[The study of illusion in flight on flight pilots].

OBJECTIVE

To observe the characteristics of illusion in flight in fighter pilots.

METHOD: A survey about illusion in flight was performed in 81 pilots who were under physical examination for modification to equipment of high performance aircraft.

RESULT: 1. Among 81 pilots, there were history of illusion in flight in 91.4% (74/81) cases. There were history of inclination illusion in 74 cases, rotation illusion in 1 case, inversion illusion in 1 case and pitch illusion in 1 case. 2. Among the 74 cases, 85.1% (63/74) claim relations with flying subjects, 81.1% (60/74) with distribution of attention, 74.3% (55/74) with light, 73.0% (54/74) with distribution of cloud layer, 71.6% (53/74) with visibility, 67.6%(50/74) with fatigue, 54.1% (40/74) with suspension of flying and 2.7%(2/74) with other factors. When illusion in flight appeared, 70 cases could easily overcome it, 4 cases felt a little difficult, but all 74 cases did not lead aircraft accident or potential accident.

CONCLUSION

Instructions in health about illusion in flight have made a considerably positive achievement in airman troops, but it must be continually paid more attention, and meanwhile, the space orientation system of aircraft must be improved.
