nor do they alleviate the pilot's primary responsibility to look outside while flying.
Look outside when we have all these pretty screens to look at and a radar (or they think it's a radar)...pft why bother? At least this is the mindset I've seen with the handful of guys I've flown with in TAAs. When HUDs are present in GA is when pilots will begin looking outside again.
On the plus side, I flew with a guy a few weeks ago who is a fresh private pilot. He was the first guy under age 50, with private certificate or better, I've flown with that appeared to be comfortable using outside information, instead of instruments, to judge his flight performance. What a pleasure.
