As it progresses, Signal‐by‐Wire (SbW) has increased the total amount of data being exchanged, as well as the number of communication units and the number of interactions taking place between these units. This signal traffic has had to grow with improved flexibility, scalability and reliability of complex and critical systems. Two major changes have helped achieve these goals: the first being the massive use of digital data networks and second being the introduction of integrated modular avionics. With full SbW architecture, data is exchanged in electrical form between sensors, actuators, computers and human‐machine interfaces. This chapter shows that other methods for the transmission of data exist aside from electrical ones. It discusses how the evolution of SbW (partial and complete, analog and digital, federated and modular) has gradually facilitated geometric integration, to increase the performances of existing functions and/or enabled new functions to be implemented.
