Anyone familiar with the Boeing 787 Dreamliner electrical system? After reading this article: Dreamliner's Nightmare and this quote: I'm not sure what is being referred to. I suspect this is just another example of poor aviation reporting by people not familiar with aviation. The airplanes I know about usually use electrical generators and/or hydraulic pumps powered by the engines to run the controls and devices like landing gear retraction/extension. Some aircraft (like Airbus) use primarily engine driven generators to handle electric and to run electric hydraulic pumps. This Boeing article says there are engine driven generators, so I think the issue with the 787 is associated with it's electrical buses located in the electronics bay. The emergency landing described in the Newsweek article where the crew was totally dependent on the RAT- Ram Air Turbine to provide the soul and limited source of electrical power is not a good thing.
