The flight management computer discloses and carried onboard an aircraft can be programmed with a newly apparent speed constraint while it ensures the guidance of the aircraft in the course of a landing runway approach. It then takes account of the speed constraint by using it as target speed, when it is greater than an instruction speed which depends on the number of extended flap settings and which corresponds to the addition of a further flap setting. If appropriate, the speed constraint may be bounded below, thus making it possible to remain within the limits of the flight domain of the aircraft in its configuration at the time.
