During your next custom Data Concentrator (DCU) development, imagine you could prototype your design in hardware well in advance of the DO-178/254 design phase, not once but multiple times. This would give you the ability test your DCU or remote interface unit (RIU) with its eventual interface systems, allowing you to catch bugs very early and refine your design to the nth degree. When DO-178/254 design of custom units begins, you are not just working off a paper specification, you have working hardware and you have hugely mitigated program risks.
Curtiss-Wright provide a multi-phase development flow that allows developers to realize early designs using a modular approach. This modular architecture allows for rapid prototyping, validation and robust specification capture prior to DO-178/254 design phase. This paradigm retains the adaptability of a modular system allowing unique specification LRUs to be realized without the development costs associated with a new bespoke unit.
