Boeing To Make Key Change in 737 MAX Cockpit Software
Tuesday March 12, 2019. 08:33 PM , from Slashdot
Boeing is making an extensive change to the flight-control system in the 737 MAX aircraft implicated in October's Lion Air crash in Indonesia, going beyond what many industry officials familiar with the discussions had anticipated. From a report: The change was in the works before a second plane of the same make crashed in Africa last weekend -- and comes as world-wide unease about the 737 MAX's safety grows. The change would mark a major shift from how Boeing originally designed a stall-prevention feature in the aircraft, which were first delivered to airlines in 2017. U.S. aviation regulators are expected to mandate the change by the end of April.
Boeing publicly released details about the planned 737 MAX software update late Monday [Editor's note: the link may be paywalled; alternative source]. A company spokesman confirmed the update would use multiple sensors, or data feeds, in MAX's stall-prevention system -- instead of the current reliance on a single sensor. The change was prompted by preliminary results from the Indonesian crash investigation indicating that erroneous data from a single sensor, which measures the angle of the plane's nose, caused the stall-prevention system to misfire. Then, a series of events put the aircraft into a dangerous dive. Read more of this story at Slashdot.
