1. Chair fly
2. Know the profiles, callouts, and procedures stone cold. I put them on the iPod and listen to them ad nausem 1 week prior to sim-time.
3. Ask the sim jockeys for power/pitch settings. It works for them, it will work for everyone.
There are no surprises in the sim . . . unlike the real airplane. It's all a head game anyway . . . easy to say, hard to make your head believe sometimes. The more of these you do over your career, the more they become routine, just like anything else.
