4.12.1. Engine Airstart for Training: Purposes
(1) It is allowed to air start the engine for training purposes at altitudes not
exceeding 4000 m.
Before start proceed as follows below:
(a) Make sure the AVl-9BAPU operates normally.
(b) Make sure the throttle lever of the engine to be started is set to the
lower stop,
(c) Establish an airspeed of 120 km/h,
(d) Make sure the compressor rotor of the engine to be started is
windmilling and the autorotation speed does not exceed 7%,'
(e) Make sure the STBY GEN (PE3EPBH,rEHEPATOP) switch is set
to OFF (BbIKll,),
Start the engine following the normal procedure,
Warning: If the gas generator rotor tachometer indicator pointer
fails to move off the zero graduation within 5 seconds
since depression of the starting button, depress the
"START DISCONT" (nPEKPAI.l\EHVlE 3AnYCKA) but-
ton, let the engine cool down for 2 minutes, and perform
cranking of the engine. If during cranking the gas gen-
erator rotor tachometer indicator pointer fails to move off
the zero graduation, do not airstart the engine, continue
flying with one engine inoperative, and land,
(f) After the engine being started attains steady idling speed set the
CONTINGENCY POWER (CP) switch to OFF position,
(g) Check the throttle control twist grip position (turn it to the right most
position),
(h) Set the throttle lever of the started engine to the midway position
and latch,
(i) Check the main rotor speed which should be within the limits of
95± 2%.
Q) Establish a clesiredflight COI1c1itiol1.
(k) Shut down the AVl-9B APU.
Warning: 1. The duration of flight with one engine operative at
power above continuous one should not exceed 6
minutes.
2.The time run by the main gearbox driven by one en-
gine should not exceed 10% of the main gearbox
overhaul period (5% for each engine).
3,lf in training flight the oil temperature of the shutdown
engine drops below +30°C, warm up the engine after
start until the oil temperature rises up to +30°C and
thereafter set the throttle lever to the midway position
and latch.
4.12.2. Landing with One Engine Inoperative for Training Purposes
(1) Execute training landing with one engine inoperative so as the helicopter
