Note that I am not a CFI. I have my private, and I was heavy into flight sims prior to beginning my training. There are advantages and disadvantages to becoming flight sim proficient prior to taking flight lessons. For those, like myself, who approach a flight sim as more than a game, one of the best things is that you have a sense of procedures and terminology before ever stepping in a real cockpit. You know and can use instruments with ease. However, one of the disadvantages is that you know and can use instruments without appreciating the necessity of looking out the window for traffic. Also, bad habits learned on a flight sim may be hard to break in the real airplane.
Yet, even with my license, I do find the flight sim to be a useful tool. I use it to keep proficient when I’m away at school and don’t have as many oppotunities to fly in reality.
As far as the turn to final - it’s a lot easier in real life than on the flight sim, and once you do it in real life it becomes a lot easier on the flight sim.
