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 distance of 0.25 times the D value of the design helicopter before the shoulder bar marking on the side of the approaching helicopter; and

(b) with the left-hand edge of the required text aligned with the right-hand side of the shoulder bar; and

(c) with the designator letters and numbers:

 (i) marked 1 m high in yellow; and

 (ii) as far as physically possible, drawn to reflect, in form and width, the same proportions as shown for the letters and numbers in Figure 8.116 (5); and

 (iii) clearly readable by the pilot of an approaching helicopter.

       (5) If it is necessary to restrict the weight capacity of the helicopter parking position, a weight limit designator must also be marked:

(a) at a distance of 0.25 times the D value of the design helicopter after the shoulder bar marking on the opposite side to the approaching helicopter; and

(b) with the right-hand edge of the required text aligned with the left-hand side of the shoulder bar; and

(c) with the designator letters and numbers:

 (i) marked 1 m high in yellow; and

 (ii) as far as physically possible, drawn to reflect, in form and width, the same proportions as shown for the letters and numbers in Figure 8.116 (5); and

 (iii) clearly readable by the pilot of an approaching helicopter.

Note   If the helicopter parking position can also be accessed from the reciprocal direction, the shoulder-line type parking position can be marked as bi-directional by using 2 shoulder lines — 1 for each approach direction. If a bi-directional parking position is marked, CASA recommends that care should be taken to ensure any associated D value limit or weight limit markings for each shoulder line do not overlap with the markings for the reciprocal direction.

8.124 Helicopter parking position markings — touchdown/positioning circle type

       (1) If a helicopter parking position requires a turn by the helicopter to enter and leave the parking position, then a touchdown/positioning circle (T/PC) type helicopter parking position marking is required.

       (2) A T/PC type helicopter parking position must be marked by a circle, as shown in Figure 8.124 (2):

(a) with a diameter of 0.5 times the D value of the design helicopter; and

(b) with a line thickness of 0.5 m; and

(c) whose centre is aligned with the centroid of the design helicopter when it is correctly parked on the position.

       (3) If it
