1. A protocol converter system comprising:

  • a digital interface circuit which is adapted for connection to a digital data bus, the digital interface circuit receiving flight control information from the digital data bus and operating in response to the received flight control information to output at least one first digital flight control signal representing the received flight control information;

    an analog interface circuit coupled to receive at least one second digital flight control signal from a digital data processor, the analog interface circuit operating in response to each received second digital flight control signal to generate and output an analog flight control signal commanding an aircraft analog flight control computer to execute a maneuver commanded by the received second digital flight control signal; and

    the digital data processor coupled to receive the at least one first digital flight control signal from the digital interface circuit, the digital data processor generating and outputting in response to each received first digital flight control signal one of the at least one second digital flight control signals representing the flight control information represented by the first digital flight control signal.
