Definitions
- the invention relates to the field of embedded systems on aircraft and particularly that of flight control and online maintenance.
- a concrete example is that during a cruising flight phase, where a pilot must divert to an airport different from that of its destination or even that of diverting the initial flight plan.

- pilots must include related information on the airport diversion, namely:
- such an architecture must also allow a connection between portable devices present in the cockpit and existing avionics equipment and also allow a two-way communication with the ground.
- such an architecture must be sufficiently robust in terms of security not to be polluted or deviated because the transported data are sensitive data, specific to an airline and its operations.

- Type solutions (EFB) are associated with a ground station integrated in the flight operations of the airline or a service provider.
- the applications developed for the systems (EFB) are on heterogeneous platforms on the one hand of the operating system and on the other hand on the hardware corresponding to the operating system. They are therefore specified and developed for a given platform and are therefore dependent on the platforms and only work on those for which they are intended.

- the available interfaces may be Wi-Fi interfaces for communications to tablets operating as a remote Dialog Unit (UD) or support for native embedded applications, or Bluetooth interfaces to allow communication with maintenance applications, particularly applications. online maintenance.
- Other interfaces may be implemented to communicate with ground-based servers (118), such as a 3G interface, an LTE interface, or an Ethernet interface to name but a few.
- the WiFi and Bluetooth ports are sized in their frequency and amplitude ranges of their spectrums so that no on-board equipment is disturbed during the start of these functions.
- the open world module further comprises a central processing unit (116) for managing all the input / output operations.
- the avionics and open world modules are coupled by serial or parallel communication links (120) to allow exchanges between the two modules.
