Simfly
I fly the 757/767/200-300. I also have 767 PIC.
Verdict: Absolutely first class.
I must admit to only having given it a few hours of my time. Too much like work really but so far everything seems to be very faithful to the real thing.
A few libertys have been taken with the location of some controls but this has been done to improve user friendliness.
Also the fix page in the FMC doesn't seem to work.
Haven't tried too many failure scenarios but will give it a bit of stick prior to my next visit to the real sim.
Did try a double engine flameout and it functioned pretty well but it took me ages to find out how to stow the RAT. Take an engineer with you.
Autothrottles a bit duff
I wish I'd had access to it when I was converting on the type.
CaptainSquelch and Jetdriver. Don't knock it till you've tried it. I really think you would be impressed.
Overall 10 out of 10.
