Well there are quite a few points with the sim and also what plane you use for the training.
Some FNPT II schools you only get a small amount of flying time. But you do have a very sexy fun machine to play in.
But its more to do with what happens after you have passed your IR which all schools can get you through no matter what sim they use.
Under JAR ops to fly single pilot IFR you need 700 hours, 400 pic, 40 Multi and 100 IFR.
So what you really need to do is work out a method so that after you have finished training you have as much of those hours logged as possible so you can work air taxi if it becomes an option.
You don't want to have to pay to hour build the multi time so you want to get 40 hours multi time by the time you have finished your IR. 5 hours for MEP and say 2 for the IR skills test gives 33 hours needed somehow in the twin. So its well worth upgrading any single IFR training to twin just to get the hours in the book. I think it cost me an extra 300 quid to upgrade my single time to twin on my IR.
So if you want to keep the option open of air taxi work you need to get that twin time in your book and a max hours discount FNPT II course isn't going to help you. And after you have your IR even if the wx is CAVOK book out IFR until you have the 100hours IFR time.
