FVA English to French Tech/Engineering Aerospace / Aviation / Space aéronautique (in a patent)

The present disclosure relates to aircraft propulsion systems, 5 and to methods of
operating aircraft involving the management of fuels of different types, including detection of fuel properties and actions taken to improve aircraft performance based on the data acquired, and to methods of modifying aircraft so as to allow such methods to be implemented

The chemically and/or physically determining one or more parameters of the fuel in the fuel tank may be performed by extracting a sample of the fuel from the fuel tank for off-wing testing.

The method may be performed on-wing, e.g. by a fuelling schedule determination
module of the aircraft, which may form a part of an electronic engine controller (EEC) of the aircraft. Alternatively, the method may be performed off-wing, and the fuelling schedule provided to the aircraft for implementation.
