FLIGHT MANUAL
.
4 NORMAL PROCEDURES
The normal procedures laid down in the basic Flight Manual remain
applicable but are c~leted by the following procedures.
Carring heavy loads is a delicate operation, due to the possible effects
of a swinging load on the flight behaviour of the helicopter. Consequently,
pilots are advised to train with gradually increased sling loads before
undertaking heavy load carrying operations.
~ : IN WET WEAnlER, nlICK RUBBER GLOVES SHOULD BE WORN BY THE
OPERATOR HANDLING THE HOOK AND LOAD. RELEASE THE CHARGE OF
STATIC ELECTRICITY BY PLACING AN ELECTRICAL CONDUCTOR CABLE
OR TUBE BETWEEN THE GROUND AND THE CARGO RELEASE UNIT (Hook).

-Check of the installation
-On the ground, before carrying out a load transport operation:
.Check that the hook opens correctly both in normal and jettison
control modes.
.Zero the load indicator.
.In flight, press the "SLING" pushbutton in order to set the system in
readiness for normal release of the load which will be accomplished by
actuating the rocker-switch on the cyclic stick control grip.
-~ '
.When the load is secured, apply collective pitch very smoothly,
while maintaining the aircraft directly above the load. When the cables
are taut, dwell briefly before raising the load.
.Lift the load off the ground vertically, keeping a watch on the load
indicator, then move off in a forward clint!.
-Manoeuvres
All control movements should be made very gently, with very gradual
acceleration and deceleration, and only slightly banked turns.
