To maintain a Boeing Dreamliner flying, reboot as soon as each 248 days
The 787 Dreamliner has been plagued with battery woes since its early days, to the purpose the place the Federal Aviation Administration stored it from flying the skies up to now. And whereas these technical difficulties are apparently taken care of, Boeing’s flagship airliner might be on the best way to extra hassle quickly. Based on the FAA, there is a software program bug within the 787 Dreamliner that may trigger its electrical system to fail and, in consequence, result in “lack of management” of the aircraft. However why? The FAA says that is triggered by the plane’s electrical turbines, which might give out if they’ve been powered on constantly for over eight months.
248 days == 2^31 100ths of a second. even in 2015, our airplanes have integer overflow bugs https://t.co/6Z8d4y9gjM

“A Mannequin 787 airplane that has been powered constantly for 248 days can lose all alternating present electrical energy because of the generator management models concurrently going into failsafe mode,” the FAA stated in a press release warning of the flaw. “We’re issuing this AD to stop lack of all AC electrical energy, which might end in lack of management of the airplane.” Boeing, for its half, is conscious of the issue and has reset the facility on 787 Dreamliners at present in service. Most significantly, the corporate’s already engaged on an replace that may patch the software program vulnerability — although there is no phrase on when its jets will obtain it.
