After starting the engines and disconnection of the external electrical
power source switch off the white dome lights, set the DAY - NIGHT
(,[IEHb - H04b) selector switch to NIGHT (H04b) and switch on the
FLASH (MlllrAnKA), ANTI-COll LIGHT (np06nECK) and BLADE TIP
(KOHTYP.OrHIII) switches.
Set the navigation and formation lights switches to BRIGHT (HPKO) or
DIM (TYCKnO) depending on the assigned mission.
Taxi with the Cl:>P-100 taxi light on. Switch on the Cl:>nn-? landing/search
lights in case of necessity for more thorough observation of forward
space, and before execution of turns. The Cl:>nn-? landing/search lights
operational duty is 5 minutes on,
5
minutes off.
(3) Take off with both the Cl:>P-100 taxi and Cl:>nn-? landing/search lights on.
Adjust the direction of the lights beams in hovering at a height of 3 to 5 m
by operating the respective selector switches Installed at the collective
pitch control lever. Procedure of takeoff by night does not practically differ
from that by day, but at the moment of lift-off pay attention to lateral
shifts, and maintain direction by referring to the runway lights and the
helicopter landing and taxi lights.
(4) Execute acceleration and climbout to a height of 50 m more gradually
than by day. At a height of 30 to 50m completely select to instrument fly-
ing and switch off the landing and taxi lights. Maintain the same climb,
horizontal flight and gliding speeds as during day flying, Execute turns
with banks not more than 15°.
(5) During night flights pilot the helicopter by referring mainly to the instru-
ments and periodically observe the air space.
Inadvertent ingress into clouds is displayed by appearance of a naviga-
tion lights reflection and disappearance of ground reference objects.
Warning: In case of inadvertent entering an icing area (this event being
displayed by illumination of the "ICING" (06nE,[IEH) annun-
ciator or detection of ice on the windshield or the side blisters)
manually switch on the main and tail rotor anti-icing system,
windshield and pitot tubes heaters, report to the flying control
officer, and take measures to leave the icing area.
The Pilot-Navigator should follow the instructions of para. 4.18, (13) in
night flying.

Execute approach and landing manoeuvres following the same proce-
dure as by day. At a height of 50 to ?Om switch on the Cl:>P-100 taxi and
Cl:>nn-? landing/search lights. If these lights cause appearance of light
screen reducing observation of the ground, switch off the lights and find
out the landing area oil the grouild illumiilated by the stationary landiilg
lights or referring to other lighted objects. In execution of landing assess
the true height by reading the radio altimeter and check it by observation of
illuminated ground areas and reference objects. If the ground surface is in-
adequately illuminated by the Cl:>nn-? lights or they fail, switch on and ex-
tend the npCl:>-4 lights. Execute landing with the npCl:>-4 lights on (the opera-
tional duty of the npCl:>-4 lights is 5 minutes on, 5 minutes off).
(?) After touchdown reduce the main rotor pitch very slowly and only being
completely sure the helicopter stands firmly on the ground. Taxi to the
