Wrong.
The 777 and 787 are FBW only, and some of the older designs such as the 767, 747-8 use FBW to a degree.
The 787 is full electric meaning no bleed air or hydraulic pumps to run the flight controls which means they fly anywhere near a thunderstorm they can become a 175+ ton lawn dart.
FAR 25.1316(c)(7)... while I don’t have full confidence in the type certification process after the 787 battery fiasco, the requirement for the manufacturer to prove that exposure to an extreme lightning environment is there. Do you know of any accidents that have proven to be the result of loss of primary flight controls due to lightning strike (military or civilian)? Any cases of temporary loss of primary flight controls due to the same? I can’t say that I follow accident investigations or incident reports too closely, but I’ve never heard of such an event. Lightning strikes are fairly common events and I’d be shocked if the 787 (much less all the FBW airbus in operation) have not incurred multiple strikes by now.
