A flight control system includes at least one actuator for a mobile flight surface of an aircraft, and a flight control module in communication with the actuator. The module includes a first and a second computer. Each computer calculates a control command established according to at least one predetermined law for control of the flight surface. The first computer, known as validating computer, comprises logic means adapted for comparing its control command with that of the second computer, known as master computer, and for transmitting the result of the comparison to the actuator. The actuator comprises logic means adapted for deciding, on the basis of the result, to execute or not to execute the command of the master computer. An aircraft comprising such a system is also disclosed.

Flight control system and aircraft comprising it

The flight control system comprises: The aircraft comprises such a system.

The invention relates to a method for the transmission of data relating to the actuation of a member used to operate a vehicle, in which code words are transmitted along the length of a given channel, each of said code words resulting from the channel coding of a block of information symbols that is representative of the aforementioned data. According to the invention, at least two such successive blocks of information symbols are coded using two different codes. The invention also relates to a data transmission system that is used to implement said method.
