1. An open world device for remotely communicating with an avionics system of an aircraft, the open world device comprising:
at least one application processor configured to send requests to the avionics system that remotely communicates with the open world device and to receive data from the avionics system; and
an interface comprising communication circuitry configured to intercept each of the requests sent by the at least one application processor, and
a software-clone of the avionics system configured to test each of the requests intercepted by the communication circuitry in order to determine a status of a respective request of the requests between a conforming status and a non-conforming status, the clone determining the conforming status when the clone determines that execution of the intercepted request would lead to a normal operation of the avionics system, the clone determining the non-conforming status when the clone determines that execution of the intercepted request would lead to one of: (i) an abnormal operation of the avionics system, and (ii) at least one abnormal resultant datum, wherein the communication circuitry is configured to send only requests having the conforming status to the avionics system.
