Abstract: A method for operating an on-board water supply and distribution system of an aircraft includes a central water tank, central pump, consumer assemblies each including a supply device to supply water, and a high-pressure conduit system. The high-pressure conduit system connects the downstream side and consumer assemblies and is configured where the central pump can deliver water from the downstream side to the consumer assemblies. The method includes operating the central pump where water in the high-pressure conduit system is pressurized to a predetermined first pressure, operating the consumer assemblies where in each of the consumer assemblies the connection between the buffer tank of the consumer assembly and the high-pressure conduit system is in a closed position, monitoring pressure for a predetermined first period of time, and providing a first failure signal when pressure drops below a predetermined second pressure within the first period of time.

Abstract: A method for draining a water supply system onboard an aircraft which supplies water from a central water tank to consumers. Water is supplied by a supply pump from the central water tank through supply lines of a conduit system to consumers. Each consumer is associated with a supply valve for drawing water from the conduit system. The supply lines have a maximum internal diameter of 8 mm or less. The method includes closing the supply valves of all consumers, subjecting the supply lines of the conduit system at the at the supply pump to a draining pressure and sequentially opening the supply valves of all consumers for removing water from the supply lines of the conduit system. A corresponding water supply system and an aircraft are disclosed.

Abstract: A high pressure water supply system for an aircraft includes a main water supply tank, water consumers, pressurization units configured to convey water from the main water supply tank to the water consumers, and a controller. One pressurization unit of the pressurization units conveys water to a first subset of water consumers of the water consumers via a corresponding high pressure water supply line, and the controller is configured to control an output pressure of the one pressurization unit depending on a hydraulic resistance length of the high pressure water supply line.

Abstract: A method and system for operating an aircraft on-board water supply and distribution system for supplying water includes a central water tank, first consumer assembly with a supply device and buffer tank to supply fluid via the supply device. Each buffer tank has a treatment inlet for receiving a treatment medium into the buffer tank. A pump has an upstream side and downstream side to operate in a supply mode and reverse mode, and a high pressure conduit system. The central water tank is connected to the pump's upstream side, and the high pressure conduit system connects the downstream side with the first consumer assembly, the conduit system configured so the pump operating in supply mode can supply fluid from the downstream side to the buffer tank of each first consumer assembly, and in reverse mode can draw fluid from the high pressure conduit system towards the upstream side.

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.
