unobstructed area readily visible to helicopters approaching the helicopter
deck should be provided.
13.4.2 The helicopter deck should be marked (figure
2) in a contrasting colour as follows:
-
.1 the perimeter with a continuous line of 40
centimetres width;
-
.2 unit identification; and
-
.3 aiming circles, taking into account deck configuration,
helicopter type and operational requirements.

yellow, and blue lights in alternate order to enable the landing area
to be easily identified at night. These lights should be positioned
around the perimeter of the deck not more than 3 metres apart.
