Abstract:
Objective:To compare the effects of experiencing the black hole illusion in 2 training scenarios.Methods:Sixteen pilots, who were randomly divided into no reference group and finite reference group (8 pilots in each group) by visible substance in approaching, experienced black hole illusion through approaching flight under dark condition on the spatial disorientation simulator. No reference group conducted black hole approaching flight under complete dark environment besides the runway lights while the finite reference group had a day sight to runway before entering such complete dark approaching. The success rate of landing, the angle of departure from the runway and the angle of departure from the glide line of the two groups of pilots were statistically compared and analyzed.Results:There were 2 successful landings in no reference group, and 6 successful landings in finite reference group. There was a statistically significant difference in the success rates of landing between no reference group and finite reference group ( P>0.05). The deviation angle of the aircraft from the runway in no reference group was significantly higher than that in finite reference group ( t=4.04, P=0.005). The deviation angle of the aircraft from the glide line in no reference group was greater than that in finite reference group, and the difference was statistically significant ( t=3.64, P=0.008). Conclusions:The reference plays a key role in black hole approaching. The less reference in simulator training scenario the stronger black hole illusion pilot perceived and influence on operation. It is suggested that flying by instrument would be critical to overcome black hole illusion.
