Abstract

The method can include operating the hybrid aircraft power plant in a first mode of operation in which a plurality of controllable parameters including a fuel flow to the thermal engine and an electric power to the electric motor has a first set of values corresponding to a first power output; receiving a requested power output; determining a second set of values of the one or more of the controllable parameters to bring first power output to the requested power output; determining whether said second set of values poses a risk of undesired clutch behavior; and when the second set of values poses the risk, modulating the second set of values to avoid the risk and setting the plurality of controllable parameters to the modulated second set of values.
