GeeWhizz,
Probably a bit off topic so I'll leave it at this.
I totally agree with you on all of those points. I should have pointed out that I was referring to the earlier stages of training in my comment. Yes, FS is better regarded in terms of NAV work and I've even heard instructors making favourable comments in this regard.
Of course the visual picture of the landscape will be awful, as will any kind of angle perception for circuit work and landings I.e. the actual flying of the aeroplane. This is where not to use it.
Agree, even with the "best" VFR scenery and addons this is where it falls down really badly (pardon the pun). I have made a few disastrous flares and "hold offs" earlier in my training because I was practicing on FS thinking I was getting ahead. I was wrong and I don't recommend it.
I still fly on FS regularly because I thoroughly enjoy it, but I am now much more aware ofs limitations.
