control panel, to ON position. The separate throttle control lever of
the operating engine should be latched at the midway position.
Warning: if, with setting idie to one engine, the other engine faiis
to gain an elevated power or horizontal flight with one
engine operating at contingency power proves to be im-
possible, do not shut down one engine. In this case pro-
ceed to flight with two engines operative, for this pur-
pose latch the separate throttle control lever of the en-
gine running at idle at the middle position.
(f) 1 minute after setting the throttle lever of the engine to be shut
down to idle, make sure the Flight Engineer holds the HP fuel shut-
off lever of the same engine, and give him an order to shut down
the engine, and simultaneously apply the control stick and pedals ill
an appropriate way to counteract arising rolling and turning. Out-of-
trim condition due to shut down of one engine is unsignificant and
can be easily alleviated by the flight controls.
(g) Pull the control stick back to decelerate the helicopter down to a
speed of 120 to 130 km/h.

Operate the collective pitch control lever to set a power to the
operating engine at which the helicopter flies without loss of

flying at this speed for 2 to 3 minutes and thereafter start
the previously shut-down engine.
(5) To shut down the engine for training purposes at a low airspeed follow
the procedure below:
(a) At a height of 300 m above the aerodrome the Captain estabiishes
horizontal flight at an airspeed of 70 km/h and calls: "Be ready for
shutdown of left (right) engine". Upon this order the Flight Engineer
prepares the respective engine for shutdown, the Pilot-Navigator in-
creases alertness in monitoring the power plant operation and
maintenance of the main rotor speed.
(b) Move the throttle lever of the engine to be stopped fully down. This
done, the other engine should automatically gain an elevated power
with its throttle lever latched at the middle position.
(c) The Pilot-Navigator notes the time.
(d) Operate the collective pitch control lever to maintain the main rotor
speed within the limits of 95± 2%.
(e) Make sure that the CONTINGENCY POWER (CP) switch, located
on the EEC control panel, is set to ON position. The separate throt-
tle control lever of the operating engine should be latched at the
middle position.
(f) 1 minute after setting the throttle lever of the engine to be shut
down to idle, make sure the Flight Engineer holds the HP fuel shute
off lever of the same engine, and give him an order to shutdown the
engine. Out-of-trim condition due to shut-down of one engine is un-
significant and can be easily alleviated by the flight controls.
(g) Accelerate the helicopter by smoothly pushing the control stick to a
speed of 120 to 130 km/h.
(h) Operate the collective pitch control lever to set the engine power at
which there is no altitude loss.
(i) Continue flying at this speed during 2 to 3 min, and start the previ-
