ATA 38 WATER WASTE

What are the three subsystems that make up the water and waste system on Airbus A320 Family aircraft?. Potable water system, waste water system, toilet system. Fuel system, electrical system, hydraulic system. Navigation system, communication system, entertainment system.

Where is the potable water tank located in the A318, A319, and A321 aircraft?. In the aft cargo compartment. in the lavatories. In the galleys.

Where is the potable water tank located in the A320 aircraft?. In the forward cargo compartment. In the aft cargo compartment. In the aft bulk cargo.

Which aircraft in the Airbus A320 Family has a different location for the potable water tank compared to the others?. A320. A318. A319.

What controls the potable water service panel heating, especially in winter conditions?. A thermostat. The Flight Attendant Panel (FAP). The vacuum toilet system.

Where are the water and waste indications displayed for the flight attendants?. On the Flight Attendant Panel (FAP). On the aircraft's exterior. On the passenger seats.

How is used water from the lavatory washbasins and galley sinks discarded in the waste water system?. Discharged overboard outside. stored in the cargo compartment. converted into drinking water.

What feature is integrated into the drain masts of the waste water system to prevent ice formation?. Electric heating elements. Vacuum generator. Compressed air.

What type of system does the toilet system on Airbus A320 Family aircraft use for flushing?. Differential pressure toilet system. Potable water system. Electrical system.

What happens when the waste holding tank is full in the toilet system?. The toilet system shuts down. The waste is recycled. The waste is diverted to the potable water tank.

What provides the necessary differential pressure in the waste system to move waste from the toilet bowl to the tank at low altitude or on the ground?. A vacuum generator. the waste holding tank. The cabin air pressure.

Which system controls the flushing system operation and stops it when the waste servicing panel is open?. The Vacuum System Controller Function (VSCF). the waste holding tank. The potable water system.

Where is the waste holding tank located in the aircraft?. Behind the bulk cargo compartment. In the galleys. In the forward cargo compartment.

What components are included in the waste holding tank?. A waste drain valve, two rinse line connections, and a liquid level sensor. A potable water tank, a vacuum system controller, and a heating element. A water separator, a liquid level transmitter, and an ice prevention system.

What can be insulated in the waste holding tank system as an option?. The lines between the tank and the service panel. The potable water tank. The toilet bowl.

why are the lines between the waste holding tank and the service panel insulated and heated. to prevent freezing and ice information. to keep the waste warm. to save energy.

what controls and monitors the system functions and related electric components in the vacuum toilet system. the cabin intercommunication data system (CIDS). the flush control unit (FCU). the waste holding tank.

what happens when the waste holding tank is full in the toilet system. the toilet system shuts down. the waste is automatically ejected. the waste is recycled.

the water and waste indications are displayed automatically as soon as the service panel is open. true. false.

in the flight attendant panel (FAP) the filling quantity cannot be selected as an option. false. true.

there is only one control handle on the water service panel. false. true.

on the A320 the overflow valve opens mechanically when the fill/drain control handle is set to the drain position. true. false.

when does the overflow valve light come on and what does it indicate when the valve is in the open position. the overflow valve light comes on during filling indicating that the valve is open. the overflow valve light comes on during draining indicating that the valve is closed. the overflow valve light comes on when the air compressor is activated.

the fill/drain control handle is initially positioned to drain when filling the water tank. false. true.

the green tank full light comes on when the tank is empty. false. true.

what happens when the toilet service panel door is open on the ground. all the toilet operations are stopped through DEU B. flush signals are inhibited. the vacuum generator starts automatically.

what is the primary purpose of the drain control handle located at the service panel. initiating waste holding tank draining. activating the DEU B. controlling cabin pressurization.

when is the drain control handle used during ground service. to activate the vacuum generator valve. to stop all toilet operations. to initiate cabin pressurization.

what is the purpose of opening the cap of the waste drain connection during the servicing process. to connect the toilet service vehicle drain hose. to check for leaks from the waste drain connection. to flush the waste tank with disinfectant solution.
