A330 ATA 38 -WATER & WASTE

How is the potable water system pressurized?. By the bleed air system. By a ground air pressure connection. By a dedicated compressor. All of the above.

What role does the Vacuum System Controller (VSC) play in the potable water system?. Manages the potable water system. Controls the bleed air system. Pressurizes the water system. Monitors water heaters.

Where is the water quantity in the tanks indicated?. On the Engine Display. On the Flight Attendant Panel (FAP) and PWSP. On the Central Maintenance Computer (CMC). On the Cabin Intercommunication Data System (CIDS).

How is waste transported to the waste tanks in the vacuum toilet system?. By gravitational force. By differential pressure. By manual pumping. By hydraulic pressure.

What role does the Vacuum System Controller (VSC) play in the vacuum toilet system?. Generates necessary vacuum. Controls and monitors the toilet system. Sequences each toilet operation. Indicates waste level on FAP.

How is the waste level in the tanks indicated?. On the Central Maintenance Computer (CMC). On the Flight Attendant Panel (FAP). On the Engine Display. On the Cabin Intercommunication Data System (CIDS).

What does the Flush Control Unit (FCU) do?. Indicates waste level. Sequences each toilet operation. Monitors the vacuum system. Controls the potable water supply.

How is the potable water supplied to the toilet bowls?. From a separate water tank. From the waste tanks. From the potable water system. Directly from ground supply.

When is a vacuum generator used in the toilet system?. When differential pressure is insufficient. During takeoff and landing. When the aircraft is on the ground. During maintenance operations.

How can the A/C Potable Water System be serviced?. Only with electrical power. With or without electrical power. Only by the flight crew. Only on the ground.

To which system is the overflow and venting port of the tanks connected?. The hydraulic system. The bleed air system. The pressurization system. The air conditioning system.

How many potable water tanks are installed in the aircraft?. One. Two. Three. Four.

Where is the potable water stored?. In the galley. In water tanks. In the lavatories. In the cockpit.

What is the role of the Vacuum System Controller (VSC) in the potable water system?. To heat the water. To control and monitor the system. To filter the water. To add chemicals.

Where are the potable water tanks located?. In the cockpit. In the aft cargo compartment. In the wings. In the forward cargo compartment.

Where do the lavatory and galley distribution lines run?. Above the passenger compartment floor. Below the passenger compartment floor. Inside the cockpit. Alongside the fuselage.

How are the lavatory and galley distribution lines protected?. Only shrouded. Only insulated. Shrouded and insulated, or insulated and heated. Unprotected.

What is the function of manual water Shut-Off Valves (SOVs)?. To increase water pressure. To heat the water. To isolate a lavatory or a galley. To monitor water temperature.

Where is the water quantity information displayed?. On the cockpit display. On the passenger screens. On the FAP and PWSP. Only on the FAP.

What happens when the pre-selected water quantity is reached during filling?. The water heater activates. The fill/drain valve automatically closes. The pressure drops. The system shuts down.

How is the toilet waste system divided?. By compartments. By altitudes. By left and right sides. By deck levels.

What initiates the flush sequence in the lavatory?. Pulling a lever. Pushing the flush switch. Activating the water pump. Opening the toilet lid.

What happens if a failure occurs in the flush system?. Nothing. An alarm sounds. The system shuts down. A signal is transmitted to the VSC.

What creates the necessary differential pressure for waste movement on the ground?. Cabin pressure. Engine pressure. Vacuum generators. Manual pump.

What action does the VSC take if the vacuum generator overheats?. It increases speed. It shuts down the generator. It increases pressure. It de-energizes the generator.

What tests does the VSC BITE perform?. Power-up and continuous monitoring tests. Heating and cooling tests. Pressure and vacuum tests. Cleaning and flushing tests.

What happens when you push the reset pushbutton switch?. The system shuts down. The VSC does a power-up test. The water heater activates. The flush valve opens.
