Simulators
Simulators are a T&D delivery system comprised of devices or programs that replicate actual job demands. The devices range from simple paper mock-ups of mechanical devices to computerized simulations of total environments. Training-and-development specialists
may use simulated sales counters, automobiles, and airplanes. Although simulator training may be less valuable than on-the-job training for some purposes, it has certain advantages. A prime example is the training of airline pilots in a simulator; simulated crashes do not
cost lives or deplete the firms fleet of jets.
