1. An automated method performed by a control system to control the amount of lift produced during flight of an aircraft in response to a control signal received in response to a manual activation of a control column of the aircraft by a pilot, wherein the aircraft comprises at least one elevator and at least one lift generator that directly modifies the amount of lift produced during flight and that is a separate control surface from the at least one elevator, the method comprising: extracting, by the control system, a limited portion of the control signal;generating, by the control system, at least one command instruction for the at least one lift generator of the aircraft based upon the limited portion of the control signal;calculating, by the control system, at least one deflection instruction of the at least one elevator of the aircraft from a remaining portion of the control signal that remains after the limited portion is extracted; andapplying, by the control system, the at least one calculated deflection instruction to the elevator of the aircraft and the at least one command instruction to the at least one lift generator of the aircraft so as to modify the amount of lift produced during the flight of the aircraft in response to the control signal. 2. The method as claimed in claim 1, wherein the at least one lift generator comprises a pair of lift generator elements arranged symmetrically with respect to a vertical plane of symmetry of the aircraft, and wherein the applying comprises applying the at least one command instruction in symmetrical fashion to the pair of lift generator elements. 3. The method as claimed in claim 1, wherein the lift generator is an aerodynamic surface that can initially be deflected in only one direction, and that, prior to the generating, is subject to partial deflection, the command instruction being applied relative to this partial deflection. 4. The method of claim 1 wherein the extracting and generating are performed during in-flight refueling of the aircraft. 5. An aircraft flight control system to control an amount of lift produced during flight of an aircraft in response to a control signal received in response to a manual activation of a control column of the aircraft by a pilot, wherein the aircraft comprises at least one elevator and at least one lift generator that directly modifies the amount of lift produced during flight and that is a separate control surface from the at least one elevator, the control system comprising: a first calculation system configured to extract a limited portion of the control signal, to calculate at least one command instruction of the at least one lift generator of the aircraft based upon the limited portion of the control signal, and to provide the calculated at least one command instruction to thereby actuate the at least one lift generator; anda second calculation system configured to calculate a deflection instruction of the elevator using a remaining portion of the control signal that remains after the limited portion is extracted from the control signal, and to provide the deflection instruction to thereby actuate the at least one elevator;wherein, when the corresponding deflection instruction and the corresponding command instruction are applied to the elevator and to the at least one lift generator element, respectively, the amount of lift is produced during the flight of the aircraft in response to the control signal. 6. The system as claimed in claim 5, wherein the at least one lift generator comprises a pair of lift generator elements arranged symmetrically with respect to a vertical plane of symmetry of the aircraft. 7. The system as claimed in claim 5, wherein the at least one lift generator element is an aerodynamic surface of the aircraft adapted to modify the lift of the aircraft during in-flight refueling of the aircraft. 8. The system as claimed in claim 7, wherein the aerodynamic surface of the aircraft comprises at least one of:a spoiler of the aircraft; andan aileron of the aircraft. 9. The system as claimed in claim 5, wherein the at least one lift generator element comprises a micro-thruster adapted to generate an action modifying the lift of the aircraft. 10. The system as claimed in claim 5, wherein the at least one lift generator element of the aircraft comprises a spoiler, wherein the second calculation system comprises a memory that stores a pre-deflection amplitude of the spoiler, and wherein the second calculation system initially pre-deflects the spoiler to thereby allow subsequent deflection of the spoiler in two directions. 11. The system of claim 5 wherein the extracted portion of the command signal and the remaining portion of the command signal are defined so that, when the corresponding deflection instruction and the corresponding command instruction are applied to the at least one elevator and to the at least one lift generator element, respectively, a same amount of lift is generated as if a deflection instruction determined from the whole of the command signal were applied only to the at least one elevator. 12. An aircraft comprising: an elevator configured to respond to a first actuator to produce a first amount of lift during flight of the aircraft;a lift generator configured to respond to a second actuator to produce a second amount of lift during the flight of the aircraft using a separate control surface from the elevator;a control column that produces a control signal that indicates a total amount of lift to be produced in response to a manual activation of the control column by a pilot of the aircraft; anda control system coupling the control column to the first and second actuators to thereby actuate the elevator and the lift generator, respectively, in response to the control signal during flight of the aircraft, wherein the control system comprises: a first calculation system configured to calculate a command instruction based upon a limited portion of the control signal that is applied to the second actuator to actuate the lift generator and to thereby produce the second amount of lift during the flight of the aircraft; anda second calculation system configured to calculate an elevator deflection instruction using a remaining portion of the control signal that remains after the limited portion is extracted from the control signal that is applied to the first actuator to actuate the elevator and to thereby produce the first amount of lift during the flight of the aircraft. 13. The aircraft of claim 12 wherein the first calculation system is active during in-flight refueling of the aircraft to calculate the command instruction and to apply the command instruction to thereby actuate the lift generator during the in-flight refueling of the aircraft. 14. The aircraft of claim 12 wherein the lift generator comprises a pair of lift generator elements arranged symmetrically with respect to a vertical plane of symmetry of the aircraft. 15.
