A method of failure simulation for an aircraft (7) having a power plant (10) with at least two turbine engines (11, 12), together the two engines develop an overall power, each engine (11, 12) being capable of delivering at least one contingency power in order to compensate for a total failure of other engines (11, 12). The device serves during a failure simulation to modify the overall power delivered by the power plant, with this modification being performed with the help of first adjustment means (20). Second adjustment means (30) serve to modify also the difference between the minimum power obtained during the simulated failure and the stabilized overall power, and also the time between said failure stabilizing on said overall power.
