Last time I saw a F4 simulator at Coningsby the 'cockpit' was 'white washed' with no view outside whatsoever!
So was the Lightning sim.
I have MSFS on my PC. Occasionally I''l use it to practise some VOR intersections or such but as an actual sim to replicate flying it's useless. Great for procedures, don't have a problem with it for stuff like that but it ain't like flying a real aircraft, how can it be, it's a few quid and it sits on a home PC.
We have it at my club, three screens, all the yokes pedals and levers and no one uses it.
