I was just thinking how to follow the official approach procedures, e.g. with racetrack on default ATC that, by default, vectors an aircraft to ILS path always from "straight in". Did anyone tried to ignore orders asking to perform some turning? Will the ATC cancel our IFR plan in such case? Of course, I am going to follow the commands about the altitude but I would be sometimes happy to land more like the real pilots do.I know that I might buy some 3rd party ATC products, but before that I would be happy to do some training with the default ATC.

The ATC won't cancel your flight plan, it only does unless you fail to acknowledge an instruction. You don't have to follow the altitude instructions either. ATC will repeat every 2 minutes until you comply.Although the stock ATC has flaws, I've learned to "work" with it and I'm quite happy with it. To answer your question, when the ATC hands you off to approach, acknowlegde it but don't contact the next station. Fly your approach and only contact ATC when you're around 20-30NM from your destination. ATC will clear you to the active runway and hand you off to the tower. It works 95% of the time for me.The default ATC menu might also have a transition that you might want to fly per your published approach. Select it and ask for it as well.The best alternative however, is to get ADE9 and re-write the approaches, that way AI will fly them as well.Hope this helpsEDIT: I found this old thread, it may be of helphttp://forums1.avsim.net/index.php?showtopic=242908&hl

If you want to do your own thing with default FS ATC without them canceling your IFR plan, is to simply not bother contacting the next frequency when they give you a new frequency to tune to, that way you won't have them constantly asking you to respond, so naturally, they won't cancel your plan. When you want to resume ATC-controlled flight, contact ATC and you'll be passed to whatever is the appropriate frequency for wherever you are on your flight. Doing that will let you make your own approach.That's not realistic, but it is a way around things if you don't want to use a third party ATC program.Al
