SLAT Motor Control
The SLATs are part of the Secondary Flight Control System. They are extended from the leading edge of the wings during take-off and landing to provide additional lift.
The power electronics hardware development is governed by the strict guidelines of RTCA DO-254. Meeting the customer's requirements regarding weight and performance was a major challenge.
In addition to the SLAT MCE unit, Silver Atena also developed the necessary HIL test systems and test benches.
