A control panel located in the cockpit overhead panel at the disposal of the pilot
includes :
-
a two-position valve ON/OFF (OXYGEN switch) to permit the supply of the front
seats occupiers masks,
-
a two-position valve DEPLOY/STBY (PASSENGER OXYGEN switch) with
guard to permit the supply of the passengers four masks, when the first valve is
open.
Oxygen pressure is displayed on the MFD.
An altimetric valve provides an automatic passengers masks actuation function at a
cabin altitude between 13000 and 14000 ft when OXYGEN switch is set to ON.
Two pressure-demand type masks allowing quick donning with only one hand,
covering the nose and the mouth, as well as two pairs of smoke goggles are at
disposal of the pilot and of the R.H. front seat occupier. Masks are installed in cups on
the cabin walls aft of the front seats. Permanently connected to the oxygen system,
they are equipped with a micro controlled by the MICRO/MASK switch under cover
located on the instrument panel near the pilot's control wheel. The cockpit masks are
equipped with a microphone, a three-position selector NORMAL, 100 % and
EMERGENCY and with a push-button PRESS TO TEST. The proper flow is signaled
by a flow indicator (blinker) into the oxygen tubing.
The airplane is equipped with two smoke goggles.
Four passengers constant-flow type masks, covering the nose and the mouth and
permanently connected, are installed in two containers on the cabin ceiling. The
opening of these containers and the descent of the masks are controlled by the pilot,
when OXYGEN switch is set to ON and PASSENGERS OXYGEN switch is set to
DEPLOY, or automatically at a cabin altitude between 13000 and 14000 ft with the
OXYGEN switch set to ON. The oxygen flow is obtained by pulling on the mask
bounded by a lanyard cord to a pin. A proper flow is signaled by the filling of the green
bag located on each passenger mask.
