I would not underestimate the value of simulator training in the high tech world of aviation. It can save many hours in learning emergency procedures, normal procedures and limitations. I was in the first test class to receive the complete syllabus of CH-47 transition training in the first CH-47 simulator. All training was done in the simulator. My first "hands on" on the real aircraft was a checkride which was exactly the same as the rides given to a control group who flew nothing but the real aircraft. I passed the ride easily and was amazed at my own proficiency in the aircraft. So the simulator can save a good deal of money and even equipment in training up flight crews. Money that can be better spent in other areas such as R&D and procurement.
That isn’t the point. Simulation Training is excellent, but without “hands on” with the real thing, you cannot expect to be considered fluent without actually flying the real thing and then prior to flying on an actual combat mission.
