  • Method and system for protecting an aircraft against an incoherent command instruction
    Patent number: 11467837
    Abstract: A method and system for protecting an aircraft against an incoherent command instruction. The system has a generation unit generating a command instruction transmitted to an evaluation unit that evaluates whether or not the command instruction is incoherent and generates and transmits a validation order if the command instruction is coherent or an arbitration request if not, the arbitration request being transmitted by an arbitration unit, where applicable, to an operator who sends a confirmation response or a cancellation response. The arbitration unit generates and transmits a validation order to an execution unit in the event of receiving a confirmation response and a cancellation order in the event of receiving a cancellation response, the system allowing the execution unit to execute only the command instructions evaluated and confirmed as not being incoherent.
