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, and if the direct to function on your FMS gives you bug for the A/P to fly...what the heck is the problem.
That said...I have had mixed experiences from Flightsafety and much prefer Simuflite on Cessna gear.
