High Wind Conditions - Helicopter Mooring
When severe storm conditions or wind velocities higher than 40 knots are forecast,
helicopter should be hangared or evacuated to a safe area. If the helicopter must
be parked in the open during high winds, comply with the following.
Structural damage can occur from flying objects during high wind
conditions. Helicopter should be hangared or evacuated to a safe
weather area when wind conditions above 75 knots are expected.
If a paved ramp with tiedown rings are available, park helicopter headed in
direction from which highest forecast winds are expected.
Secure helicopter to ramp tiedowns using forward and aft tiedowns (Ref.
Figure 8-2).
If a paved ramp with tiedown rings are not available, park helicopter on an
unpaved parking area, headed in the direction from which highest forecast winds
are expected.
Install blade tiedowns.
Tiedown rotor blades, whenever helicopter is parked, to prevent
rotor damage from blade flapping as a result of air turbulence from
other aircraft or wind gusts. The maximum blade tie down load
is when the blade tip just begins to deflect downward.
Install engine area cover (Ref. Figure 8-2), and pitot cover.
Fill fuel cell, if possible.
After winds subside, inspect helicopter carefully for damage which may have
been inflicted by flying objects.
