The Effect of Expertise during Simulated Flight Emergencies on the Autonomic Response and Operative Performance in Military Pilots

Abstract

Heart rate variability (HRV) and performance response during emergency flight maneuvers were analyzed. Two expert pilots (ages 35 and 33) and two rookie pilots (ages 25) from the Portuguese Air Force participated in this case–control report study. Participants had to complete the following emergency protocols in a flight simulator: (1) take-off engine failure, (2) flight engine failure close to the base, (3) flight engine failure far away from the base, and (4) alternator failure. The HRV was collected during all these maneuvers, as well as the performance data (the time it took to go through the emergency protocol and the subjective information from the flight simulator operator). Results regarding autonomic modulation showed a higher sympathetic response during the emergency maneuvers when compared to baseline. In some cases, there was also a higher sympathetic response during the emergency maneuvers when compared with the take-off protocol. Regarding performance data, the expert pilots accomplished the missions in less time than the rookie pilots. Autonomic modulation measured from HRV through portable devices can easily relay important information. This information is relevant since characterizing these maneuvers can provide helpful information to design training strategies to improve those psychophysiological responses.

Comparing Response Behaviors to System-Limit and System-Malfunction Failures with Four Levels of Operational Proficiency

“…When unexpected events occur during flight, experienced pilots require shorter response times to make appropriate operations compared to novices. This has been confirmed by numerous studies [29][30][31]. However, these previous research articles usually focused on predictable situations (similar as system-limit failures), neglecting the consideration of unpredictable circumstances and the performance differences caused by different types of failures at various proficiency levels.…”

“…Hand strength, leg strength, and respiratory muscle strength were analysed before and after the event. All analyses were conducted following previous procedures and analysis systems [ 18 ].…”

The effect of Ashtanga-Vinyasa Yoga method on air force pilots’ operational performance

“…Changes in Operative performance—Flight times to complete tasks in the flight simulator; number of errors during the emergency protocol and their classification report from the flight simulator controller ( 12 ). The assessment will determine if the exercise protocol influences the pilot’s decision-making, as evidenced by improved task efficiency, reduced errors, and enhanced visual and auditory reaction times ( 1 , 2 )—Time Frame: measured at 12 weeks (vs. baseline values).…”
