“…Familiarization and individualization for cognitive fatigue, attention, and working memory tasks were conducted on the second visit. The participants conducted PVT and the 1-Back tests 3 times each in a familiarization session (Ercan & Gunduz, 2020). The TloadDback individualization was conducted after finishing the PVT and the 1-Back familiarization after a 20-minute break.…”

“…Pilots operate in highly stressful situations that require multitasking and high cognitive demand. The workload of pilots increases during aircraft control, cognitive distraction, and gravity force (Ercan & Gunduz, 2020;Mohanavelu et al, 2020;Hebbar et al, 2021). Prolonged periods of intense and sustained activities in pilots can cause cognitive fatigue that leads to impairments in psychomotor performance, increases safety risk, and reduces aviation safety.…”

“…Psychomotor vigilance and/or sustained attention are the crucial cognitive domains to prevent fatigue-related errors and risks in aviation (Boudreau et al, 2018;Maki et al, 2022). Cognitive fatigue superimposed on the gravity force and hypoxic exposures reduces brain perfusion and cerebral oxygenation, both of which are associated with attenuated cognitive function (Konishi et al, 2019;Ercan & Gunduz, 2020).…”

Background: Military pilots operate in stressful situations that require multitasking and high cognitive demand. Prolonged periods of intense and sustained activities cause cognitive fatigue that leads to impairments in cognitive and physical performance. Frequent action video gaming is associated with enhanced attention and accuracy and could attenuate cognitive fatigue in military pilots in training.Aim: This study investigated the effect of time load dual-back task (TloadDback), an effective method in inducing cognitive fatigue, on cognitive function in habitual video gamers and non-gamers among military pilots in training.Methods: Thirty male student pilots (25 ± 1 years) were divided into those who had habitually played action video gaming (n = 15, gamers) and those who had not (n = 15, non-gamers). All participants performed a psychomotor vigilance task (PVT) and 1-Back tasks before and immediately after cognitive fatigue induced by the TloadDback. Results and Conclusion:After the cognitive fatigue task, subjective fatigue ratings increased significantly in both groups. The reciprocal reaction time and middle cerebral artery blood velocity (MCBV) decreased in both groups. The non-gamers' reaction time during 1-Back significantly reduced (p < 0.05) but increased in gamers. The changes in MCBV were negatively associated with corresponding changes in hemoglobin index (r = -0.599, p = 0.001). In conclusion, cognitive fatigue result in reductions in attention, and cerebral blood velocity in military pilots in training. Habitual gamers demonstrated reduced tolerance to cognitive fatigue than non-gamers presumably through reduced cerebral oxygenation.

The design process of a new aircraft (AC) is always associated with the issue of choosing its basic technical parameters, or, in other words, the formation of its conceptual design. In case of a civil aircraft, the choice of these parameters is defined by the requirements for operational safety, market conditions, norms that specify the tolerable harmful impact of the aircraft on the environment, etc. In case of a military aircraft, its outlay mostly depends on the concept of potential military threats, ways of using the military aircraft in military conflicts. Some of these requirements are formulated in regulatory documents – the Aviation Requirements for Civil Aircraft and the General Tactical and Technical Requirements of the Air Force for Military Aircraft. For example, Part 25 of the Aviation Requirements for Civil Aircraft defines the Airworthiness Standards for transport aircraft. It should be noted that the stated above requirements are often a tool of competition, for example, when tightening the aircraft noise abatement procedures provides advantages for particular manufacturers, not admitting other manufacturers to enter the market, whose aircraft do not conform to the new standards. Thus, complying with the requirements virtually involves additional costs both in the aircraft development and during its operation. In addition, the implementation of the requirements stated above can lead to the deterioration of the aircraft’s performance, and hence, to the decrease of its competiveness and combat effectiveness. Therefore, each requirement of the regulatory documents should have a profound scientific rationale. This article analyzes one of the regulatory documents requirements referring to the necessity of anti-g system on board aircraft. The authors propose the approach to specify the existing criterion to provide the scientific basis for the anti-g system on board aircraft by assessing the actual level of pilot load when maneuvering. The subject under study is of particular importance for the Yak-152 trainer aircraft. The actual level of loads during pilotage of the Yak-152 trainer aircraft does not require the use of the anti-g system but if to be based on a formal criterion, namely, in terms of the maximum operational overload value, the aircraft should be fitted out with such a system.
