Optimal operator performance is critical for the functioning of many systems and especially for systems as complex as modern aircraft. However, direct measurements of operator performance to evaluate aviation systems and related subsystems can be difficult to obtain. Instead, human performance is usually inferred by observing its effects on the aircraft. To further aid in measuring performance, the operator is sometimes asked to provide a subjective rating of individual tasks. While subjective rating scales can provide valuable information, their interpretation can be limited by such factors as previous experience, selective memory, and expectations of the operators. Physiological data, however, can provide more direct measures of the internal state of the operator and, as such, can be a powerful tool for the evaluation of aviation systems.
