Thanks very much for both of the replies, but just to update the situation, today's email suggests that there was a slight admin glitch, and that the sim ride will actually be done in the -200.
The -200 has sticky old throttle quadrants, the -400 is much newer so much easier to set the right power. Both in setting power and looking at indications.
B53 what you say makes perfect sense, but remember from our side of the fence it looks a bit different. Typical candidate's perception prior to 2nd interview...
Choice A: Critically important assessed simulator ride in a sim you have 1 hour's experience in.
Choice B: Critically important assessed simulator ride in a sim you have seen pictures of on the Boeing site.
Perhaps slightly overstating the facts, but i'm sure you are with me! Assuming that all goes well however, then that's a different matter. Wall to wall glass and lighter on the controls gets my vote for sure!
