That's not true for Boeing aircraft. They are designed to be flyable manually, unlike Airbuses, which are fly by wire.

- TylerE 7y agoThe 777, 787, 747-8, and 737 Max are all fly by wire.
- inamberclad 7y agoThe Max is not fly by wire, that's the problem. It's a hydraulic/mechanical control. That's why pilots aren't able to pull it out of dives or re-trim it, the aerodynamic forces are too much for the crew to fight against.
- Animats 7y agoRight. If this was a fly by wire aircraft, it would have to have triple or quadruple redundant control systems and redundant air data sensors. But because the auto-trim system wasn't considered primary flight control, it didn't get evaluated like a fly by wire system. Auto-trim has been around for years, and failures are usually more annoying than serious. But the 737 MAX's auto-trim had far too much control authority, and was being used to compensate for bad handling characteristics, making it a flight critical system.
- usrusr 7y agoAnd if they hadn't opted for secrecy, properly put it in the manual instead of hoping that the outcome of bad sensor readings would appear like that of a fried switch, someone might have realized what a perfect trap they had built while writing "engage trim cut-out, then work the manual trim wheel until you regain control or hit the ground, whatever comes first".
- ulfw 7y agoNeither is the 747-8. Half of his examples were made up.
- TylerE 7y agoNot fully, but spoilers and ailerons in the -8 are FBW.
- ummonk 7y agoThe other three are but the 737 Max is most definitely not fly by wire.
