3. If DC power fails, placing the OXYGEN CONTROL VALVE knob in:

A. MANUAL DROP deploys the passenger masks, regardless of cabin altitude.
B. MANUAL DROP deploys the passenger masks only if 14,500 feet cabin altitude is exceeded.
C. CREW ONLY does not restrict oxygen to the crew only if the cabin altitude is above 14,500 feet.
D. Any of the three operating positions does not route oxygen to the passengers—they have their own oxygen.

4. The purpose of the altitude pressure switch is to:

A. Bypass oxygen flow directly to the passengers regardless of OXYGEN CONTROL VALVE knob position.
B. Open a solenoid at 14,500 feet cabin altitude, allowing oxygen flow to the passenger oxygen distribution system.
C. Close a solenoid valve at 14,500 feet cabin altitude, stopping oxygen flow to the passengers.
D. Restore cabin altitude to 8,000 feet so that oxygen is not required.

5. If the OXYGEN CONTROL VALVE knob is in the CREW ONLY position:

A. The passenger masks cannot be dropped automatically.
B. The passenger masks do not deploy automatically, but they can still be dropped manually.
C. The passengers still receive oxygen if the cabin altitude is above 8,000 feet.
