>>1850940Excessive reliance on instrumentation, sight picture assumption, and expectation bias when it comes to situations to name a few. You get used to practicing a procedure in the sim but the sim fails to accurately represent the maneuver in the aircraft. All of that changes when you get in the plane.
It is a kinesthetic and dynamic experience, and while procedural development and reinforcement is great in the sim, there is just a lot more going on that is eliminated or simplified in a sim. Fast, abnormal, or unfamiliar radio calls and ATC instructions, atmospheric factors, aircraft subtleties (system management, performance variations, control input/technique variations, abnormalities), human factors (pilot condition, response time, workload and task management, kinesthetic learning and skill development, psychological and physiological response to stimuli), and other stuff just aren’t accurately modeled or cannot be simulated in any practical sense.
If you have the spare change and time go for it and get a sim, I had a ball when I did it long ago. Sims are a lot better too, and are a lot more immersive. But do take it for what it’s worth, procedural introduction and entertainment.
