Kko-Ilc2 Oxygen Equipment - Kazan Helicopters Mi-17-1V Flight Manual

MI1·17-1B. Flight manual
15M oxygen mask for oxygen supply to cases is as instructed in item (1).
(5) The cases are fed with oxygen on the ground and in flight periodically, in
case of necessity (upon the medical attendant's decision).
Use oxygen as follows:
(a) Connect the KM-15n oxygen mask to the Kn-21 oxygen regulator.
(b) Don the mask and make sure it fits against the face.
(c) Open the cutoff valve.
(d) On the ground and in flight at altitudes up to 2000 m to feed oxygen
open the Kn-21 oxygen regulator emergency delivery valve. Open
the Kn-21 oxygen regulator emergency delivery valve as well upon
failure of the oxygen regulator, difficulties in breathing or when feel-
ing sick at any altitude.
7.4. KKO-IlC2 Oxygen Equipment.
Use the oxygen equipment for flight above 4000 m altitude.
(1) The equipment includes 3 sets of quick-removable KKO-IlC2 oxygen
equipment installed on the crew work stations.
Each set includes:
- Kn-75A oxygen regulator;
- Kn-58 oxygen regulator;
- P-58 connector;
- KM·16H oxygen mask with lock.
(2) To prepare and use the oxygen equipment in flight the oxygen regulator
is provided with:
- connection for oxygen bottle;
- oxygen supply connection;
- oxygen supply valve provided with a pressure gage for checking the
oxygen presence;
- handle for opening the additional oxygen supply valve (blue); the handle
has two positions MIXTURE and 100% O
2 . ;
- handle for opening the oxygen continuous supply valve (red); the handle
has ON/OFF positions.
(3) Up to an altitude of 2000
m,
the additional oxygen valve handle being set
to MIXTURE position, the respiration is ensured by ambient air, sucked
through the mask oxygen dilutor valve. At a higher altitude the air-diluted
oxygen will be automatically supplied: the higher is an altitude, the more
oxygen is supplied. The oxygen supply is monitored with a flow indicator
which is integrated into the disconnector hose. The equipment design al-
lows to select the pure oxygen respiration and to turn on a continuous
oxygen supply,
(4) Before flight with use of oxygen equipment it is necessary to inspect and
check the equipment for operation, to do this each crew member should:
- make sure that there are no oil spots on the equipment parts;
- make sure that the additional oxygen handle is set to MIXTURE position
and the continuous oxygen supply handle is to OFF position;
- make sure the disconnector pin is locked (with thread);
