Claim 19:
20. A control system for a high lift assembly comprising at least one flap of a trailing edge of an aircraft, the high lift assembly being controllable into at least two different aerodynamic configurations of different lift, the control system comprising:
a manual control device operable by an aircraft pilot, the manual control device comprising at least one movable member and a base body, the movable member being movable relative to the base body;
the movable member being movable relative to the base body between positions including a rest position and a distinct first position and second position, the manual control device comprising a device for resiliently returning the movable member to the rest position, the manual control device being suitable for emitting at least one signal representative of the position reached by the movable member with respect to the base body, when the movable member reaches either the first position or the second position, in order to cause the high lift assembly to switch between two of the aerodynamic configurations,
wherein the high lift assembly is configured to be controlled into at least three different aerodynamic configurations of increasing lift;
the manual control device being configured, when the movable member reaches the first position from the rest position, to output at least one signal representative of the reaching of the first position to change the high lift assembly from a current one of the aerodynamic configurations to another of the aerodynamic configurations having a lift greater than the current aerodynamic configuration;
and the manual control device being configured, when the movable member reaches the second position from the rest position, to output at least one signal representative of the reaching of the second position to change the high lift assembly from a current one of the aerodynamic configurations to another of the aerodynamic configurations having a lift less than the current aerodynamic configuration.
