MI1-17-1B. Flight manual
(e) To bail out through the emergency exit kneel on one knee, hold the
exit opening side edges with both hands and push yourself by the
hands and legs to abandon the helicopter with the head down.
(13) If after pulling out the blister (door, cover) emergency release handle it
fails to be released push vigorously the blister (door, cover) outside with a
leg or hand.
(14) In flight with the use of the KKO-nC oxygen equipment, before abandon-
ing the helicopter make sure (after raising from the seat) the oxygen line
is disconnected. If otherwise, disconnect it manually by pulling the red
ball at the P-58 connector.
6.27. Emergency evacuation on the. ground
(1) Emergency evacuation of the occupants from the helicopter on the
ground should be performed in the following way:
(a) The crew members leave the helicopter through the openings of the
released blisters and cargo compartment entrance door.
(b) The passengers leave the helicopter through the openings of the re-
leased entrance doors and emergencyexits of the cargo compartment.
(2) Before emergency evacuation unfasten the safety harness and get out
through the nearest unobstructed emergency exits.
After evacuation from the helicopter run to a safe distance, and aid per-
sons injured.
6.28. Loss of radio communication
(1) The radio communication with the flying control service is considered lost
if, with all the frequency channels used, the flying control officer does not
answer multiple requests during 5 min.
(2) If the radio communication is lost, switch on the "Distress" call transmis-
sion and proceed in accordance with the Flight Operational Rules.
6.29. Failure of tail rotor pitch limit system
(1) Indications
(a) The null indicator movable index does not change its position or de-
flects to the right (to limit the right pedal travel) with the altitude or
outside air temperature increasing.
(b) Illumination of the OFF (OTKn) red switch-light and deflection of the
movable index to the leftmost position.
(2) Crew's actions
(a) Upon occurrence of the first indication of tail rotor pitch limit system
failure in flight set the PITCH LIM SYS (nO,QBlil>K. ynOPbl) switch
to the lower position and make sure the movable index sets to the
leftmost position. In this case, as \Nell as upon occurrence of the
next failure indication execute normal landing avoiding sharp and
large travels of the pedals in order to prevent overloading of the
helicopter transmission.
(b) If the movable index fails to set to the leftmost position with the
PITCH LIM SYS (nO,QBlil>K. ynOPbl) switch set in the lower posi-
tion, execute running landing. If it proves to be impossible, drop the
external stores, use fuel contained in the main fuel tanks and exe-
cute vertical landing with the helicopter headed into the wind.
