Passenger masks are dropped when:

When cabin altitude exceeds 10,500 feet.

The OXYGEN CONTROL VALVE is in NORMAL, normal DC power available, and cabin altitude exceeds 14,800 feet.

The cabin altitude exceeds 13,500 feet, regardless of OXYGEN selector position.

The OXYGEN selector is in DROP MASK, regardless of altitude.

Correct! Wrong!

On descent, oxygen flow to the passenger masks is automatically:

Terminated as cabin altitude descends through 14,800 feet.

Set to the NORMAL mode.

Terminated as cabin altitude descends through 11,500 feet.

Established.

Correct! Wrong!

With the amber CAS message OXYGEN OFF displayed, required pilot action is to:

Push the TMR/REF soft key.

Rotary TEST knob-To ANNU.

OXYGEN SUPPLY knob-PULL OUT.

OXYGEN SUPPLY knob-PUSH IN.

Correct! Wrong!

Pilot action required with a red CABIN ALT message displayed is to:

OXYGEN SUPPLY VALVE-Reversionary Mode.

OXYGEN SUPPLY VALVE-PULL OUT.

Oxygen masks-DON and 100% OXYGEN.

OXYGEN SUPPLY VALVE-CREW ONLY.

Correct! Wrong!

The cockpit oxygen pressure gauge reads:

Electrically derived system low pressure.

Electrically derived system high pressure.

Bottle pressure.

The oxygen pressure, which is present at the crew masks.

Correct! Wrong!

The flight crew oxygen masks need to be removed from the airplane if the temperature is forecast to be below:

0 deg.C (32 deg.F).

-20 deg.C (-4 deg.F).

+10 deg.C (50 deg.F).

-10 deg.C (14 deg.F).

Correct! Wrong!

On crew masks, 100% oxygen shall be selected above 20,000 feet cabin altitude. At cabin altitudes of 20,000 feet and below, normal (N) is to be selected.

True.

False.

Correct! Wrong!

With a total DC power failure, oxygen is:

Available to passengers via the OXYGEN CONTROL VALVE in the CREW ONLY position.

Available to passengers via the OXYGEN CONTROL VALVE in the DROP MASK position.

Available to passengers via the OXYGEN CONTROL VALVE in the NORMAL mode.

Available to occupants regardless of the position of the OXYGEN CONTROL VALVE.

Correct! Wrong!

A green overboard discharge indicator (disc) is on the right side of the nose section directly below the nose access door.

False.

True.

Correct! Wrong!

If the disc is ruptured, the oxygen bottle has experienced overpressure and is now empty. If the disc ruptures, the flight crew shall perform maintenance before flight.

Prolonged use of passenger oxygen masks above _____ cabin altitude is not allowed:

25,000 ft.

30,000 ft.

20,000 ft.

35,000 ft.

Correct! Wrong!

During the walkaround, the flight crew notices the green overboard discharge indicator is missing, this indicates:

The nitrogen blowdown bottle has thermally discharged itself.

The halon bottle has thermally discharged itself.

The hydrogen bottle has thermally discharged itself.

The oxygen bottle has discharged itself due to overpressure.

Correct! Wrong!

When using the oxygen mask for smoke protection, the mask regulator should be set for:

STANDBY.

NORM.

EMER.

100% oxygen.

Correct! Wrong!

After donning the oxygen mask, the mask microphone should be set for:

STANDBY.

NORM.

L or R MIC switches-MASK.

EMER.

Correct! Wrong!

The crew oxygen masks are certified up to:

30,000 feet cabin altitude.

40,000 feet cabin altitude.

25,000 feet cabin altitude.

35,000 feet cabin altitude.

Correct! Wrong!

Oxygen masks are certified to 40,000 feet cabin altitude for the crew only. The CREW ONLY mode operates with or without DC power.
