The cockpit was not designed pilot friendly and it flys like $hit. Based on what people have told me the X sucks too.
Coming from an A320, all of these corporate cockpits are too small and uncomfortable. I got hired into the X, and yes the cockpit is small, but you get used to it. I have heard that the Hawker is better. As far as flying the X, I think its flies fine. Since most of the flying is done with the autopilot on, I think it flies just fine. I have seen guys land it, lets just say "different than me". Some of the guys "drive it onto the runway" without straightening the nose before landing (using rudder). I like to flare and use the rudder to land with the nose pointed down the runway.
It is fast. .90 is normal cruise. .92 after you burn off some fuel.
Pax like the speed. The typical flight ( if there is such a thing) has no more than 3 pax. Very comfortable. I have had 8 pax a few times, it does get a little tight back there.....but doable.
The typical NJ week ( again, there is no such thing) can be transcons day after day, or it can be bouncing around Florida for a day or two. I find myself in SJC, LAX, MIA, DAL or ASE, EGL. Not so much FAR or FSD....although, I did go into 2 uncontolled airports last week.
