Abstract: A simulator system adaptable to an actual craft or existing simulator is disclosed. The system comprises computer hardware and software capable of simulation, combinations of simulations and networked simulations. Computer inputs come from sensors attached on or near control and operation members. Computer output is sent to overlay displays and other components. Visual, audio and motion cuing systems are added to increase realism where appropriate to the simulation. All equipment may be quickly and easily installed or removed so as to make maximum use of an otherwise inoperative craft or allow for diversity and upgrading of existing simulators. By the use of computer program modifications and component construction, the system may be used to simulate a wide variety of craft, including air, ground, naval and space craft.
