OXYGEN MENU Normal operation 7/37 Observe that the OXY indication has turned green indicating that the oxygen is available. Also check that the high pressure indication (pressure in the bottle before it is regulated) is also displayed in green. OXYGEN MENU Normal operation 8/37 An amber half-frame can appear below the pressure value, meaning that the oxygen pressure is below 1500 PSI. In this case, you should look at your “MIN FLT CREW OXY CHART” to check if the oxygen quantity is sufficient for the flight. OXYGEN MENU Normal operation 9/37 If the amber REGUL LO PR message is displayed, the oxygen pressure from the regulator is low, and you must call maintenance. OXYGEN MENU Normal operation 10/37 In order to test the oxygen mask, check that : • the loudspeakers located on the glareshield are set to ON, OXYGEN MENU Normal operation 11/37 In order to test the oxygen mask, check that : • the loudspeakers located on the glareshield are set to ON, • on the Audio Control Panel, the INT reception knob is selected and adjusted, and the INT/RAD switch is set to the INT position. OXYGEN MENU Normal operation 12/37 You can test the cockpit oxygen mask without removing it from its storage box. Test the flow of oxygen by pressing the TEST AND RESET control.

OXYGEN MENU Normal operation 22/37 The yellow flow indicator shows us that oxygen is flowing continuously and remains on as long as the EMERGENCY pressure selector is pressed. OXYGEN MENU Normal operation 23/37 You can hear the oxygen flow through the loudspeakers. OXYGEN MENU Normal operation 24/37 The final check of the mask is to verify that the supply selector is on the 100% oxygen position. To do this, make sure the selector is in the down position. OXYGEN MENU Normal operation 25/37 Suppose you are now in flight and a cabin depressurization happens. In order to retrieve your oxygen mask from its container, you must squeeze the red grips.

OXYGEN MENU Normal operation 34/37 Notice that : • the OXY ON flag has disappeared, • the oxygen microphone is de-energized, • and the oxygen flow is stopped. OXYGEN MENU Normal operation 35/37 Let’s now go to the cabin. When the MASK MAN ON guarded pb located on the OXYGEN panel is in the AUTO position, the passenger oxygen masks automatically deploy if the cabin altitude exceeds 14,000 feet. Note : The MASK MAN ON pb can also be used to deploy the passenger oxygen masks manually. CCaabbiinn aallttiittuuddee >> 1144 000000 ffeeeett OXYGEN MENU Normal operation 36/37 The PASSENGER SYS ON light illuminates white on the OXYGEN panel, indicating that the masks are deployed. OXYGEN MENU Normal operation 37/37 Oxygen generation starts when the mask is pulled down towards the passenger seat. There are approximately 13 minutes of oxygen available.
