“…The results confirmed that young pilots are more susceptible to SD than older pilots, indicating that this questionnaire played a due role in evaluating SD. Similar results were reported by Wang et al [25] and Sharon Holmes et al [26]. They found a significant difference in the score of the scale with or without SD flight experience.…”

BACKGROUND: Spatial disorientation (SD) is a problem that pilots often encounter during a flight. One reason for this problem is that among the three types of SD, there is no validated method to detect the Type I (unrecognized) SD. OBJECTIVE: In this pursuit, initially we reviewed the problems and the evaluation methods of associated with SD. Subsequently, we discussed the advantages and disadvantages of the subjective questionnaire evaluation method and the behavior evaluation method. METHODS: On the basis of these analyses, we proposed a method to detect the unrecognized SD that improved the assessment of SD to a significant extent. We developed a new direction to study the unrecognized SD based on the subjective report and the center of pressure (CoP). RESULTS: The proposed evaluation method can assist the pilots to understand the feelings and physical changes, when exposed to unrecognized SD. CONCLUSION: We hope that this evaluation method can provide a strong support in developing a countermeasure against the unrecognized SD and fundamentally solve the severe flight accidents arising due to them.

“…When the illumination is larger than 2000 lx or less than 1000 lx, the ergonomic evaluation value decreases significantly, which is not conducive to flight safety. By comparing the results of work performance evaluation, physiological workload evaluation and mental workload evaluation, it can be concluded that their exists high performance with high load in the illuminance ranging from 100 lx to 2000 lx and 2000 lx to 3000 lx (Figures 6,7,8,9). This result shows that the workload and work performance are not strictly negative correlated, appropriate workload can promote performance.…”

“…In 2018, Feng Chuanyan et al proposed a situational awareness cognitive prediction model based on the multiresource load theory to quantify attention resource allocation [7], however it did not involve the quantitative representation between workload and attention resource allocation. In 2019, Jenhung Wanga et al proposed a method based on the combination of psychological test and Rasch model to evaluate pilots' ability on coping with spatial disorientation caused by mechanical design with psychological workload [8], so as to find the aviation cockpit design with the lowest workload and optimal ergonomics. In 2019, Manttari et al studied the relationship between activity level and workload [9], and gave a quantitative evaluation of the effect of human activity based on workload.…”

To instruct interior lighting design of aviation cockpit and ensure the work efficiency and comfort of pilots, and reduce safety accidents caused by light environment and visual fatigue during flight, it is important to establish a multi-dimensional ergonomic evaluation mechanism of cockpit light environment. In this paper, by improving Jdms' mental load theory, we establish a thorough experimental scheme based on physiological workload, mental workload, work performance and physiological work performance to evaluate the cockpit ergonomic under different light environment multi-dimensionally. Firstly, 12 evaluation indexes including job accuracy, job speed, blinking, heart rate variability, average fixation time, saccadic speed, mental demand, physical demand, operational performance, time demand, degree of confusion and degree of effort are obtained through the experiment, and then the weight of each evaluation index is calculated by entropy method to construct the ergonomic evaluation model. The evaluation results of physiological workload, mental load, work performance and physiological work performance were combined to obtain the final ergonomic evaluation results. According to our experimental results, it was found that light environment for pilot to get the highest ergonomic efficiency is 1500 lx light illumination and 5000K color temperature. The results provide a reference for the ergonomic experiment of aircraft cockpit and the design of aviation cockpit lighting system.

“…Respondents can choose from four options: uncertain, non-conforming, relatively conforming, and fully conforming according to their actual situation. In the statistical analysis of the questionnaire results, uncertain and non-conforming are regarded as negative attitudes, and relatively conforming and fully conforming are regarded as positive attitudes ( Wang et al, 2019 ).…”

To enable all college students to have positive psychological quality and sound personalities, their potential should be fully realized, and their comprehensive ability should be improved to adapt to society. Empirical research is carried out by means of questionnaires, and the relationship between psychological quality education and the mental health level of college students is studied through correlation analysis and regression analysis. Firstly, the problems existing in college students’ psychological quality education are summarized from the perspective of educational psychology through questionnaires. Secondly, the data of college students’ psychological quality education and mental health level are collected, and the general situation and the relationship between college students’ psychological quality education and mental health level are analyzed and discussed by processing the existing data. The research results show that 51% of college students think that psychological quality education is only needed when there is a psychological problem; 47% of college students believe that the current educational content of the school’s psychological quality education focuses on the prevention and solution of students’ psychological problems; 83% of the students consider that the psychological quality education currently carried out by the college still adopts the more traditional teaching methods such as classroom lectures, psychological counseling and special lectures. In the process of predicting college students’ mental health level, psychological resilience plays a significant role, which can predict 21.1% of variables. Psychological resilience and optimism can jointly predict 26.4% of variables. These contents broaden the research field of college students’ psychological quality education, enrich the related research on it, and provide a reference for the intervention of college students’ psychological health in school situations.
