I personally don't believe that busting at Simuflite would make someone a 'MOW RON'. However I have seen a couple of people fail over the many years I have been going there. Usually it is someone who was moving far beyond their current capabilities. One case in point that I remember was a pilot in the Lear 20 program. The biggest thing that this pilot had flown before was a Seneca. Class work I was told was fine, but the sim was something else. This pilot was way beyond their capabilities. A little more experience and more time, it would have been a different story. Simuflite, like FSI, doesn't want you to fail. It reflects badly on them. You do have to study and know the material. You have to put in an effort. It is not beer and party time.
That said, a couple of observations. One, this is a good time to network. Spread out your roots, met new people and develop contacts. If you don't already, get some business cards. The reading room and cafateria are good places to meet others. Next, Simuflite, like FSI, have pilot enrichment class. When ever I am there, I take as many as I can. You are investing in your career. Make as good as an investment as you can.
Have fun.
