An analysis is presented of aircraft pilot eye movement data obtained in the past by other investigators from piloted flight tests. This includes a comprehensive account and reanalysis of the data contained in several reports, by different investigators, and it suggests some features of a useful systems model which should be compatible with i.e., explain all, or nearly all, of these data. A review is presented of key contributions to the literature, primarily of Fitts and Senders work. Pilots eye fixation frequency measurements are first discussed with respect to four possible variables on which they may depend display-control closed-loop bandwidth, flight maneuvers, instrument arrangement, and the redundancy of information. Pilots eye fixation dwell times are then discussed with respect to a quantized time interval which appears in certain experiments, and the purpose for and type of sampled signal reconstruction which may be performed by the pilot. An approximate method suggested by Senders for calculating paired-display fixation link values is applied to one of the extant cases not investigated by him. Some experiments are suggested to resolve questions, validate models and fill voids in existing results.
