The relationships between subsystem design characteristics, training cost, training difficulty, and job performance were investigated for avionics subsystems. A list of relevant design characteristics was established. Functional loops were selected from 10 subsystems representing navigation, flight control, communications, and fire control subsystems. Performance tests for each of the 30 functional loops were identified or constructed. Ten AF students performed each of the tests. Time and errors were recorded for using equipment and reading technical orders T.O.s. Both stepwise regressions and factor analysis were used to derive equations to predict performance time, training time, T.O. time, errors, and training equipment cost from equipment design characteristics, personnel characteristics, and environmental variables. Multiple correlation coefficients were 0.88 or greater. Factors of length of checkout procedure, equipment complexity, difficulty of checkout steps, nonautomatic checkout, diagnostic information, and clarity of information were identified. Applications of these equations should, for the present, be made cautiously, particularly if any of the input data fall outside the ranges which entered into derivation of the equations.
