Assessment of pre-launch functional state of pilots based on heart rate variability indicators

Background

Due to the active use of modern high-maneuverable aircraft in various regions of the world, there is still a need for medical support for pilots in order to ensure the efficiency and safety of flights. In this regard, it is important to study the reactions of pilots' bodies to the factors of their professional activities. One of the most significant issues is the dynamics of pilots' functional state during the pre-flight period and the severity of their pre-takeoff conditions.

Aim

To assess pilots' pre-flight functional state.

Methods

The study was conducted in field conditions with the participation of flight personnel who performed flights on modern high-maneuverable aircraft. Physiological and psychophysiological assessments were performed 24 hours before the start of the flight shift and on the day of the flights during the medical preflight examination. Seventeen pilots participated, divided into two age groups: 11 pilots aged 26 to 35 (group A) and 6 pilots aged 35 to 47 (group B).

Results

The change in the functional state of group A pilots during the pre-flight period is characterized by optimal tension of the regulatory systems and a moderate sympathetic shift in the autonomic balance, which corresponds to the pre-takeoff functional state and is considered normal. No similar changes were observed in group B.

Conclusion

Young pilots under the age of 35 have a pronounced state of pre-takeoff tension, which may be due to insufficient development of flight skills or psychophysiological preparation for flights. The severity of pre-takeoff tension in pilots may be influenced not only by age and total flight time, but also by the specifics of psychophysiological preparation for flights.
