Integrated modular avionics for next generation commercialairplanes

The goals are objectives of integrated modular avionics (IMA) are discussed. One candidate computing architecture for IMA, the Boeing 777 Airplane Information Management System (AIMS), is presented. The cabinet architecture, fault tolerance characteristics, backplane bus, and functional growth provisions are considered. The integration concepts developed for AIMS represent a first step in real-world application of the IMA technologies
