As a "victim" of sim sessions at Flight Safety, SimCom, and CAE SimuFlite, I think there is a mindset that emerges, mostly inadvertently, along the lines of "What must I do to get through this sim session?" Of course we all want to do well in the sim, but this line of thinking tends to disconnect what happens in the sim from the real world. IMO, important to work at keeping a global view of training and how it relates to flying the acft in real day-to-day conditions.
