Skills such as flying holding patterns are taught in planes or simulators. An alternative method is to use computer-assisted instruction (CAI) which emphasizes training requirements rather than physical fidelity. Such a program was written and evaluated. Traditional groundschool methods were compared with the CAI method. All subjects completed a training sequence in a ground-trainer. Those taught by computer performed better on all measures, attaining criterion quicker and with significantly fewer critical errors. Results indicate that CAI offers an inexpensive and effective alternative to the costly trainers currently in use.
