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.

Abstract: An avionics system including a first node and a second node wherein the first node is arranged to transmit a data message having: a data identifier, dynamic metadata associated with the data identifier and data content to the second node; wherein the second node is arranged to receive the data message from the first node and to: locate and read the data identifier within the data message; locate and read the dynamic metadata associated with the read data identifier; and retrieve data content from the determined position in the data message, wherein the data message contains multiple data identifiers, each with associated dynamic metadata and associated data content, and the second node is arranged only to locate and read the data identifier and dynamic metadata and retrieve data content in relation to a subset of the plurality of data identifiers.

Abstract: A computer implemented method of defining a data model or schema, and subsequently reading files with said defined data model, the method including: identifying a minimum set of elements required to define the data model; defining the data model having a plurality of elements based on the identified minimum set of elements; for a first data source, or file, having a plurality of elements, and for each of the plurality of elements of the data model determining whether the element of the data model is present in the first data source, or file; and in the event that each element in the data model is identified as being present in the first data source or file, generating an output indicative of the first data source or file conforming to the determined data model.
