Method for controlling an engine controlled by a control device, the control device comprising a first control channel and a second control channel, each control channel comprising a first sensor (CAV1, CAV2) and a second sensor (CBV1, CBV2) each configured to provide respectively a first measurement and a second measurement to each channel, each of the channels comprising an active or passive state defining an active channel or a passive channel, the active channel being intended to drive an actuator of the engine while the passive channel is intended to take over on the active channel in the event of failure of the latter, each channel (V1, V2) comprising: - a measurement consolidation unit (UC1, UC2), each receiving as input the measurements from the two channels via at least one inter-channel communication link (LCOM) so as to obtain a consolidation parameter, - a processing unit (UT1, UT2) for a command (C V1, C V2) of the actuator of the engine, the method being characterised in that it comprises: - during a nominal operating mode of the control device, a step implemented by the processing unit of the active channel comprising a calculation of the command of the active channel (C V1) as a function of the consolidation parameter and of the command of the active channel (C V1) calculated by the processing unit of the active channel at the previous calculation instant, the actuator being controlled by the active channel, and a step implemented by the processing unit of the passive channel comprising a calculation of the command of the passive channel (C V2) calculated by the processing unit of the passive channel at the preceding calculation instant, and - during a degraded operating mode of the control device, a step implemented by the processing unit of the passive channel when the at least one inter-channel communication link (LCOM) is re-established after a cut in the at least one inter-channel communication link (LCOM), comprising a calculation of the command of the passive channel (C V2) as a function of the command of the active channel (C V1) calculated by the active channel at the preceding calculation instant. - a measurement consolidation unit (UC1, UC2), each receiving as input the measurements from the two channels via at least one inter-channel communication link (LCOM) so as to obtain a consolidation parameter, - a processing unit (UT1, UT2) for a command (C V1, C V2) of the actuator of the engine, - during a nominal operating mode of the control device, a step implemented by the processing unit of the active channel comprising a calculation of the command of the active channel (C V1) as a function of the consolidation parameter and of the command of the active channel (C V1) calculated by the processing unit of the active channel at the previous calculation instant, the actuator being controlled by the active channel, and a step implemented by the processing unit of the passive channel comprising a calculation of the command of the passive channel (C V2) calculated by the processing unit of the passive channel at the preceding calculation instant, and - during a degraded operating mode of the control device, a step implemented by the processing unit of the passive channel when the at least one inter-channel communication link (LCOM) is re-established after a cut in the at least one inter-channel communication link (LCOM), comprising a calculation of the command of the passive channel (C V2) as a function of the command of the active channel (C V1) calculated by the active channel at the preceding calculation instant.
