The runway state determined on the ground by an aircraft and provided to the aircraft on approach does not make it possible to account for possible degradation of the runway occurring since the previous determination of that runway state. Updating of this runway state on the basis of a simple comparison between a desired deceleration and an observed deceleration resulting from a degraded runway is not satisfactory either. The disclosure herein thus provides for obtaining a local stopping distance according to a local runway state characterizing a runway zone on which the aircraft is in movement at the time of the landing, this local stopping distance being estimated based on local measurements made in the aircraft; obtaining a reference stopping distance according to a reference runway state; then comparing these two distances with each other to determine whether the local runway state is more degraded than the reference runway state.
