through the cargo compartment floor hatch to pull up the extension cable

(6) A ground technician should engage the extension cable hook with the ex-
ternal load slings pivot ring, with the slings snap hooks being previously
connected to the load fittings. After the hook attached to the helicopter
winch cable touches the ground connect it to the extension cable lug,
give a signal to the Flight Engineer indicating that the load is attached
and move 25 to 30m away from the load.
(7) The Flight Engineer, after receiving the ground technician's signal indicat-
ing attachment of the load, should pull in the helicopter winch cable with
the extension cable attached to it and connect the extension cable lug to
the Ar-64 shackle, disconnect the helicopter winch cable hook from the
extension cable lug, and report to the Captain about the load readiness
for lift.
(8) The Captain, after receiving the Flight Engineer's report, should check the
Ar-64 shackle for closed position indicated by going out of the SHACKLE
OPEN (3AMOK OTKPbIT) annunciator, and slightly lift off the helicopter
to execute a small shift towards the load so as the distance from the main
LG wheels to the load is 1 to 2m.
(9) In the course of shift and transition to hovering above the load the Flight
Engineer observes the load through the cargo compartment hatch and
corrects the pilot's actions by transmitting short orders through the inter
phone system in which he indicates, apart of the direction, approximate
distance and height (0.5 m back, 1 m down, etc.).
(10) On hovering above the load smoothly move up the collective pitch control
lever to increase the helicopter hovering altitude until the external load
sling system cables are completely pulled up.
Keep the helicopter strictly above the load and avoid longitudinal and lat-
eral shifts (following the Flight Engineer's orders).
(11) After the external load sling system cables are completely pulled up
smoothly move up the collective pitch control lever to advance power up
to takeoff and lift the load off the ground to clear it not less than 3 m from
(12) Make sure the load behavior in hovering is normal and the load clearance
from the ground is not less than 3 m for safety reason in acceleration,
push smoothly the control stick forward to establish forward speed. If
transition from hovering to forward flight is executed smoothly the
helicopter does not practically lose altitude.
(13) On attaining a speed of 100 km/h lAS, climb and reduce the engine
power to the maximum continuous power rating.
When transporting the external load, execute maneuvers (such as accel-
eration, deceleration and turns) smoothly and slowly to avoid swinging of
the load.
Behavior of the external load is dictated mainly by its aerodynamic con-
figuration. Therefore, in the initial stages of flight, select such condition of
flight by changing the speed at which behavior of the external load is
most quiet. But it is necessary to bear in mind that the fuel consumption
per kilometer will reduce with speed rising up to the best one.
(14) The Flight Engineer should monitor behavior of the external load in flight
through the cargo compartment blisters.
