1. The cockpit oxygen pressure gauge reads:

• A. The oxygen pressure which is present at the crew masks
• B. Electrically derived system low pressure
• C. Bottle pressure
• D. Electrically derived system high pressure

2. Passenger masks are dropped when:

• A. The OXYGEN CONTROL VALVE knob is in the NORMAL position and cabin altitude exceeds 14,500 feet
• B. The cabin altitude exceeds 14,500 feet, regardless of OXYGEN knob position
• C. The OXYGEN CONTROL VALVE knob is in the MANUAL DROP position, regardless of altitude
• D. Both A and C

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.
• D. Normal DC power is removed from the passenger mask door actuators, thus pre- venting them from dropping the masks.

6. If normal DC power is lost with the OXYGEN CONTROL VALVE knob in the NORMAL position:

• A. The passenger masks deploy immediately, regardless of the cabin altitude.
• B. The passenger masks cannot be dropped manually.
• C. The oxygen pressure gauge on the copilot panel is inoperative.
• D. Automatic dropping of the passenger masks does not occur.

1. The standby HSI receives its heading data from:

• A. AHRS 1
• B. AHRS 2
• C. AHRS 3
• D. A self-contained directional gyro

2. In order to fully function, the autopilot and yaw damper both require:

• A. One valid AHRS
• B. Two valid AHRS without attitude miscompares
• C. Three AHRS
• D. No AHRS

3. Your PFD shows red flags of IAS, ALT, and VS. Which reversion control should you use?

• A. AHRS REV
• B. DADC REV
• C. Display REV TO MFD
• D. Display REV TO PFD

4. Without normal aircraft DC power, the standby fight display battery should last:

• A. 10 minutes
• B. 30 minutes
• C. 60 minutes
• D. 88 minutes
