Abstract
The aircraft refuelling equipment (20) of an aircraft comprises a pipework (22) in which a fuel supply line (13) is connected to a plurality of tank supply lines, fuel tanks connected to tank supply lines of the pipework, first valves (24, 25,26) allowing each fuel tank to be disconnected from the fuel supply line, and at least one captor (30) that provides a signal indicative of a pressure or a flow rate. For each of said first valves, a first valve flow parameter can be estimated, using said captor. The equipment further comprises:—at least one actuator associated with each of said first valves, the actuator allowing adjustment of the opening of the associated first valve; and an electronic control unit (ECU) connected to the respective actuator-first valve assemblies and adapted to regulate an opening of the first ECU valves, using respective first valve flow parameter data.
