During 2006, a team of 20 CS co-workers together with Turbomeca teams ensured conformity with safety and quality constraints (DO-178B and ISO 9001). At stake was the success of different software releases, leading to certification planned for the year 2007, with a maiden flight scheduled for mid-April 2007. Additionally, as part of Turbomeca's modernization programs for its first-generation systems, CS was chosen to develop software for future metering-concept technologies, based on automatic code generation, and specifically meeting the requirements of Turbomeca in terms of lead times and costs.
