WARRENDALE, Pa., 7 Dec. 2008. Officials on SAE International's AS-2 Embedded Computing Systems Committee announced they are developing a new avionics and overall aerospace standard that will help simplify the design of advanced integrated systems using time-triggered protocol (TTP), resulting in system lifecycle cost savings.

TTP is one of the core technologies for design of open time-triggered architecture (TTA) and generic control system platforms for deterministic, modular, scalable, and reusable aerospace systems, SAE officials say. It helps reduce system complexity and lifecycle costs in safety-critical, fault-tolerant and distributed on-board systems. TTP is selected for integration of key systems in commercial aircraft such as Airbus A380 and Boeing 787, as well as military jets.

The new SAE AS6003 "TTP Communication Protocol" standard will protect past and ongoing system design investments and simplify design, system integration, and incremental modernization of open aerospace and defense systems and architectures, organization officials say.

SAE International's AS-2 Embedded Computing Systems Committee addresses all facets of embedded computing systems – design, maintenance, and in-service experience. The committee is part of SAE International's Avionic Systems division.

The organization provides some of the key system architecture, design, and networking standards; reports; and recommended practices for commercial and military avionics.SAE International is a global association of 115,000 engineers and related technical experts in the automotive, aerospace, and commercial-vehicle industries.
