I am (was) a qualified simulator instructor (Jaguar) with 10,000 real hours in my log book. All types. Simulation has it's place, especially for emergencies etc, but no substitute for the real thing. When I flew fast jets, 15 hours per month (real flying) was considered the minimum. OK, simulation has improved in leaps & bounds in the last 20 years, but will never be a total substitute, one does not crash & burn in a Sim.
