SEATTLE, W (Ben Caxton) — A group of technical experts appointed by federal aviation regulators says pilots won’t need new training on flight simulators to learn how to operate the Boeing plane that was grounded after two deadly crashes involving a new anti-stall system. The group says computer and classroom instruction about new software on the Boeing 737 Max should be adequate for pilots who have flown earlier versions of the 737. Boeing is working on a software fix to the planes’ MCAS anti-stall system. In both an October crash off the coast of Indonesia and a March crash in Ethiopia, a faulty sensor reading triggered MCAS and pushed the plane’s nose down, and pilots were unable to recover. In all, 346 people died in the two crashes.
