- the requests are transmitted by the communication module 31 to the FMS module 12 in a form encrypted.
- the clone 33 When the clone 33 considers that the corresponding request has led to an abnormal operation of the FMS system, for example when one of the aforementioned conditions is met, the clone 33 returns this request with a non-compliant status to the communication module 31 when l step 155. During the following step 160, the communication module 31 then transmits an error message to the application component 22-1 which sent this request. This message can be sent, for example, with the corresponding request and / or with a full report on the error.
- the communication module blocks the application component 22-1 that sent it.
- the present invention therefore has a number of advantages.
- the invention makes it possible to connect an open world device such as a tablet, for example, to the FMS system in a secure manner.
- the invention does not modify the avionics world and in particular does not modify any component of the FMS system by integrating the set of new components into the open world device. This then allows a particularly simple and easy deployment of the invention in the existing hardware components.
- the invention remains applicable to any avionics system other than the FMS system.
- the clone integrated into the open world device according to the invention is able to reproduce the operation of such an avionics system. It is therefore clear that all of the previous teachings remain applicable in relation to any avionics system.
