In a bizarre situation, the Boeing Dreamliner has a strange software bug! This bug in the 787 Dreamliner leads to failure of its electrical system which causes “loss of control” of the plane. The plane’s electrical generators could fail completely if they have been continuously powered on for over eight months. In other words, the electrical power needs to be shut down periodically to obviate the manifestation of the software bug which will lead to loss of control.Press 'Restart' or Pilots can lose all control of Dreamliner 787! #Codebug #technology Click To Tweet
To be fair, this error has happened in the laboratory and no airplane has ever experienced it.
The Federal Aviation Administration said on Thursday that Boeing found during laboratory testing that the plane’s power control units could shut down power generators if they were powered without interruption for 248 days, or about eight months. The findings were published in an airworthiness directive.
Boeing said the problem had occurred only in lab simulation and no airplane had experienced it. Boeing said that powering the airplane down would eliminate the risk that all power generators would shut down at the same time.
As serendipitous as this is, authorities cannot let it happen on a real flight. So its good that it came out in the lab.
248 days == 2^31 100ths of a second. even in 2015, our airplanes have integer overflow bugs https://t.co/6Z8d4y9gjM

The software update to cure this bug will be ready by the 4th quarter this year. Until then, do what we all do with our computers – RESTART – and it will be fine!
