Very sad but at that time of night most would be startled. But again it shows how modern cockpits & automation has eroded basic flight skills. Something I found coming from a more basic type where a good instrument scan was natural. To tunnel vision as everything you need is on the PFD. Methinks in the past a artificial horizon failure woul just cause a que? Moment as your instrument scan (more like a total look) would immediately alert you to it not being right. I realise the pfd saves the big scan but think it is a human brain thing. More human research should have been done before creating complex displays.
