The visual performance of helicopter pilots during simulated extended operations was examined in terms of methodological issues and statistical analysis. Visual performance data collected, but not analysed, during a simulated extended operations study by investigators at the U.S. Army Aeromedical Research Laboratory USAARL, Ft. Rucker, Alabama, served as the data base. The dependent variables associated with visual performance during IFR were factor analysed and it was concluded that the data could be largely accounted for by two orthogonal factors measures of the relative importance of an instrument during a flight segment and measures of the central tendency of the fixation times. Several findings reported in the USSARL Report No. 78-6 were replicated in this study but the three zonecost factor theory offered in that report was not supported empirically. Statistical analyses revealed several differences in the use of the instruments as a function of flight maneuver instrument take-off, cruise flight, and instrument landing, but no differences that could be attributed to the effects of fatigue.
