What are the three independent supplemental oxygen systems that are installed?
1. Cockpit crew oxygen
2. Cabin passenger & flight attendant oxygen system
3. Portable cabin oxygen system
The Crew Oxygen system supplies oxygen to how many quick donning masks?
3 (4 if installed for ACM)
Where is the high pressure oxygen cylinder located?
What color is the oxygen blow out disk that is inspected during the external pre-flight inspection and where is it located?
Green; left forward fuselage
What does the absence of the oxygen blow out disk indicate?
The crew oxygen has been depleted due to thermal expansion.
Do the crew masks have to be removed from the storage box to perform a preflight test of the air flow and communication capabilities?
Can the crew oxygen masks be set to provide a positive mask pressure?
Yes, by rotating the emergency selector on the front of the mask one third of a turn to the EMERGENCY position.
In the Normal position, when does the crew oxygen mask provide 100% oxygen supply?
Above 35,000 feet.
Note: AAY procedure is to leave the selector in 100% setting at all times.
When is the crew oxygen pressure on the ECAM DOOR/OXY page displayed as a green value with an amber half frame?
below 1500 psi
When is the crew oxygen pressure on the ECAM DOOR/OXY page displayed as an amber value with an amber half frame?
below 400 psi
When is the crew oxygen pressure displayed as "OXY 0 PSI" in amber?
Typically when the OXYGEN CREW SUPPY pb is OFF. If the push button is on, there is insufficient or no oxygen bottle pressure.
What will appear on the DOOR/OXY ECAM page if the regulated oxygen pressure drops below 50 psi?
amber REGUL LO PR indication
Will the crew oxygen mask microphone automatically be deactivated when the mask is stowed?
No, you must press the RESET switch
On each crew oxygen mask storage box, what indicates that oxygen is flowing to the mask?
yellow cross (blinker)
What method is used to supply passenger cabin supplemental oxygen?
At what cabin altitude should the cabin oxygen mask compartment doors be automatically opened?
Can the cabin oxygen mask compartment doors be manually commanded to open?
Yes, by pushing the MAN ON pb, located on the oxygen panel in the flight deck.
What is illuminated when the cabin oxygen mask compartment doors have been automatically or manually commanded open?
SYS ON light is illuminated
Does the SYS ON light mean all passenger oxygen masks have deployed?
No. It only means the compartment doors have been commanded open.
Is there a manual method to open a cabin oxygen mask compartment door that failed to open when automatically or manually commanded?
Yes, by using a Manual Release Tool (MRT) typically made available to the flight attendants.
How are the cabin oxygen generators activated?
They are manually activated by forcefully tugging on any one of the connected oxygen mask hoses.
Once the cabin oxygen generator is activated, will oxygen flow to each associated mask?
Does the cabin oxygen system provide oxygen and smoke protection?
No. Oxygen only
Is the cabin oxygen system is a continuous flow or on demand system?
How long can each oxygen generator provide oxygen to the associated cabin masks?
minimum of 15 minutes
How many portable oxygen bottles are available for first aid or as walk-around units?
How long will the portable oxygen bottles supply oxygen?
approximately 65 minutes
