4. FLIGHT
4.1. Taxiing
(1) Before taxiing the Flight Engineer should make sure that:
(a) The ground electrical power source cables are disconnected.
(b) The grounding cable is placed in its well.
(c) The airborne ladder is loaded into the helicopter and the cargo
compartment doors are closed.
(d) CP (contingency power) switches (located on the centre console) of
both engines are ON.
(e) The 3l..\H-916 fuel pumps are on as indicated by the setting of the
switches and illumination of the annunciator. Report the Captain:
"Ready for takeoff, fuel pumps on".
(2) Having received the crewmembers reports on readiness for taxiing the
Captain should make sure the APU is shut down, all the circuit breakers
are switched on, readings of all the instruments are
OK
and there are no
obstacles on the taxiing course. This done, proceed as follows below:
(a) Turn the throttle control twist grip to the rightmost position.
(b) Turn on the dust protection device disregarding the degree of
preparation of the field or aerodrome.
(c) Make sure the main rotor speed is 95±2%.
(d) Establish radio link with the airfield controller and receive clearance
for taxiing.
(e) Release the main LG wheel brakes.
(f) Increase the main rotor collective pitch to 1 to 2° and smoothly push
the control stick to establish translational motion of the helicopter.
(3)
It is allowed to taxi on hard and even surface with the engine dust protec-
tion devices on, and avoiding lift off condition. If the surface properties do
not allow taxiing proceed to hops at low height.
(4) The taxiing speed should not exceed 15 to 20 km/h. Control the taxiing
speed to environment and surface properties by application of the LG
wheel brakes, bearing in mind that the brakes are highly effective.
Turn during taxiing by application of the pedals. In so doing, avoid com-
plete unloading of the nose LG shock strut.
(5) Taxi at wind speed not exceeding 15
mis,
at headwind not exceeding
25m/s.
When taxiing in crosswind the helicopter shows a tendency to
weathervane into the wind. Counteract this tendency by appropriate ap-
plication of the pedals and the rolling tendency by application of the con-
trol stick.
(6) If forward Visibility is nil due to severe dust or snow swirl induced by the
main rotor, stop the helicopter.
To stop the helicopter during taxiing set the control stick to a position
close to neutral, apply the wheel brakes. Continue taxiing after making
sure there are no obstacles ahead.
Caution:
1. If ever increasing oscillations of the helicopter arise dur-
ing taxiing immediately reduce the main rotor collective
