Abstract:
1. A computer for computing flight commands within a flight control system, the computer comprising: at least one item of software for computing flight commands according to at least one flight law on the basis of at least one command received from at least one piloting member; a communication network device with at least two separately associated computers of the same type; a first computing unit for computing a first flight order, intended for a remote controller of an airfoil actuator, in command mode within a first virtual command/monitor pair comprising said computer and one of the at least two separately associated computers acting in monitor mode on behalf of said first virtual command/monitor pair; a separate, second computing unit for computing a second flight order, intended for a remote controller of an airfoil actuator, in monitor mode within a second virtual command/monitor pair comprising said computer and the other of the at least two separately associated computers acting in command mode on behalf of said second virtual command/monitor pair, wherein each flight order is computed at least twice by said first and second computing units, a first time in command mode by said first computing unit, and a second time in monitor mode by said second computing unit, for achieving software dissimilarity.
