Abstract

An aircraft control system including transducers connected by interface units to an avionics network, such as an AFDX network. Each transducer is directly connected to an interface unit local to the transducer. Each interface unit is a configurable unit and has a signal processing module converting data to a format suitable for transmission over the network. Each interface unit may be configurable, via software commands, to operate in an application session mode, a data-loading mode, or a maintenance mode. Each interface unit may be directly associated with one of the software applications of the aircraft control system. The network may include a lower bandwidth part where data communication is conducted over sampling ports only. Interface units may be configured or installed using a plug and play method.
