[Avionics Today 04-23-2015] Presagis, a provider of commercial modeling, simulation and embedded software, has acquired intellectual property from Flexible Software Solutions that will allow the company to support the full life cycle of safety-critical aircraft systems software development.

"This acquisition is an important step forward in delivering our vision to enable close collaboration between airframe and avionics systems manufacturers at every stage of the development process, from design to delivery," said Stephane Blondin, head of product management and marketing.

Through the acquisition, Presagis will gain two products related to the User Application Accelerator (UA2) and UA Emulator (UAM), from Flexible Software Solutions. The UA2 software allows User Application (UA) developers to simplify the process of interfacing ARINC 661 aircraft system software to Cockpit Display Systems (CDS). UA2 hides the complexity of the communication protocol by automatically generating all necessary software code allowing developers to focus on the system being developed rather than the complexity of ARINC 661.

By decoupling CDS and UA software through an industry standard protocol, ARINC 661 offers avionics and airframe manufacturers a modular, portable and interoperable approach to cockpit software design. This promotes reusability of CDS widgets across aircrafts and offers a way to upgrade and evolve glass cockpits over time.
