The computer user refrain of "unplug it and plug it back in again" now applies to Boeing 787s. On Dec. 2, the FAA issued an airworthiness directive that required operators of all Dreamliners to power their aircraft down completely and turn them back on again by Dec. 9. The order came after the FAA said it "received reports" (it didn't say from whom) that if an aircraft was left running for more than 21 days, all three flight control modules (the central control computer and both backups) could simultaneously reset on their own on Day 22.
