The focus here is put on the IFE system itself. The objective is to set the boundaries and provide a clear vision of the need.

The [MCB] All Missions and Capabilities diagram shows on the capabilities of the IFE system. Three other diagrams provide interesting entry points to the model:

• [SC] System Actors lists all the Actors (the aircraft is considered as an actor)
• [SDFB] Top Level Functional Overview provides a first functional overview of what the actors actually do and what kind of exchanges they have with the IFE system
• [SAB] Top Level System Overview and its slightly refined version [SAB] High Level System Overview are very good entry points to further navigate in the model.

Starting from these high level diagrams, a typical reading path is to dive into the function to visualize their refinement. For example, [SDFB] [CTX] Run Services. And recursively.

Using capabilities as a driver to browse the model is recommended. Some diagrams are specifically marked for that purpose, for instance [SDFB] [CAPABILITY] Provide Video Entertainment Services. From this capability covering VOD services to the passengers, browse the functional chains and scenarios to better understand how the capability is fulfilled.

• Functional chains: [SFCD] Start Playing VOD Movie, [SFCD] Resume VOD Movie
• Scenarios: [ES] Start VOD Service, [ES] Start Playing VOD Movie

Check the global mode machine of the system with [MSM] IFE Operating Modes. Among others, this mode machine is intended to specify under which operational conditions the IFE system is running. Another Mode machine is specifically modelled for what will become the Seat TV: [MSM] Seat TV - Movie Player Modes
