A impaired operator detection system detects impairment of an operator of any equipment, system, or vehicle which requires continuous compensatory tracking, or nulling, of course deviation error. Operator control actions (2, 4) are characterized as a complex sine wave (8) and then a power spectrum array, (PSA), analysis (10) is used to characterize this control action data. Statistical techniques (12) are used to predict the level of operator alertness by comparing the analysis results of the operator's recent control actions to empirical power spectrum array, (PSA), analysis data (14) indicative of an unimpaired operator.
