Re: Lack of systems thinking
"Surely the underlying issue is a lack of whole systems thinking."
Yup. This in spades. One of the things that always stood out is how badly disconnected (and disorganised and just plain dis-ergonomic) most flight deck systems are. There are a lot of things that "should" be automated but simply aren't (because noone thought about it, or "it's too hard") or where having various systems talk to each other would save a lot of hassle.
The L1101 and the Tristar both proved that things could be done a lot better, but "better" doesn't always sell well.
