Abstract： Objective To explore effectiveness of improving the abilities of instrument visual spatial orientation (IVSO) training for high performance fighter pilots. Methods An IVSO training device was developed.Based on the principles of computer graphics and characteristics of cognition,4 kinds of instrument flight condition patterns were adopted as training profiles.Eleven pilots were trained along these four training profiles for five times,include recognizing and flying by instrument and head-up display respectively in complicated flight sortie or with interference.The reaction time,rate of correct operation,deviation angle of attitude and the adjunctive task completion rate were recorded and compared. Results In pre-and post-IVSO training,the reaction times got with instrument and head-up display in complicated flight sortie were (1.42±0.24)s vs.(0.99±0.13)s and(1.54±0.29)s vs.(1.05±0.12)s respectively while the rates of correct operations were 53.91%±9.12%vs.90.00%±5.88%and 73.09%±12.02%vs.89.18%±6.10% respectively.Deviation angles of roll and pitch in maintaining flight attitude by instrument training were 3.25°±0.60°vs.2.07°±0.25°and 2.41°±0.63°vs.1.87°±0.30°respectively,comparing to 3.08°±1.03°vs.2.06°±0.35°and 2.84°±0.67°vs.1.99°±0.20°in attitude maintenance by head-up display.Adjunctive task correct rates with believing instrument and head-up display were 63.90%±11.15%vs.88.27%±10.23%and 59.73%±12.81%vs.82.09%±9.62% respectively.All differences between pre-and post-IVSO trainings are statistically significant (t=2.47 to 11.03,P<0.01 or P<0.05). Conclusions The adopted instrument flight training can remarkably improve pilot's IVSO abilities.
