Kramer, Arthur, Tham, Mingpo, Konrad, Christopher, Wickens, Christopher D., Lintern, Gavan, Marsh, Roger, Fox, Julianne and Merwin, David (1994): Instrument Scan and Pilot Expertise. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 36-40.

“A study was performed to investigate the correspondence between flight experience and instrument scan strategies. Seventeen student and twenty one instructor pilots flew two instrument flight missions with each mission being composed of eight distinct flight segments. The segments varied in the number of flight parameters that were to be modified including changes in heading, airspeed and altitude as well as double and triple combinations of changes in these parameters. All of the flight segments were flown under strict time constraints. Discriminant analyses were employed to determine the extent to which performance, control and eye scan measures could be used to distinguish among three groups of pilots; student pilots, low time instructors, and high time flight instructors. Performance measures alone were not adequate for discriminating among these groups of pilots, possibly because the maneuvers were relatively simple to fly. However, when both performance measures and eye scan measures were employed discrimination accuracies improved dramatically, ranging from 77% to 98% in the more complex maneuvers. Eye scan measures were also useful in diagnosing deficiencies in student flight strategies such as the over-reliance on a subset of flight instruments.”
