Most of the stuff is crutches for people that need the automation and SA to lean on or having new toys to play with.
What kills me is that I saw a flight dept crumble after the pilot put the plane down for like 4 months to UPGRADE from an XLS to a UNS1....
or Airlines that could have paid the pilots, but instead upgraded the whole fleet, then 4 years later the company is going banko..
or how about guys that pay millions for a single engine turbine to get the avionics, new leather....and still stick it in the water...when a twin for half the price, but older avionics, would have saved the day.
Don't even get me started on HUDs, TCAS II vs I....
