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 four passenger masks, when the OXYGEN
switch is set to ON.
Oxygen pressure is displayed on the MFD.
An altimetric valve provides an automatic actuation function for passenger masks at a
cabin altitude between 13000 and 14000 ft when the OXYGEN switch is set to ON.
Two pressure-demand type masks that allow quick donning with only one hand to
cover the nose and the mouth are at disposal of the pilot and the front passenger,
along with two pairs of smoke goggles. These masks are installed in cups on the cabin
walls aft of the front seats. For the ease of donning and for ergonomic reasons, the
pilot's mask is located in the right-side cup, and the front passenger mask is located in
the left-side cup. The masks are permanently connected to the oxygen system.
The smoke goggles are stowed in the cabinet drawer behind the right front seat.

a microphone, controlled by the MICRO/MASK switch under cover located on
the instrument panel near the left control wheel.
