Seated eye positions of personnel in the 1st to 5th percentile range and 95th to 99th percentile range for male stature were examined in six US Army helicopters to determine if their seated eye positions were significantly different from those of instructor pilots. In addition, the zero azimuth, outside-the-cockpit field-of-view of anthropometrically extreme personnel and instructor pilots was measured. In all helicopters surveyed, statistically significant differences were found between the seated eye positions of aviators and that of anthropometrically extreme personnel. Large differences in viewing angles were also observed in all aircraft. However, in the case of personnel in the 1st to 5th percentile range for male stature, the differences were to their advantage. In the case of personnel in the 95th to 99th percentile for male stature, field-of-view was considerably decreased in some aircraft. Further study is needed to determine what effects the reduced field-of-view for tall personnel may have on flying performance. Keywords Field of view, Anthropometry Human factors engineering.
