Claim:
1. An aircraft, comprising: a pressure supply system for a fresh water system including a water reservoir having a bleed air inlet for attaching a bleed air source and a water outlet, and a water pump arranged downstream from the water outlet, a bleed air source connected to the bleed air inlet of the water reservoir, wherein the water pump is configured so as to pressurize water which is loaded with bleed air from the water outlet until a predetermined nominal operating pressure range is achieved; and wherein the pressure supply system has a predetermined minimum operating pressure, the minimum operating pressure being less than the nominal operating pressure range, a bleed air pressure and the water pump is dimensioned in such a way that the bleed air pressure and the water pump each individually provide at least the minimum operating pressure, and the bleed air pressure and the water pump together provide at least a pressure which is within the nominal operating pressure range.
