Based on the investigation of the present situation of psychological service of military pilots, this paper points out that now the psychological service of pilots is not carried out frequently, and the methods&means are not targeted enough, then analyzes the military pilots' characteristics of psychological stress and their demands for psychological service. It is considered that the psychological service of military pilots should be necessary to strengthen the mechanism construction, cultivate the professional and technical personnel of psychological service, and strengthen the propaganda of psychological knowledge among pilots, highlight the goal and significance of psychological service, in order to achieve the overall service of full coverage and follow-up of the whole process. At the same time, we should pay attention in scientific research, aim at the psychological service needs of pilots, combine with advanced psychological training and evaluation technology, and explore methods of psychological service for pilots with definite purpose and measurable effect.

Objective: To study the psychological tension in electroencephalogram (EEG) of pilots selection in order to provide the evidence for obtaining accurate and reliable results. Methods: A total of 250 senior high school students, aged 17–21 years old, were randomly selected to take part in the physical examination of pilot selection from 2019 to 2020, and were divided into the non-teaching group and the education group (self control), respectively. In the process of EEG examination, the students’ comprehension, cooperation and physiological indicators were evaluated through video demonstration and teaching before examination and heart rate monitoring during examination. Results: Compared with the non-teaching group, the video demonstration helps the participating students to understand the inspection items, get familiar with the inspection process, and get good cooperation. After the beginning of the examination, the heart rate of the education group did not change significantly, and remained at the same level until the end of the examination. There was no significant difference between the heart rate after the examination and the heart rate during the examination (P > 0.05). The heart rate of the uneducated group increased and remained at the same level until the end of the examination, which was significantly different from that of the basal heart rate (P < 0.05). Conclusion: Video education and heart rate detection can effectively improve the students’ understanding and cooperation on the examination items, reduce psychological tension and fear, and enhance the reliability and effectiveness of the selection results.

Cognitive ability evaluation is the main content of pilot psychological selection. Most of the existing cognitive ability assessment is based on a single cognitive ability assessment under normal condition, which does not consider the fluctuation of cognitive ability under the variable operation conditions. In this study, lower body negative pressure bucket was used to simulate accelerated stress, and digital Stroop task was used to evaluate the individual's cognitive control ability. The results showed that the main effect of stimulus information type was significant (F = 22.96, P < 0.01), and the response time to conflict stimulus was significantly greater than that to consistent stimulus (P < 0.05). With the change of operation condition, the fluctuation of cognitive control ability is not completely consistent across subjects. The findings in the current study indicated that digital Stroop task can be applied as an assessment tool of cognitive control ability, and operation condition should be included as a variable in the evaluation of cognitive ability to comprehensively understand the level of individual cognitive ability.

Objective. To study the effects of 8-h simulated flight task on cognitive function and performance of volunteers, and to evaluate the workload of simulated flight. Methods. The subjects started the simulated flight at 9 am and continued to operate for 8 h to complete the simulated flight task. The flight control ability, reaction time, motion time, critical flicker fusion frequency (CFF) and subjective scale were measured. Workload evaluation indicators were detected before, half and after the simulated flight. Results. There were no significant differences in reaction time, motion time, critical flicker fusion frequency and Stanford Sleepiness Scale (SSS) between before, half and after the simulated flight. Compared with preflight, the rating of perceived exertion scale (RPE) scores was significantly increased after 8-h simulated flight. There was no significant difference in the ability of simulated flight control between preflight and postflight. Conclusions. There was no significant effect on the cognitive function and performance of volunteers during the 8-h simulated flight task in the daytime.

Objective To explore the effects of pilot psychological trainings based on different military application purposes, in order to provide evidence for carrying out all-round psychological training in the future. Methods A total of 101 military pilots were trained in three-stage autonomic nervous stability training, and their HRV indexes before and after were compared, then compared these indexes data to the stress protection training to study the different effects. Results 1. After autonomic nervous stability training, the overall level of autonomic neurological function increased, and the balance of sympathetic and parasympathetic functions significantly enhanced; 2. HRV power spectrum adjusted to low frequency; 3. Stress level of pilots after flight mission is higher than their daily lives; 4. After the stress protection training, the stress level of pilots decreased obviously and they were in the state of relaxation, while after autonomic nervous stability training, the stress level of pilots was mobilized to a more suitable working state. Conclusion The psychological training of pilots based on different military application purposes has gained prominent and targeted effects.

