Advanced Integrated Systems for Optimized Aircraft

The reduction of system lifecycle costs and aircraft operating costs without compromising the safety of air travel, is the imperative in design of more capable and optimized aircraft systems.

New innovative integrated aircraft systems and avionics are developed to optimize and enable new capabilities, reduce SWaP (size, weight and power), maximize fuel efficiency and reduce system and ownership costs.

Aerospace switches and other flight and rugged hardware integrated aircraft systems

Our Focus: Advanced Integrated Systems and Deterministic Integration

TTTech provides system integration capabilities, deterministic networks (AFDX®, TTEthernet®, TTP®),  platform components and methodology required for design and integration of advanced integrated aircraft systems.
