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

STANDBY.

L or R MIC switches-MASK.

EMER.

NORM.

Correct! Wrong!

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

NORM.

100% oxygen.

STANDBY.

EMER.

Correct! Wrong!

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

The oxygen bottle has discharged itself due to overpressure.

The halon bottle has thermally discharged itself.

The hydrogen bottle has thermally discharged itself.

The nitrogen blowdown bottle has thermally discharged itself.

Correct! Wrong!

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

30,000 ft.

35,000 ft.

25,000 ft.

20,000 ft.

Correct! Wrong!

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

True.

False.

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.

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

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

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

0 deg.C (32 deg.F).

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

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-PUSH IN.

OXYGEN SUPPLY knob-PULL OUT.

Correct! Wrong!

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

OXYGEN SUPPLY VALVE-PULL OUT.

Oxygen masks-DON and 100% OXYGEN.

OXYGEN SUPPLY VALVE-Reversionary Mode.

OXYGEN SUPPLY VALVE-CREW ONLY.

Correct! Wrong!

The crew oxygen masks are certified up to:

25,000 feet cabin altitude.

40,000 feet cabin altitude.

30,000 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.

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!

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

Terminated as cabin altitude descends through 14,800 feet.

Terminated as cabin altitude descends through 11,500 feet.

Set to the NORMAL mode.

Established.

Correct! Wrong!

Passenger masks are dropped when:

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

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 OXYGEN selector is in DROP MASK, regardless of altitude.

Correct! Wrong!

The cockpit oxygen pressure gauge reads:

Bottle pressure.

Electrically derived system high pressure.

Electrically derived system low pressure.

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

Correct! Wrong!

With a total DC power failure, oxygen is:

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

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

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.

Correct! Wrong!