Natural scene simulation is an important part of virtual reality technology. When flying on the sea, it is a unique experience with vast expanse, few referential landmarks, low visibility, and “pot bottom illusion”. In order to build a virtual system of marine combat flight environment with strong immersion, based on 4D stereo imaging system, the special texture fusion algorithm is used to simulate the cloud effect through the process of making, coloring, and fusion; the fluid system is used to simulate the sea surface; the method of surface triangle mesh custom polygon is used to simulate the illusion of very low altitude flight by means of deformation modification, etc. Finally, a realistic virtual reality system of marine combat flight environment is realized, which provides a reliable platform for marine flight psychological training.

This paper introduces the development of a oversea flight preadaptive training system-based 4D scene, which includes server, psychological data analysis and processing unit, oversea flight simulation scene play and control unit, seat control unit, special effect output unit, psychological stress test equipment, special effect seat and special effect equipment. The system can be used for the pilot to complete targeted psychological training in the four-dimensional space composed of three-dimensional video and environment, improve the psychological adaptability and tolerance to carry out combat tasks in the dangerous environment at sea and be familiar with the common operational modes of oversea flight, so as to eliminate the tension and fear.

Objective—to study the methods and procedures of autonomic nervous stability training for military pilots, then provide effective training program recommendations for all the training departments to organize and carry out autonomic nervous stability training for pilots. Methods—a total of 101 military pilots were studied, based on the three-step method, a three-stage autonomic nervous stability training was conducted for pilots by the physiological coherence and autonomic balance system (SPCS), the data of “0.1 Hz index” before and after each stage of training were collected and marked in chronological order as R1/2/3/4/5/6. Then analyze and evaluate the training effect. Results—there was a significant difference in the 0.1 Hz index before and after the pilot training, the post-training data R2/4/6, and the pre-training data R3/5 were significantly higher than R1; R3/5 is significantly lower than R2/4/6; there was no significant difference between R2, R4 and R6, or between R3 and R5. Conclusion—the three-stage pilot autonomic nervous stability training scheme, both in and without the system have remarkable effects. And the two trainings can be combined with each other.

Mental ability will decline by ageing while the experience accumulating. It is important to study the mental attributes of aged test pilots in order to maximum professional span and ensure flight safety. Methods A total of 35 experts including test pilots and aircraft design engineers were interviewed on the issues of the mental ability of aged test pilots through completing a questionnaire about the issue. A battery of mental ability test and 16PF were used to examine 37 test pilots who were divided into three age groups (age above 45 year, n = 16) and control group (age below 45 year, n = 21). Results Most important mental attributes of older test pilots were related to professional spirits, flying expertise (judgment) and personality. The firstly aging abilities were cognition and psychomotor ones. Scores of Detecting special graph, Distinguishing direction and Distracted listening were lower than those of control group (P < 0.05), which were negatively correlated to age (r = −0.335, −0.411, −0.409, P < 0.05). Conclusion Mental abilities related to reaction speed decline earlier. Although the expertise may compensate for the decline, routine aptitude test will benefit the increasing need for test pilot and aviation safety.

A comparative survey was conducted with 163 Chinese male pilots to build an anthropometric method based on computer graphics. 10 human body dimensions of point-to-point distance were gathered by extracted measurement based on computer graphic and traditional measurement in ISO7250 techniques. It was found that the extracted measurements were homogeneous with the traditional measurements in standardized Z scores, but there were systematic errors in raw data of the anthropometric method based on computer graphics. It suggested that the methodology based on computer graphics was well acceptable in views of ISO20685 because all mean differences were less than ±1.0 mm in 95% confidence interval after data correction by linear equation. Some factors were also discussed.
