The invention relates to an automated system, for example an aircraft flight management system (FMS). If proposes harmonizing the response times of the FMS system between the various scenarios of one and the same family, as and when the product, and its usage context, changes. The system according to the invention comprises several subsystems, the external instruction processing time of which is variable, its response time to one and the same command being independent of the volume of internal and external data manipulated and of the future functional changes, and it is characterized in that it comprises, in each of its subsystems that have variable processing times and/or are likely to change (FPLN, NavDB, TRAJ/PRED, etc.), an explicit resource consuming subsystem (SPARE) simulating a processing time, the duration of which is at least equal to the difference between the maximum processing duration predictable at the end of life of the subsystem that incorporates it and the current processing duration, and a timer subsystem (TIMER) triggered by a processing instruction for which the timer duration is at least equal to the current processing time of said instruction plus the time determined by the explicit resource consuming subsystem.
