water and waste system
Potable water is stored in a tank capacity of ______________ tank in an airplane.
200 LITERS
two drain masts
forward mast drains wastewater from the forward cabin
aft drain mast drains wastewater from the aft cabin
It comes from the aircraft galleys and from the lavatories sinks.
wastewater drains overboard
It discharges the wastewater from the toilet bowl to the waste storage tank in flight.
Differential pressure
Differential pressure created by the _________________ forces the waste from toilet bowls into the waste storage tank of aircraft.
vacuum generator
It produces the necessary pressure differential while the aircraft is on the ground, and at altitudes below 16000 ft.
vacuum generator
It uses clear water from the potable water system to flush the toilets.
waste system
_____________ in the airplane has a usable capacity of 170 liters.
Waste tank
It is installed under the washbasin in each toilet unit to supply hot water to the water tap.
water heater
It avoids constant aircraft cabin depressurization by opening only when a certain amount of water is collected.

It is used to fill the water in the airplane.
Water Servicing Cart
The ________________ in the airplane contains a fitting for the attachment of a fill hose.
water servicing panel
The _____________ on the panel is used to fill the tank.
quantity indicator
It is plumbed from the top of the tank to the aircraft exterior.
overfill drain line
Lavatory manufacturers have progressed to ___________ technology to eliminate solid and liquid residue from the basin.
vacuum flush
Vacuum flush patented in _______.
1975
They are considered to be less odor-inducing and substantially lighter in weight, saving fuel by reducing the need to carry large reserves of blue recirculating water.
vacuum flush systems
a small lav truck pulled behind a tug
lav cart
It is used to drain the waste from the aircraft waste tank.
Lavatory Service Cart
The aircraft waste tank is drained by pulling the waste drain valve handle on the toilet servicing panel after attaching the ground lavatory service cart to the ____inch drain outlet and removing the drain plug.
