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

Abstract: A method for draining a local water distribution system including a buffer, supply lines connecting one or more consumers to the buffer and consumer valves associated with the one or more consumers. The buffer is configured for locally storing water from an aircraft water supply system to be distributed to the one or more consumers. Water from the buffer can be dispensed through a consumer of the one or more consumers by opening the consumer valve associated with the respective consumer. Water is drained from the supply lines by opening the consumer valves. Water is drained from the buffer through one of the supply lines and the consumer valves or through a drain valve connecting the buffer to a wastewater system of an aircraft. A corresponding local water distribution system and an aircraft are disclosed.

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.

Abstract: A drain mast for an aircraft for discharge of water from the aircraft interior with a line which extends in a line direction from a connector end to a discharge end. The connector end can connect to another line in the interior of the aircraft, through which further line water flows into the drain mast. The discharge end can discharge water into a surrounding area of the aircraft. The line includes a plastic, into which a conductive material is embedded, by which the line can be heated electrically, by a heating current being conducted through the conductive material. A proportion of the embedded conductive material in the line increases in the line direction per length unit from the connector end of the line towards the discharge end such that the heating power which is introduced into the line per length unit increases from the connector end towards the discharge end.

Abstract: A water supply system for an aircraft having consumers with buffer stores connected to a water tank by lines and a pressure source. Each consumer has a filling valve between the buffer store and the pressure source. The buffer store can be filled by opening the filling valve. In each consumer, water can be removed from the buffer store by opening a consumer valve. Each consumer transmits at least one state parameter describing a state of the buffer store of the respective consumer to a control system. The control system controls opening and closing of the filling valves of the consumers taking into account the transmitted state parameters such that removal of water from the water tank by the pressure source does not exceed a threshold value at any point in time. An aircraft having a water supply system and method for controlling a water supply system are disclosed.

Abstract: A pressure supply system for a fresh water system is provided. The pressure supply system includes a water reservoir having a bleed air inlet and a water outlet. The pressure supply system also includes a water pump so as to load water, which is loaded with bleed air pressure, with a further pressure downstream until a predetermined nominal operating pressure range is achieved. As a result, the pressure supply system provides an increased redundancy by pressure generator assemblies which are based on different pressure generation principles.
