CLOG R ENG annunciator comes on, stop testing the affected engine
and shut it down.
(2) Rotate the throttle control twist grip to the right, set the AC generators
and rectifiers switches to ON (BKn.). Call DISCONNECT GROUND
POWER SOURCES. After the ground power sources are disconnected
and the AC and DC power EXT PWR ON (A3P. m1T. BKIlI04EHO) an-
nunciator goes out, set the EXT PWR (A3PO,QP. m1TAH) selector
switches to OFF (BbIKJl).
Check the AC generators output voltage which should be within the limits
of 200 to 205 V, the BV-6A rectifiers output voltage which should be
within the limits of 27 to 29V and the transformer output voltage which
should be 115 VAC.
Set the nO-500 INV 115 VAC (nO-500 - 115) and nT-200 INV 36 VAC
(nT-200 - 36) selector switches to AUTO (ABTOMAT).
(3) Switch on all the flight, navigation, radio communication and electronic
equipment required for the flight, and test the equipment for proper func-
tioning. Before switching on the GYRO (ABliIAfOP1iI3) switch depress
the Af6-3K gyro horizon caging button.
(4) Test the CnVV-52 tail rotor pitch limit system by setting the CnVV-52
switch located on the electric overhead panel LH panel to ON (BKIl), and
assess the system operational status by going out of the OFF (OTKJl) red
switch-light installed on the face panel of the 6Y-32 unit.
Depress the OFF (OTKJl) switch-light and set the "B" switch to "P". This
done, the null indicator pointer should align with the left intermediate mark
on its dial. Switch off switch "B" and release the
switch-liqht, The null indica-
tor pointer should set to the central position. Test the temperature channel
in the similar way for which purpose set switch "B" to "t",
(5) Test the autopilot following the procedure below:
(a) Depress the ON (BKIl.) switch-lights of all the channels on the
autopilot controller. This done, all the SWitch-lightssho.uld cOrne on,
the liIH-4 trim indicator pointers should be centered within the
pointer width with the flight controls in neutral position. Deflect the
control stick to make sure that the pointers K and T of the liIH-4 in-
dicator respond to control inputs (the directions of control stick and
indicator pointers movements should match). Check the autopilot
channels for disengagement upon depression of the AP OFF
(BbIKn. An) button at the control stick, this condition being dis-
played by going out of all the lights.
(b) Gheckthe altitude channel for engagement upon depression pHhe
ALT ON (BKJl. BbICOTA) switch-light. Momentarily depress up the
TEST (KOHTPOIlb) selector switch and observe indicator pointer B
to move upward. Move the collective pitch control lever 1° up from
the lower stop, engage the altitude channel again and momentarily
depress the TEST (KOHTPOIlb) selector switch down. This done,
pointer B should move downward. Check the altitude channel for
disengagement upon depression of the FRICT (Cl>PliIKl..llilOH) but-
ton located on the collective pitch control lever.
(c) Test the autopilot directional channel. With the pedals set neutral
