8.121 (3), only a single helicopter parking position is provided in conjunction with the final aircraft parking position designator. In this case, only the prefix would be required. If more than 1 helicopter parking position or another aircraft parking position is provided on the aerodrome, then the helicopter taxi guideline designation would be designated in this example as H7. This is because "7" is the next parking position in the sequence. Subsequent helicopter parking positions would then need to be marked H8, H9 and so on. Any subsequent aircraft parking positions would need to be numbered sequentially using the same number sequence but without using the "H" prefix.

       (6) If a taxi guideline leads to multiple parking positions, the first and the last parking position in the range may be marked and separated with a dash, for example, H7 – H9.

       (7) Helicopter taxi guideline designations must be located and oriented so that they can be seen 15 m away by an aircraft or helicopter on the taxi guideline.

8.122 Helicopter parking position designation markings

       (1) If a dedicated helicopter parking position is provided on a sealed, concrete or asphalt apron, the parking position must be designated.

       (2) The parking position designator must be marked with the prefix letter "H",  yellow and 2 m in height with a line thickness of 0.3 m.

       (3) If more than 1 helicopter parking position is provided, the prefix must include the parking position number in sequence with aircraft parking positions and helicopter taxi guidelines.

       (4) The parking position designator must be located before the helicopter parking position marking, at a distance of 0.83 times the D value of the design helicopter for which the aerodrome is designed (the design helicopter), facing the approaching helicopter.

8.123 Helicopter parking position markings — shoulder-line type

       (1) If a helicopter parking position requires no turn by the helicopter to enter and leave the parking position, then a shoulder-line type helicopter parking position marking must be provided.

       (2) As shown in Figure 8.123 (2), a shoulder-line type helicopter parking position marking must be:

(a) a transverse yellow bar, marked at right angles to, and bisected by, the taxi guideline; and

(b) 0.5 m wide; and

(c) of a length that is 0.5 times the D value of the design helicopter.

       (3) The transverse bar must be aligned with the position of the pilot's shoulder when the design helicopter is correctly parked on the position.

       (4) If it is necessary to restrict the size capacity of the helicopter parking position, a D value limit designator must also be marked:

(a) at a
