Agile Development of a Common Engine Software Interface

Avilution proposes to further enhance its commercially available eXtensible Flight System (XFS) to provide a FACE™ 3.0 aligned Transport Service (TS) supporting the capture, display and use of data from multiple engine Full Authority Digital Engine Controls (FADEC) and similar systems. Avilution already provides a software platform for the creation of avionics solutions which leverages a compact, simple code base with powerful user supplied configuration to support rapid, iterative development of avionics systems for multiple types of aircraft. Rather than a complex monolithic program, Avilution created XFS as a collection of microservices built around a common platform and interface library with a common data model. Unlike traditional solutions, the XFS product is licensed to its customers as software (including any available relevant certification artifacts) on a once-per-serial number of aircraft cost model. This allows the end customer to further enhance the product through configuration or even code changes without the requirement that Avilution be involved. The model also encourages maximum usage and utility of the software without a cost penalty. XFS software has been used in a range of aircraft from two seat STOL aircraft to electric vertical takeoff and landing (eVTOL) aircraft.
