Reports by A.V. Patel and Co-Researchers Describe Recent Advances in Algorithms (Clearance of Flight-Control-System Software with Hardware-in-Loop Test Platform)

By a News Reporter-Staff News Editor at Computer Weekly News -- Investigators publish new report on Algorithms. According to news reporting from Bangalore, India, by VerticalNews journalists, research stated, "The Indian Light Combat Aircraft has flown more than 2000 flights, including trainer and naval variants, without encountering any major faults in the flight safety-critical fly-by-wire control software. This is partly due to the stringent quality control and rigorous testing of the control-law and air-data-system algorithms carried out on various ground platforms before flight."

The news correspondents obtained a quote from the research, "One of these ground test platforms is the hardware-in-loop test platform (Iron Bird). The processing of tolerance bounds to define the pass/fail criteria is an algorithmic development. It guarantees the correctness of the modules, if the set of inputs generates a set of outputs within processed tolerance bounds. This paper presents the philosophy behind the design of test cases and the tools developed to evaluate the control-law and air-data-system modules on the Iron Bird platform, and the procedure to clear the test results. The computation of tolerance bounds and algorithms for their processing have been evolved over a period based on several criteria, testers' experience, and the experience gained during various levels of testing of air-data-system and control-law algorithms."

According to the news reporters, the research concluded: "This process yielded excellent results, and is accepted as a formal clearance methodology for the onboard safety-critical fly-by-wire system software."
