[Avionics Today 10-04-2016] LDRA, a company that specializes in standards compliance, automated software verification, source code analysis and test tools, and Konatus, LDRA’s engineering partner in Brazil, unveiled the details of the flight system control safety testing methodology that contributed to the launch of Embraer’s next-generation E2 jet aircraft months ahead of schedule.
The Konatus engineering team deployed LDRA’s comprehensive safety verification tool suite to optimize testing, mitigate certification risks and dramatically reduce Embraer’s safety verification schedule for the E2 aircraft maiden flight in May 2016.
“The LDRA and Konatus teams and technology were instrumental in helping us with the large volume of test cases needed to ensure the aircraft’s safety prior to the E2’s first flight,” said Marcos Gritti, manager of flight control systems at Embraer.
LDRA and Konatus began working with Embraer in early 2013 to establish a safety standards and compliance methodology for the E2 aircraft family using the LDRA tool suite for software requirements, team task management, flight control system safety assessment, verification and validation. The E2 is Embraer’s first civilian aircraft project that implements fly-by-wire software fully developed internally and tested with the LDRA tool suite for certification for DO-178C — the primary standard for commercial avionics software development.
