MIl-17-1B. Flight manual
Note: If airspeed was below 120 km/h at the moment of en-
gine failure and the helicopter failed to attain a speed
adequate for horizontal flight with one engine running at
contingency power in acceleration up to a height of 20
to 10m, proceed to vigorous slowing down of the verti-
cal and forward speeds and execute landing following
the instructions of Para. (2).
(3) Crew's actions upon failure of one engine at a height below 100 m:
(a) Reduce the main rotor collective pitch to a value required for main-
taining the main rotor speed at a level of not less than 92 %.
(b) Simultaneously and appropriately apply the control stick and pedals
to counteract rolling and turning.
(c) Read the engines instruments to recognize the failed engine. Make
sure that CP (contingency power) switch of the operating engine is
set to ON.
(d) Proceed to deceleration of the helicopter in climb by pitching up to
10 to 15 deg if the airspeed was above 120 km/h.
(e) Move the separate throttle control lever of the failed engine fully
downward.
(f) Give an order to the Flight Engineer to close the HP fuel shutoff and
fuel fire shutoff valves of the failed engine.
(g) Upon attainment of an airspeed of 120 km/h establish horizontal
flight condition.
(h) Operate the collective pitch control lever to set such a power to the
operating engine at which the helicopter flies without loss of alti-
tude.
(i) Make sure the engine operates normally and the helicopter is capa-
ble of performing horizontal flight.
Ul
Continue flying to the destination aerodrome at this speed or select
an area and land the helicopter proceeding as instructed in Para. (2).
1) If the airspeed is less than 80 km/h at the moment of engine
failure proceed as follows below:
(a) Reduce the main rotor collective pitch to
a
value re-
quired for maintaining the main rotor speed at a level of
not less than 92 %.
(b) Simultaneously and appropriately apply the control stick
and pedals to counteract rolling and turning.
(c) Make sure that CP (contingency power) switch of the
operating engine is set to ON.
(d) Accelerate or decelerate the helicopter to establish an
airspeed of 40 to 60 km/h depending on the helicopter
gross weight.
(e) Establish descent at a vertical speed not exceeding 3 to
4 m/s.
(f)
Descend to a selected area. Execute landing as in-
structed in Para. (2).
(4) Crew's actions upon an engine failure in hovering:
(a) At a hovering height up to
3
m:
1) When the helicopter begins to descend mmedlately pull up
the collective pitch control lever to reduce the vertical speed
