Biomechanical analysis of the dimensions of pilot seats in civil aircraft

The dimensions of pilot seats from five different types of civil aircraft w ere measured and the results compared with existing standards and biomechan ical criteria. It was apparent that these seats failed to meet requirements , particularly in the effective depth and inclination of the seat and in th e height of the lumbar support and the armrests. Hence, none of these seats made it possible for the pilot to establish a comfortable sitting posture. In comparison with aviation standards, the anthropometric dimensions were not satisfactory, meeting only 4-7 out of 10 requirements. The dimensions b ased on biomechanics were even less satisfactory, meeting only between 1 an d 3 requirements out of 7. (C) 1999 Elsevier Science Ltd. All rights reserv ed.
