title: [Effect of inclination angles of supporting surfaces og aircraft seat on pilot's working capacity in long-duration flight].
abstract: Results of experimental evaluation of the performance of pilots bound to stay up to 24 hrs in the working pose as a function of inclination of supporting surfaces (backrest and seat) are presented. Small inclination angles (up to 23 degrees) were found to be more provocative of discomfort, painful sensations and work deterioration characterized by higher intensity. It was shown that periodic change of the seatback inclination is an effective way to prevent fatigue in pilots on long-duration flights and to prolong time of comfortable stay in forced posture up to 12-16 hrs. The data on the time of comfortable stay and dynamics of pilot's performance as a function of angles of supporting surfaces of the seat laid the grounds to determination of the best combination to provide comfort to pilot on flight.
