Re: Designs of aircraft control systems have been, at times, cringe-worthy
'What's annoying is that any informed layman could have written down some common sense requirements to ensure that such systems were better designed.'
With hindsight yes, the problem is predicting the unlikely things people will do in an emergency situation before that happens for the first time.
It's also notable that in the China Airlines example you give, Airbus had a fix but the airline had yet to install it.
