1.0 General
1.1 The following sections outline the requirements for helicopter landing area markings which should be permanantly painted on the deck. Plans of the marking arrangements including dimensions should be submitted to the Aviation Inspection Body for approval.
1.2 Helicopter landing area perimeter line marking and lighting serves to identify the limits of the Safe Landing Area (SLA) for day and night operations.
1.3 A wind direction indicator (windsock) should be provided during helicopter operations and located so as to indicate the clear area wind conditions at the vessel location. It is often inappropriate to locate the windsock as close to the helicopter landing area as possible where it may compromise obstacle protected surfaces, create its own dominant obstacle or be subjected to the effects of turbulence from structures resulting in an unclear wind indication. The windsock should be illuminated for night operations.
