TTTech, based in Vienna, Austria, was selected by Rockwell Collins to provide hardware and software products based on the Time-Triggered Protocol TTP for the Bombardier CSeries flight control computer system.
TTP, an open SAE standard "SAE AS6003 – TTP Communication Protocol," has a bandwidth of up to 20 Mbit/s per channel and is a significant performance improvement compared to CAN, Mil-Std-1553 and ARINC 429, according to TTTech. Additionally, TTP provides enhanced fault isolation, system health monitoring and redundancy management.
"Being selected by Rockwell Collins – a leading provider of advanced flight control systems – proves once again that the TTP technology perfectly fits today’s and future requirements for enhanced airborne control systems," said Georg Kopetz, member of the executive board, TTTech Computertechnik AG. "We are confident that our products will help Rockwell Collins to carry out development of the flight control computers in a smooth and cost-efficient way."
