Latest 737 Max fault that alarmed test pilots rooted in software

As US govt test pilots ran through dozens of flight scenarios on the Boeing 737 Max in recent weeks, a potential failure got their attention. The plane’s flight computer tried to push the aircraft’s nose down repeatedly during a simulator run, prompted by a stream of erroneous flight data. The FAA pilot concluded commercial pilots might not have time to react and avoid a tragedy in a real plane. That flaw -- the latest discovered on the family of jets involved in 2 fatal crashes since October triggered by a different failure that pushed their noses down -- was revealed by FAA last month. It threw new uncertainty on the return to flight of the company’s best-selling model and sent its engineers scrambling for a fix. “We are confident that is a software update, not a hardware update,” Boeing CE Dennis Muilenburg said Wednesday. <br/>
