The US air safety authority has issued a warning and maintenance
order over a software bug that causes a complete electric shutdown of
Boeing’s 787 and potentially “loss of control” of the aircraft.
In the latest of a long line of problems plaguing Boeing’s 787 Dreamliner, which saw the company’s fleet grounded over battery issues and concerns raised over possible hacking vulnerabilities, the new software bug was found in plane’s generator-control units.
The plane’s electrical generators fall into a failsafe mode if kept
continuously powered on for 248 days. The 787 has four such main
generator-control units that, if powered on at the same time, could fail
simultaneously and cause a complete electrical shutdown.
