A piloted flight simulation aiming at quantifying visibility effect on helicopter piloting was carried out. The flight simulation was conducted in the way of varying the visibility of the visual scene and the stability of the aircraft, respectively, so as to determine a critical value of the stability with which the pilot can barely control the aircraft. Eye fixation points data of the pilots were obtained in each visibility condition. The flight simulation results enabled direct evaluation of visibility effects upon pilot control performance in terms of helicopter stability. Some considerations of effectiveness of stability augmentation systems and display systems in low visibility condition are also described in this paper.
