all the consumers, except for the power plant instruments. Turn the throt-
tle control twist grip to the leftmost position, run the engines at idle for 1
to 2 minutes in summer or 2 to 3 minutes in \A!!nter for the purpose of
cooling.
(2) After cooling give to the Flight Engineer an order to shut down the en-
gines. Before engine shutdown set the control stick approximately 1/3
fully travel back.
(3) Upon the Captain's order the Flight Engineer shuts down the engines
proceeding as instructed in para. 3.9.
After the engine rotors come to a complete standstill de-energise all the
consumers remaining on and switch off the storage batteries.
(4) In the course of flying outside of the base aerodrome or flights with stop-
overs at other aerodromes the Flight Engineer should timely change and
submit for processing the 6YP-1)f( flight data recorder tapes and use
them for assessment of the helicopter and its systems status together
with the Captain.
4.15. Search and rescue operations
(1) Before departure for search proceed as follows below:
(a) Switch on the VHF ADF (PA):\VlOKOMOAC YKB) circuit breaker on
the overhead electric power system panel.
(b) On the VHF ADF (APK-Y,Q) control panel, set the mode selector
switch to "NS", the frequency selector switch to VHF (YKB) and the
CHANNELS (KAHAJlbl) selector switch to 4.
(c) On the intercom control box, set the selector switch to PK2 and the
INT - RADIO (COY-PA):\VlO) selector switch to RADIO (PA):\VlO),
with the interphone control box volume control at the maximum vol-
ume position.
(d) Fly the helicopter to enter the search area, and bear in mind that
the VHF ADF (APK-Y):\) detection and homing ranges increase with
altitude (at a height of 500 m the coverage is not less than 25 km).
Set the selector switch MF ADF - VHF ADF to VHF ADF position
(forhelicopters whic:: h (lrenotElquipped with 6CYn indicator)
(e) With the ADF operating in the standby reception mode detection of
a beacon (station) signal should cause coming on of an appropriate
indicating light.
(2) After detection and identification of the beacon (radio station) determine
its location proceeding as follows:
(a) Set the mode selector switch to a position corresponding to the
illuminating light: narrow band NB (YO) or broad band BB (WO).
If the NB indicating light illuminates set the mode selectorswitch to nNB".
(b) Operate the ANT L (AHT. Jl) or R (0) buttons to hloVe the lridicato]'
pointer to the left or to the right of the bearing, and make sure that
pointer returns to the initial position with the button released.
(c) Turn the helicopter so as the heading indicator pointer sets to "0",
fly the helicopter keeping the pointer in this position. At great dis-
tances from the beacon (radio station) begin homing in the narrow
band NB (YO) mode, and as the signal volume heard In the head-
phones increase select the broad band BB (WO) mode since the re-
liability of the VHF ADF (APK-Y):\) operation in this mode in higher.
