The flight control system comprises: at least one actuator (13) for a mobile surface of the said aircraft;a flight control module (12) in communication with the said actuator (13), the said module comprising at least a first and a second computer (14-1, 14-2, 14-3, 15-1, 15-2, 15-3), each computer b
The flight control system comprises: at least one actuator (13) for a mobile surface of the said aircraft;a flight control module (12) in communication with the said actuator (13), the said module comprising at least a first and a second computer (14-1, 14-2, 14-3, 15-1, 15-2, 15-3), each computer being adapted for calculating a control command established according to at least one predetermined law for control of the said flight surface; the said actuator (13) comprising logical means (18, 19) adapted for comparing the commands of the said computers (14-1, 14-2, 14-3, 15-1, 15-2, 15-3) and for determining on the basis of these commands the action to be executed on the said mobile surface. The aircraft comprises such a system.

1. A flight control system for an aircraft, comprising: at least one actuator to actuate a mobile flight surface of the said aircraft;a flight control module in communication with the said actuator, and comprisingat least a first and a second single-path computer, each configured to calculate a control command established according to at least one predetermined law for control of the flight surface, the first and second single-path computers being connected to the actuator via a control path and a monitoring path, commands to cause an action to be executed on the mobile surface being provided to the actuator via the control path, the monitoring path being used to provide comparison values to the actuator to determine whether the commands received via the control path are valid,wherein said actuator comprises logic in the control path to compare commands received from the computers via the respective control and monitoring paths and to determine on the basis of these commands an action to be executed on the mobile surface, andthe logic includes a voting architecture, the first computer belonging to a first group of computers, the second computer belonging to a second group of computers and the voting architecture having a first voting level for each of said first and second groups and a second voting level at outputs the first and second groups. 2. The flight control system according to claim 1, wherein the logic the actuator is further configured to send back or not send back, for each computer, a failure message depending on the result of the comparison of the commands. 3. The flight control system according to claim 2, further comprising: a plurality of actuators,wherein the first and second computers are further configured to be disabled when a number of actuators exceeding a predetermined number send back the failure message. 4. The flight control system according to claim 3, wherein logic of each actuator is configured to, when all computers that are not disabled calculate the control command according to a same program, send a software reconfiguration request to one of the computers that are not disabled to cause the one of the computers that are not disabled to function according to a program different from a program of the other of the computer that are not disabled. 5. The flight control system according to claim 1, wherein each actuator comprises a control unit in the control path and a monitoring unit in the monitoring path to monitor the control unit. 6. The flight control system according to claim 5, wherein both the command unit and the monitoring unit are connected to the first computer and to the second computer. 7. The flight control system according to claim 5, wherein the control units is only connected to the first computer and the monitoring unit is only connected to the second computer, the command and monitoring units also being connected to one another. 8. An aircraft equipped with a system according to any one of claims 1 to 7. 9. The flight control system according to claim 1, wherein a hardware architecture of the first computer is different from a hardware architecture of the second computer. 10. The flight control system according to claim 1, wherein the first single-path computer computes control commands using one of a normal law and a direct law, and the second single-path computer computes control commands using a direct law different from the direct law used by the first single-path computer.
