somebody turning on 'rogue system' remotely?
The Ethiopian investigation has focused on the anti-stall system, which in the case of the Lion Air crash exerted more and more force until the crew lost control. The software had kicked in on the same aircraft the day before, when an off-duty pilot riding in the cockpit was able to save the plane by helping to cut the power to the rogue system.
The feature, known as the Maneuvering Characteristics Augmentation System, was designed to keep the Max from climbing too steeply and stalling. The U.S. Transportation Department has begun an inquiry into how it was approved as part of the Maxโs certification in 2017, while the Justice Department is using a grand jury to gather information.
Officials from the two departments and the Federal Bureau of Investigation began digging into a range of matters related to MCAS within weeks of the Lion Air loss, Bloomberg has reported.
