Digital data communication is a key technology for tight integration of safety-critical systems in more electric aircraft. Data communication components represent only a fraction of the total aircraft costs, but determine the ability of integrators and suppliers to create system architectures at lower lifecycle costs. The reduction of economic costs throughout the system lifecycle can be significantly supported by time-triggered integration technologies with additional services which operate an embedded system as one fault-tolerant distributed computer. This approach reduces the effort and costs to be expended on the design, certification, maintenance and reuse of a complex set of integrated systems. This paper reveals how control subsystem platforms profit from high-level distributed embedded computing services built into the Time-Triggered Protocol (TTP). The Time Triggered protocol (TTP), an open technology for the design of distributed control systems, is well suited to reduce the lifecycle and reuse costs expended for control systems in more electric aircraft. TTP, at protocol level, provides different mechanisms supporting the design of control systems on the basis of the distributed embedded computing paradigm: built-in system health monitoring, redundancy management and data integrity services true modularity, layering and encapsulation fault isolation and system-level partitioning strict control of key system interfaces in the time and value domain autonomous operation of the communication system independently of the application.
