2. Oxygen Panel (Oxygen) [E] Flashcards
What happens when a pilot pushes the CREW SUPPLY PUSHBUTTON?
Valve opens to supply low pressure oxygen to the masks
How does the passenger fixed oxygen system work and how long does it last?
Chemical oxygen generators last for approximately 15 minutes
What does the illumination of the SYS ON light mean? Does this mean that all the masks have deployed?
The signal has been sent to release the oxygen mask doors, but some masks may have to be deployed manually.
What causes automatic deployment of the masks?
Cabin altitude reaching approximately 14,000 feet
How is the crew oxygen mask microphone deactivated when the mask is stowed?
The RESET control slide will accomplish this – it does not happen automatically.
What indication would a pilot have of a crew oxygen cylinder thermal discharge?
The green disk on the lower left side of the forward fuselage would be missing.
Could the passenger oxygen mask provide oxygen for anything other than depressurization?
No, unless there is a written COM procedure for its use.
On the ground, if there is an amber half frame around the CKPT OXY PSI box, where would you look to see if you have enough oxygen for the flight?
