AI Article Synopsis
- Flight accidents triggered by spatial disorientation (SD) pose significant risks to aviation safety, yet research on this issue is limited.
- An experiment involving 10 pilots and 10 non-pilots aimed to evaluate SD by inducing it through video stimuli, gathering subjective feedback and center of foot pressure (CoP) data.
- Results showed pilots experienced fewer self-reported SD events compared to non-pilots, and their CoP variability was significantly lower, highlighting their better ability to recognize and manage SD, which could help decrease flight-related accidents.
Article Abstract
Background: Flight accidents caused by spatial disorientation (SD) greatly affect flight safety.
Objective: Few studies have been devoted to the evaluation of SD.
Methods: 10 pilots and 10 non-pilots were recruited for the experimental induction of SD. Videos for giving optical flow stimuli were played at two different flow speeds to induce SD. Subjective judgment and center of foot pressure (CoP) data were collected from the tests. The data were combined to determine the occurrence of SD and analyze the SD types.
Results: The number of self-reported SD events was slightly smaller in the pilots than in the non-pilots. The average upper bound of the confidence interval for the standard deviation of CoP was 0.32 ± 0.09 cm and 0.38 ± 0.12 cm in the pilots and non-pilots, respectively. This indicator was significantly lower in the pilots than in the non-pilots (P= 0.03). The success rate of the experimental induction of unrecognized SD was 26.7% and 45.0% in the pilots and non-pilots, respectively.
Conclusion: The method offered a new to analyze unrecognized SD. We could determine the occurrence unrecognized SD. This is an essential means of reducing flight accidents caused by unrecognized SD.

Multi-Attribute Task Battery (MATB) is a computerized flight simulator for aviation-related tasks, suitable for non-pilots and available in many versions, including open source. MATB requires the individual or simultaneous execution of 4 sub-tasks: system monitoring (SYSMON), tracking (TRACK), communications (COMM), and resource management (RESMAN). Fully customizable, the design of test duration, number of sub-tasks used, event rates, response times and overlap, create different levels of mental load.

Introduction: Fighter pilots must support the effects of many stressors, including physical and psychological exertion, circadian disturbance, jet lag, and environmental stress. Despite the rigorous selection of military pilots, those factors predispose to failures in physiological compensatory mechanisms and metabolic flexibility.
Objectives: We compared through NMR-based metabolomics the metabolic profile of Brazilian F5 fighter pilots with different flight experiences vs.

Cardiovascular autonomic regulation in fighter pilots: Lessons from active standing tests.

Article Synopsis
- Fighter pilots experience unique cardiovascular challenges during flights that affect their heart's autonomic regulation, leading to less effective recovery after stress compared to non-pilots.
- A study compared 9 fighter pilots to 12 non-pilots, measuring heart rate variability during different phases including supine rest and active standing, which mimics in-flight demands.
- Results indicated that fighter pilots had reduced sympathetic and vagal responses during recovery, suggesting that their bodies may struggle more than non-pilots to return to baseline after stress.
