The problems regarding simulators are the costs and return on capital investment. For large aircraft, the manufacturers will build the simulator at the same time as they produce the aircraft. As soon as the aircraft is delivered, the simulators are available. With regard to small helicopters, however, the simulator costs more than the helicopter does. For example, a small piston helicopter costs $400,000 and the simulator might cost $1 million or $2 million.
