- WalterBright 5y agoOf course, but the specifications are normally written by Boeing, and the implementation is outsourced. The reason is the system as a whole has to function, meaning the spec has to be written by the team that has knowledge of the whole system. MCAS interfaces with quite a few other systems on the airplane.
- _ph_ 5y agoEven a good team can convince itself, that it is right. It would have added a "second set of eyes", if the implementors of MCAS had their own expertise in aviation. No guarantee, but a chance of spotting the problems with the spec.
