Claim Text:
1. A method for piloting an aircraft for approach to final descent, said aircraft being provided with wings having leading-edge high-lift slats and trailing-edge high-lift flaps, said slats and flaps being controllable by a control lever, wherein said method comprises the steps of: maintaining said slats and said flaps in a retracted position prior to the approach to the final descent; adjusting the aircraft to a first configuration as said aircraft begins said approach to the final descent and aircraft speed falls below a first predetermined speed value, wherein the first configuration is produced by both extending and inclining said slats from the retracted position, while maintaining the flaps in the retracted position; adjusting the aircraft to a second configuration as said aircraft follows said approach to the final descent and aircraft speed falls below a second predetermined speed value that is less than said first speed value, wherein the second configuration is produced by both extending and inclining said flaps relative to the position of the flaps in the first configuration, while maintaining said slats substantially as in the position of the slats in said first configuration; and conferring on said wings, while said control lever is in a position corresponding to said first configuration and said aircraft crosses a first speed threshold greater than said second predetermined speed value, an intermediate configuration, wherein the intermediate configuration is produced by maintaining said slats in an extended and inclined position substantially as in said first and second configurations, and extending the flaps less than in said second configuration and greater than in said first configuration; and retracting the flaps to a configuration substantially as that of the first configuration while said wings are in said intermediate configuration and aircraft speed crosses a second speed threshold greater than said first speed threshold.
