Embraer Legacy 450 and Legacy 500 Fly-by-Wire Systems with TTP

Embraer's Legacy 450 and Legacy 500 business jets are the only aircraft in their segment equipped with advanced fly-by-wire electronic flight controls. The digital fly-by-wire system includes aileron, elevator, and rudder actuators; remote electronic units; and a flight control computer. The flight control computer is being developed by BAE Systems and Parker and provides a lightweight, high-integrity solution that reduces fuel consumption and pilot workload. In November 2012, the Legacy 500 made a successful first flight. Deliveries of the first aircraft are expected to begin in 2014.

TTTech provided commercial off-the-shelf (COTS) products based on TTP for the aircraft's flight control computer. TTP is designed as a modular distributed platform technology with additional functions for enhancing fault isolation, system health monitoring, and redundancy management. This helps to reduce system complexity, simplifies software design and certification, enables reuse, and facilitates faster time-to-market.
