This recorded webinar presents how hardware-in-the-loop (HIL) testing is used to develop, test, and validate new aircraft components or systems such as controllers for aileron actuators. State-of-the-art development and certification workflows are presented, including the tools necessary to perform them. The example of a flight controller demonstrates the seamless transition from desktop simulation to real-time testing. During the webinar, you will learn how a digital twin enables you to tackle the challenges of the electrification of your more electric Aircraft. Finally, the toolchain for successfully integrating automated testing and an iron bird in the certification workflow will be explained.
