/easa/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](https://avioverse.aero/glossary/easa/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.
