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.

1. An automated system comprising several subsystems, generating internal data and executing commands, for obtaining a response time for the execution of a command which is independent of a volume of internal or external data manipulated in order to execute said command and independent of future functional changes made to said system,said system comprising, a plurality of subsystems each subsystem having a current processing time, to perform processing by the subsystem in response to an instruction to perform the command, which varies throughout functional changes made to the subsystem during the life of the system, anda maximum processing duration, to perform processing by the subsystem in response to the command predicted for the end of life of the system;an explicit resource consuming subsystem which simulates a processing time, the duration of which is at least equal to, when used in connection with processing performed by a first subsystem included in the plurality of subsystems in response to the instruction to perform the command, a difference between the maximum processing duration for the first subsystem and the current processing time for the first subsystem; anda timer subsystem, used in connection with processing performed by the first subsystem in response to the instruction, for which a timer period is at least equal to the current processing time for the first subsystem plus the duration of the explicit resource consuming subsystem in connection with the processing performed by the first subsystem in response to the instruction. 2. The system as claimed in claim 1, wherein the system is an aircraft flight management system (FMS). 3. The system as claimed in claim 2, in which the first subsystem performs short-and long-term update calculations concerning short-and long-term information that has to be displayed, wherein, after receiving an instruction to display the short-term information, the first subsystem triggers the timer subsystem to count down the timer period, the end of said timer period determining an authorization to display the long-term information.
