Abstract
A flight control system for an aircraft comprises a set of actuators for controlling the aircraft and a set of flight control computers only made up of a set of duplex type main computers and of at least one backup computer. All the main computers are configured to implement auto-pilot laws for the aircraft. The set of main computers comprises two computers from a first hardware type, configured to control actuators of the set of actuators as per a first tolerance level and two computers from a second hardware type, different from the first hardware type, configured to control actuators of the set of actuators as per a second tolerance level, less stringent than the first tolerance level.
