PM and PF should glance at their PFD regularly.
Correct; but as was touched on in another topic, this glance is often only to see of the FD is centred, which with A/P in CMD it will be. Let's remove the FD when A/P is in CMD. This will force a better scan
Such pilots perhaps do not develop the vital need to monitor because the modern jets' automatics rarely go wrong, whereas those of us who flew aircraft with crude and unreliable 'automatics' (or no automatics) quickly developed a good regular scan to check that all was well, or to do something about it if it wasn't.
This ties in with automation dependancy.
Let's make a/c and flight-decks where things go wrong more often and the back-up system has to be selected manually if the re-set function doesn't work. Ha! Back to the future. Yippee said the ex-FE.
