In normal pressurization operations, the aircraft can cruise at 41,000 feet and can have a cabin altitude of:

7,300 plus or minus 200 ft.

8,100 plus or minus 150 ft.

6,700 plus or minus 130 ft.

7,800 plus or minus 200 ft.

Correct! Wrong!

If total DC power is lost, automatic pressurization without pilot input is controlled by:

The CABIN DUMP switch.

The COCKPIT TEMP knob.

Maximum delta-P and maximum cabin altitude limit valves.

The pressurization controller.

Correct! Wrong!

The pressurization controller has two modes of operation:

Normal and high altitude.

Normal and Alternate.

Normal and Abnormal.

Normal AC and Abnormal DC.

Correct! Wrong!

On the ground with the throttles below _____ throttle lever angle(TLA), the outflow valves are fully opened allowing all bleed air from the engines to escape overboard into the tail cone.

60%.

85%.

50%.

25%

Correct! Wrong!

This ensures that cabin doors open easily and when opened prevents sudden pressure changes.

The maximum altitude limit valves are only effective as long as:

There is bleed inflow into the pressure vessel.

AC power is available.

The digital auto controller is functioning.

DC power is available.

Correct! Wrong!

During climb, the automatic mode limits the cabin pressurization rate from exceeding approximately _____ regardless of the aircraft climb rate.

500 fpm.

700 fpm.

300 fpm.

600 fpm.

Correct! Wrong!

To pressurize the aircraft and operate normally, the AIR SOURCE SELECT knob must be positioned to:

STANDBY.

DUMP.

L, R, or BOTH.

FRESH AIR.

Correct! Wrong!

The maximum cabin altitude limit valves (one in each outflow valve) automatically prevent cabin pressure altitude from exceeding:

14,000 ft.

14,300 ft plus or minus 300 ft.

10,000 ft plus or minus 300 ft.

10,000 ft.

Correct! Wrong!

The two outflow valves on the aft pressure bulkhead meter open or close to regulate the volume of bleed air outflow into the aircraft tail cone.

True.

False.

Correct! Wrong!

The balance between inflow and outflow establishes cabin pressure.

The CABIN DUMP switch requires DC power. However, it works with the BATT switch in the EMER position.

False.

True.

Correct! Wrong!

The max deferential pressure is:

7.5 + 0.1 psid.

8.5 + 0.1 psid.

8.7 + 0.1 psid.

8.0 + 0.1 psid.

Correct! Wrong!

If both generators fail and the BATT switch is placed in the EMER position, the pilot control of the pressurization system is with the use of the:

Flow control valves.

Pressure regulating shutoff valves (PRSOVs).

CABIN DUMP switch.

AIR SOURCE SELECT knob.

Correct! Wrong!

During descent, as the aircraft descends 500 feet below cruise altitude, the cabin begins to rate down toward DEST ELV. The cabin should reach DEST ELV when the aircraft is _____ above landing field elevation and maintain this altitude until landing.

1,500 ft.

1,000 ft.

2,500 ft.

Correct! Wrong!

If the CABIN DUMP switch is pressed while the aircraft is at 30,000 feet, and there is bleed air being supplied to the pressure vessel, the cabin altitude will climb or descend to what altitude?

30,000 ft because the outflow valves are fully opened.

Stays below 15,000 ft because the pneumatic maximum cabin altitude limit valve overrides the CABIN DUMP.

Remains at 8,000-foot cabin altitude because full cabin pressure dumping does not occur at that altitude.

Sea level if the dump switch is held in position.

Correct! Wrong!

Placing the PRESS CONT switch in the STANDBY position causes the pressurization controller to:

Deenergizes, failing the climb and dive solenoid closed.

Deenergizes, failing the climb and dive solenoid open.

Deenergizes and unpressurizes the pressure vessel.

Switch to high altitude mode when the destination field is above 8,000 feet.

Correct! Wrong!

With a destination field elevation below 8,000 feet, the red 'CABIN ALT' CAS message displays when the cabin altitude exceeds:

12,000 feet.

14,000 feet.

10,000 feet.

8,500 feet.

Correct! Wrong!

With the PRESS CONT switch in the STANDBY position, the CAS displays:

An amber 'WOW MISCOMPARE' CAS message.

A white 'FDR FAIL' CAS message.

An amber 'PRESS CTRL' CAS message.

An amber 'ENG CTRL R' CAS message.

Correct! Wrong!

This message indicates failure of the pressurization controller or that the pilot has selected the PRESS CONT switch to STANDBY, disabling the pressurization controller.

The pressurization system operates in high altitude mode if:

There is a destination field above 8,000 feet set and the aircraft has descended below 24,500 feet.

There is a destination field above 5,000 feet set and the aircraft has descended below 24,500 feet.

There is a destination field above 10,000 feet set and the aircraft has descended below 24,500 feet.

There is a destination field above 12,000 feet set and the aircraft has descended below 25,000 feet.

Correct! Wrong!
