Well this sounds like a bunch of guys needing to lean on a bunch of cockpit gear..
I can't think of any jet aircraft who's gear isn't up to the task...I mean the screens aren't going blank,
Well this sounds like a post from a guy who hasnt spent 5 years with a 680.
Blank PFD's on 4 occasions, all un-recreateable, all fixed by themselves when airborne.
All described by Honeywell as a "Proton Event"......which means they haven't a clue incidentally.
and if the direct to function on your FMS gives you bug for the A/P to fly...what the heck is the problem.
The problem is we've just spent 18US on something which should offer a bit more functionality than a KNS80 - dont you agree? or are you one of these guys who's G550's VNAV button is covered in dust and you cant read the letters on the HDG and V/S buttons?
