Normal = air/oxygen mixture on demand at a ration based on cabin altitude

25
Q

Emergency position of Oxy mask does what? Caution?

A

Supplies 100% oxygen under positive pressure at all altitudes (to protect against smoke and harmful vapours)
Caution as it depletes oxygen at a higher rate than normal mode and only use as required (comms may be harder too)

26
Q

Smoke vent valve selector does what on mask?

A

Opens the vent valve allowing oxygen to flow to the smoke goggles

A

Automatically switched to the Standby AC Bus

28
Q

When does the Indicator Light brightness get automatically overridden from DIM? (3)

A
  1. Ambient flight deck light level increases to a preset crossover level
  2. Loss of equipment cooling air flow as detected in the flight deck or in the FWD E/E bay
  3. Equipment cooling air overheat is detected in the flight deck or in the FWD E/E compartment or at the cooling air supply source
29
Q

Four times when seat belt signs come on when switch is in AUTO?

A
  1. landing gear not up and locked, or
  2. Flap lever not up, or

35
Q

How is passenger oxygen generated?
