Abstract
The present disclosure relates to a method of operating an aircraft system, in particular for the purpose of fresh air supply, air-conditioning and pressurization of an aircraft cabin, having a first compressed air source formed by a first compressor charged with ambient air, ram air and/or precompressed air and driven by means of at least one motor and/or of at least one turbine and whose outlet is in direct or indirect communication with an aircraft cabin, said aircraft system having at least one second compressed air source whose outlet can be connected directly or indirectly to the aircraft cabin, wherein only the first compressed air source is in communication with the aircraft cabin in a first operating mode, wherein both the first and the second compressed air sources are in communication with the aircraft cabin in a second operating mode, and wherein the selection of the operating mode depends on the pressure of the ambient air such that the first operating mode is set at a high pressure of the ambient air and the second operating mode is set at a pressure of the ambient air lower in comparison.
