8.1 Provision should be made for equipment needed
for use in connection with helicopter operations including:
-
.1 chocks and tie-down strops
-
.2 heavy-duty, calibrated, accurate scales for
passenger baggage and freight weighing;
-
.3 a suitable power source for starting helicopters
if helicopter shut-down is seen as an operational requirement; and
-
.4 equipment for clearing the helicopter landing
area of snow and ice and other contaminants.
8.2 Chocks should be compatible with helicopter
undercarriage/wheel configurations. Helicopter operating experience
has shown that the most effective chock for use on helicopter landing
areas is the 'NATO sandbag' type. Alternatively, 'rubber triangular'
or 'single piece fore and aft' type chocks may be used as long as
they are suited to all helicopters likely to operate to the helicopter
landing area. The 'rubber triangular' chock is generally only effective
on decks without nets.
8.3 For securing helicopters to the helicopter
landing area only adjustable tie-down strops should be used.
