The flight control computer is at the core of any modern aircraft, both manned and unmanned. In both cases the typical flight control computer drives the primary flight control surfaces to drive the flight path of the aircraft but also provides finer control for stability. Given the criticality of this function these computers are often used in a dual or triple redundant configuration and subject to strict compliance to safety standards for software and hardware such as DO-178C and DO-254.
Curtiss-Wright has provided a number of flight controls systems using the wide range of products available in our portfolio. At the core are the processors used which are a key part of the loop closure for the control system which mandates that they are highly reliable, deterministic and high performance. A wide range of Curtiss-Wright Power Architecture SBCs readily provide this function. In addition to this, a wide range of interface are required, from ARINC429, various discrete and analog I/O, serial interfaces and a cross-channel data link (CCDL) to facilitate redundancy. All of the these, provided in a fully integrated LRU that is qualification and flight tested using the best embedded electronics in the industry.
