CS HPT-DSN.F.610 Helicopter stand markings

(a)Applicability:

(1)A helicopter stand perimeter marking should be provided on a helicopter stand designed for turning. If a helicopter stand perimeter marking is not practicable, a central zone perimeter marking should be provided instead if the perimeter of the central zone is not self-evident.

(2)For a helicopter stand that is intended to be used for taxi-through and which does not allow a helicopter to turn, a stop line should be provided.

(3)Alignment lines and lead-in/lead-out lines should be provided on a helicopter stand (see Figures F-4 and F-5).

(b)Location:

(1)A helicopter stand perimeter marking on a helicopter stand designed for turning or, a central zone perimeter marking, should be concentric with the central zone of the stand.

(2)For a helicopter stand that is intended to be used for taxi-through and which does not allow the helicopter to turn, a stop line should be located on the helicopter ground taxiway axis at right angles to the centre line.

(c)Characteristics:

(1)A helicopter stand perimeter marking should be a yellow circle and have a line width of 15 cm.

(2)A central zone perimeter marking should be a yellow circle and have a line width of 15 cm, except when the TLOF is collocated with a helicopter stand, in which case the characteristics of the TLOF perimeter markings should apply.

(3)For a helicopter stand that is intended to be used for taxi-through and which does not allow the helicopter to turn, the yellow stop line should not be less than the width of the helicopter ground taxiway and should have a line thickness of 50 cm.

(4)Alignment lines and lead-in/lead-out lines should be continuous yellow lines and should have a width of 15 cm.

(5)Curved portions of alignment lines and lead-in/lead-out lines should have radii appropriate to the most demanding helicopter type the helicopter stand is intended to serve.

(6)Stand identification markings should be marked in a contrasting colour so as to be easily readable.

(7)Where it is intended that helicopters proceed in one direction only, arrows indicating the direction to be followed may be added as part of the alignment lines.
