1. A method for piloting an aircraft piloted by an automatic piloting system comprising an input unit enabling a pilot to input at least one corrected speed, a computation unit for determining guidance instructions for the aircraft using a pair of speeds comprising an input corrected speed and a current Mach number, with which is associated a transition altitude, and an automatic piloting device for applying these guidance instructions automatically to the aircraft,
wherein the method comprises: a) automatically detecting a situation in which the aircraft is guided according to a descending corrected speed and a new corrected speed is input by the pilot using the input unit; b) automatically comparing the new corrected speed input by the pilot with the corrected speed used at the current instant for guidance; and c) when the new input corrected speed is greater than said corrected speed used for guidance, automatically replacing said current Mach number with a predetermined maximum Mach number, which is intended to form, together with the new input corrected speed, a pair of speeds which is taken into account by said computation unit for determining the guidance instructions. |
