Avionics Systems Integration
The combining of a number of avionic sub-systems is known as avionics systems integration (ASI). It is explained that key to ASI has been the development of data buses, standards and computing power.
Data bus systems can be divided into electrical and optical systems. As an example of an electrical system, MIL STD 1553 is explained in detail. The ARINC 629, STANAG 3910, Parallel and Avionics Full Duplex Switched Ethernet (AFDX) data buses are also mentioned. For optical data bus systems, fibre optic theory and the advantages and disadvantage of multi-mode and single mode optical fibres are explained.
It is described how the development of ‘weapon systems’ for military aircraft and the adoption of ARINC specifications for civil avionics facilitated the development of federated architectures. In these, a number of functionally independent sub-systems are interconnected with some degree of central computer control. However, the availability of affordable high-speed data buses, such as AFDX or STANAG 3910, and powerful computers has enabled the development of integrated modular avionics (IMA) architectures. These employ the ‘three-layer stack’, with hardware, operating system and application layers. It is described how they provide increased performance, capability and availability, but with less maintenance resulting in reduced costs. The final section discusses the application of commercial off-the-shelf hardware and software.
