Abstract: A method for operating an on-board water supply and distribution system of an aircraft for supplying water includes a central tank, consumer assemblies with a supply device and a buffer tank, pump operable in a supply mode and reverse mode, filter device, and high-pressure conduit system. The central tank connects to the pump's upstream side. The conduit system connects the downstream side and consumer assemblies. The pump in supply mode delivers water from the downstream side to the buffer tank. In reverse mode, the pump can convey water from the downstream side to the upstream side. The method includes operating the pump in supply mode so water from the central tank goes to a consumer assembly in a first time interval to fill the buffer tank, and operating the pump in reverse mode in a second time interval so water from the buffer tank passes through the filter device.

Abstract: A method for operating an on-board water supply and distribution system of an aircraft for supplying water includes a central water tank, first consumer assemblies with buffer tanks each including a heater to heat up water in the buffer tank to a disinfection temperature, pump having upstream and downstream sides to operate in supply and reverse modes, and high-pressure conduit system. The central water tank connects to the pump's upstream side. The conduit system connects the downstream side with a first consumer assembly. The method includes operating the pump in supply mode where water from the central tank goes to a first consumer assembly to fill a buffer tank, operating a buffer tank heater so water heats to a predetermined disinfection temperature, and operating the pump in reverse mode so heated water passes through a part of the conduit system and the upstream side of the pump.
