Abstract: The present invention relates to a method of generating instruction values for servo-controlling a flight parameter P of an aircraft equipped with an automatic pilot, between a current value C and a target value T. It comprises a phase for determining increasing or decreasing instruction values PC of the flight parameter P and instruction values ( ? P ? t ) C of its time derivative and/or (?Pdt)C of its integral. It also comprises a phase of use, by a servo-control law of the parameter P of the automatic pilot, of each of the instruction values PC, ( ? P ? t ) C and/or (?Pdt)C. It also comprises a phase of use, by the automatic pilot, of the value T as final target value. The instruction values PC, ( ? P ? t ) C and/or (?Pdt)C are calculated from the current value C, the target value T of the parameter P and a time constant ?.
