Pilots also experience spatial disorientation (SD) when flying. One factor contributing to this issue is the lack of a validated procedure for detecting Type I (unrecognized) SD. Most of the current literature focuses on recognized SD evaluation methods, but there are few reports that concentrate on unrecognized SD evaluation methods. We go through some of the issues with SD and compare the various SD assessment approaches. We report on the benefits and drawbacks of the quantitative questionnaire assessment process and the behavior evaluation method in these books. We suggest a tool to diagnose unrecognized SD based on these analyses, which improves SD estimation in many ways. Centered on the subjective report and the core of strain, we establish a new approach to studying unrecognized SD (CoP). This latest approach compensates for the lack of unrecognized SD identification. We will help the pilots appreciate their emotions and physical adjustments as they are subjected to unrecognized SD by using the latest appraisal process. This assessment approach is hoped to provide good encouragement for unrecognized SD countermeasures and profoundly overcome the serious flight injuries induced by unrecognized SD.
