In new aircraft programs, databuses can be on of the key technologies to support a shorter time-to-market and improve program profitability. The new SAE Standard AS6003, Time-Triggered Protocol (TTP), and its DO-254 certifiable chip IP have the potential to significantly impact the design of modern avionics and control systems. TTP supports the reduction of system complexity, thus lowering design and integration costs. Moreover, it facilitates data distribution between Integrated Modular Avionics (IMA) and subsystems.
TTP is already used in several aircraft production programs, including a recent modernization program for the F-16 fighter, as well as Airbus A380, Boeing B787 Dreamliner, Bombardier C Series, and Embraer Legacy 450/500.
