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.

Abstract: A water supply system for an aircraft includes a water supply tank, water consumers, a pressurization unit to convey water from the water supply tank to the water consumers, water consumer supply units, each of the water consumer supply units configured to control water supply from the pressurization unit to one of the water consumers, and a controller. Each of the water consumer supply units is configured to output a consumer signal indicating a water supply of the respective water consumer, wherein the controller is configured to receive the consumer signal of the water consumer supply units and to control a flow rate and/or pressure of the pressurization unit depending on the consumer signal.

Abstract: A system for heating up water for a consumer unit in an aircraft, having a water reservoir and a control unit. The water reservoir has a heating device to heat water held in the water reservoir to a consumer temperature. The control unit controls the heating device so water in the water reservoir is automatically heated to or above a disinfection temperature at which germ formation in the water reservoir is eliminated or suppressed, and a temperature of the water in the water reservoir is maintained at or above the disinfection temperature for a disinfection period, the heating to the disinfection temperature being effected only during flight phases or portions of flight phases of the aircraft during which use of the consumer unit by a user is not to be expected. A corresponding method and an aircraft having such a system are disclosed.

Abstract: An aircraft with a drinking water supply and distribution system including a water storage tank, a consumer equipment, a pressurizer, a pressure reducer and a conduit system connecting the drinking water storage tank to the consumer equipment via the pressurizer and supplying water from the at least one water storage tank to the at least one consumer equipment. The pressurizer pressurizes water in the conduit system with a peak pressure exceeding a supply water pressure threshold. The conduit system includes flexible conduits having a maximum internal diameter of less than 8 mm. The pressure reducer is provided for reducing the pressure of water supplied to the consumer equipment below a consumer water pressure threshold. The supply water pressure threshold exceeds the consumer water pressure threshold.
