The pack controller detects an overheat in air conditioning pack 2. What should happen next in response to this fault?. The appropriate Pack Flow Control Valve will close and FAULT will illuminate amber on the pack 2 pushbutton. The Pack Flow Control Valve will close and FAULT will illuminate amber on the HOT AIR pushbutton. The hot air valve will close and FAULT will illuminate on the HOT AIR pushbutton.

Which of the following occurs when the RAM AIR PB is pressed? Select all that apply. RAM AIR ON is displayed in green on the CAM memo. Outflow valve automatically opens when the cabin differential pressure is less than 1 PSI (If the cabin MODE SEL PB is AUTO). The inlet and extraction valves will automatically close. The emergency ram air inlet will open. "ON" will illuminate in white on the PB.

Which pack controller fault conditions would result from both primary and secondary channel failure?. Air conditioning capability will be degraded. The pack outlet temperature is stabilized between 41 degrees Fahrenheit and 86 degrees Fahrenheit in a maximum of 6 minutes. Secondary channel will act as a backup. Temperature regulation will not be affected.

If a zone controller (older A320) experiences a failure of the primary channel, what impact will this have on the air conditioning capability?. PACK 1 delivers 68° F, PACK 2 delivers 50° F. No impact. Hot Air Valves close, Trim Air Valves close, Temperature regulated to 76° F in each of the 3 zones.

An amber PACK FAULT light illuminated indicates which of the following? Select all that apply. None of the answer choices are correct. Switch position disagreement with the pack flow control valve. High air pressure. Pack Overheat.

If a Pack Controller experiences failures of both the primary and secondary channels, to what temperature will the corresponding pack outlet temperature be regulated?. 25° C (77 degrees F). 40° C (104 °F). Between 5° C (41° F) and 30° C (86 °F). 10° C (50 degrees F).

Your aircraft is on the ground with the doors closed and the low pressure ground air cart connected. You notice the DITCHING pushbutton is selected ON. What action is appropriate?. None. The automatic controller will correct any abnormal pressure. None. The safety valves will correct any abnormal pressure. Select the DITCHING pushbutton to OFF, allowing the automatic controller to open the outflow valve.

You are flying with the pressurization system in MANUAL mode and are forced to make a water landing and ditching becomes necessary. You select the DITCHING pushbutton ON. What other action is necessary?. None. Selecting the DITCHING pushbutton seals the aircraft below the water line. Use the MAN V/S CTL DN setting to close the safety valves. Use the MAN V/S CTL UP setting to close the outflow valve. Use the MAN V/S CTL UP setting to close the safety valves. Use the MAN V/S CTL DN setting to close the outflow valve.

The maximum normal cabin altitude is ____ feet.

When do the pressure controllers switch roles to become the active one?. After each landing. Only in the event of a failure. Each day. After gear retraction.

The automatic pressurization system is depressurizing the system but is limiting the cabin vertical speed to a maximum of 750 feet per minute. What is the current pressure controller mode?. Cruise. Takeoff. Climb. Descend.

What does the amber FAULT light in the MODE SEL PB for cabin pressure indicate?. Cabin altitude exceeds 14,000 feet. There is no FAULT light associated with this switch. Both automatic pressure controllers are faulty. One cabin pressure is faulty.

Select the scenario that would call for manual operation of the Pressurization System. Failure of the Cabin Pressure Controller 2(CPC2). Dual FMGC Failure. Dual Cabin Pressure Control Failure. Failure of the Cabin Pressure Controller 1(CPC1).

How is the intermediate configuration different from the closed configuration?. Extract fan is off. Small internal flap on the extract valve opens to exhaust some of the heated air overboard. Blower fan draws in outside air through the inlet valve.

What does a FAULT light on the EXTRACT PB indicate?. Low extract pressure. Smoke warning is activated. All of the answer choices are correct. Computer failure.

A duct overheat is detected in the cargo heating system. The cargo heating controller will perform which action?. Close the outlet isolation valve. Close the inlet isolation valve. Close the cargo pressure regulating valve. Close the inlet and outlet isolation valves.

When the BLOWER and EXTRACT PB's are selected to OVRD, what positions are the valves in?. Inlet valve closed. Inlet valve closed; Extract valve open. Inlet valve closed: Extract valve closed. Extract valve closed. Inlet valve open. Inlet valve open; Extract valve closed.

Can conditioned air ever be introduced to the avionics compartment?. Only on the ground. Never. Always while airborne. In the smoke or abnormal configuration.

You look at the overhead ventilation panel and see the panel configuration shown here. You set both faulted pushbuttons to OVRD. What is the resulting configuration of the avionics ventilation system?. Intermediate Configuration. Open Configuration. Smoke configuration.

What does a FAULT light on the BLOWER PB indicate?. Duct overheat. Low blower pressure. All of the answer choices are correct. Computer failure. Smoke warning is activated.

When the BLOWER and EXTRACT PB's are selected to OVRD, which fan is off?. None of the answer choices are correct. Exciter. Blower. All of the answer choices are correct. Extract.
