Investigation of occurrence and influencing factors of flight illusions among army helicopter pilots in cold regions
To investigate the occurrence of flight illusions and explore its influencing factors and countermeasures in army aviators in cold regions.
Methods
2
Comprehensive Flight Illusion Scale was applied to investigate flight illusions
related influencing factors and countermeasures among 74 army aviators in cold regions from December 2022 to February 2023. SPSS 22.0 statistics was used for statistical analysis to compare the differences among variables and identify the influencing factors of flight illusions.
Results
2
For the 74 issued questionnaires
all of them were retrieved validly
with a rate of 100%. The incidence rate of flight illusions was 32.43%. There was a statistical difference between flight time and the occurrence of flight illusions (
P
<
0.05). There were 3 types of flight illusions with higher incidences in cold regions
that is distance illusion (20.27%)
tilt illusion (18.92%) and relative position illusion (16.22%). The 3 flight illusions with relatively lower incidences were detachment phenomenon (4.05%)
rotational illusion (4.05%)
and inverted flight illusion (2.70%). After occurrence of illusions
66.67% of the aviators experienced symptoms such as tension
"hard-to-move lever" headache
dizziness and post-flight insomnia. Almost all of the aviators were of fully awareness and acceptance of the active approaches to dealing with flight illusions
but still 50% of them believed that passive waiting intervention measures could be used. The results of statistical analysis on related influencing factors indicated that statistical differences were observed in all the listed items except flight subject with the occurrence of flight illusions (
P
<
0.05).
Conclusion
2
During short period flight in cold regions in winter
army aviators experience obvious psychological and physiological reactions after occurrence of flight illusions
and their anxiety and fatigue state
external climate and landform environment
and cabin interface and flight parameters are all related to the occurrence.
