This chapter presents the architectures for the transmission/processing of information associated with actuation functions. The “flight control” application is used as the basis for this exploration because it is much more complex, and in many ways richer than other applications. The chapter explains the evolution of flight controls from purely mechanical to all electrical signaling, the Signal‐by‐Wire (SbW) mode. It illustrates the evolution of flight control under the signal aspect. In the designs of conventional flight controls, the pilot's commands move the load exclusively transmitted in mechanical form: “Fly‐by‐Cable” or “Fly‐by‐Rod” versus “Fly‐by‐Wire”. As electrical signaling becomes more reliable, the more it becomes tempting to remove auxiliary actuators. The actuating functions related to landing gears (steering, braking, etc.) have broadly followed the same incremental changes of the flight controls. This development, similar to that observed in the automotive industry, can be illustrated through the example of braking.
