Flight control unit

Block diagram


The flight control unit operates independent of the core flight computers to serve a remote function, often one that is flight critical. Whether it is control surface actuation, sensor aggregation or ancillary system control, we offer a wide range of semiconductor solutions to improve system-level reliability in the harshest conditions.

Design requirements:

Modern flight control unit systems require:

  • Robust, reliable operation.
  • Multiple communications interfaces to many avionic components.
  • Accurate analog conversion for remote sensors.
