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.

1,000 ft.

1,500 ft.

2,500 ft.

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!

The pressurization system operates in high altitude mode if:

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.

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 8,000 feet set and the aircraft has descended below 24,500 feet.

Correct! Wrong!

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

DC power is available.

There is bleed inflow into the pressure vessel.

AC power is available.

The digital auto controller is functioning.

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?

Sea level if the dump switch is held in position.

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.

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

Correct! Wrong!

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

8,100 plus or minus 150 ft.

7,300 plus or minus 200 ft.

6,700 plus or minus 130 ft.

7,800 plus or minus 200 ft.

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:

Pressure regulating shutoff valves (PRSOVs).

AIR SOURCE SELECT knob.

Flow control valves.

CABIN DUMP switch.

Correct! Wrong!

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

False.

True.

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.

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

Deenergizes, failing the climb and dive solenoid open.

Deenergizes and unpressurizes the pressure vessel.

Deenergizes, failing the climb and dive solenoid closed.

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

Correct! Wrong!

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

The CABIN DUMP switch.

The pressurization controller.

Maximum delta-P and maximum cabin altitude limit valves.

The COCKPIT TEMP knob.

Correct! Wrong!

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

700 fpm.

600 fpm.

500 fpm.

300 fpm.

Correct! Wrong!

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

An amber 'PRESS CTRL' CAS message.

A white 'FDR FAIL' CAS message.

An amber 'WOW MISCOMPARE' 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.

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

L, R, or BOTH.

STANDBY.

FRESH AIR.

DUMP.

Correct! Wrong!

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

14,300 ft plus or minus 300 ft.

10,000 ft plus or minus 300 ft.

14,000 ft.

10,000 ft.

Correct! Wrong!

The pressurization controller has two modes of operation:

Normal and Alternate.

Normal AC and Abnormal DC.

Normal and high altitude.

Normal and Abnormal.

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.

25%

50%.

60%.

85%.

Correct! Wrong!

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

The max deferential pressure is:

8.0 + 0.1 psid.

7.5 + 0.1 psid.

8.7 + 0.1 psid.

8.5 + 0.1 psid.

Correct! Wrong!
