I was given a sim ride for my first fixed wing job after 7 years flying helicopters and light aircraft. I had a heli IR but that was of little use on the sim ride. I could have done much better if I had read and understood fully the sim brief I was sent. In particular power settings and pitch attitude. The sim is a mathematical model, so seat of the pants stuff doesn't really apply. Fly the numbers you will be fine. Communication with your partner is also important. Use the auto pilot if you are able and try to relax.
All easily said! Flying heavy jets for 2 years now and still learning!
All the best!
Cheers
