Abstract: A target vertical speed, to be applied to the aircraft upon the initiation of the aircraft's flaring phase, is defined in relation to the ground. An optimized ground slope associated with an approach path to be tracked during the landing, is then determined as a function of the determined target vertical speed and of at least one outside parameter. This optimized ground slope is at least equal to a predefined ground slope. Upon interception by the aircraft with the approach path, the aircraft is guided to track the determined optimized ground slope associated with the approach path and reach the target vertical speed upon initiation of the flaring phase.

Abstract: According to the invention, a target vertical speed (Vzo), defined in relation to the ground, is determined and an optimized ground slope (?o), associated with an approach path (A) to keep track during the landing, is determined on the basis of said determined target vertical speed (Vzo) and of at least one outside parameter, said optimized ground slope) (?o) being at least equal to a predetermined ground slope (?i).
