The research of glider pilot’s flying quality influencing personal stressors Aim of the study:To estimate the personal stressors influence to the flying quality of glider pilot’s. Methods:The instantaneous analytic research using questionnaires was made during the European gliding championship. Two types of questionnaires were created in English and given for the participants (n = 90) to fill every day, 90 before the flight and 90 after. All together 1.260 questionnaires were given and 742 were returned (58.9%). Statistical analysis was made with „Statistica for Windows“ and Microsoft Excel programs. Results:Subjective pilots fatigue average increased 18.57% during the flight (stdev. 25.02%). At first fatigue increased, later decreased and at the end of the championship increased. Fatigue were increased by personal stressors, like the rest (r = 0.19, p<0.05), sleep duration (r = 0.15, p<0.05), coffee usage (r = 0.17, p<0.05). Fatigue decreased with tea usage (r = -0.19, p<0.05), short time of awake (r = -0.18, p<0.05). Most glider pilot’s noted that various health changes didn’t influence flying, but sweating importuned little. That was approved by objective measurements. Final results were determined by every day points (r = 0.57, p<0.05), pilot’s experience (r = 0.29, p<0.05), total flight time (r = 0.25, p<0.05), flight’s distance (r = 0.25, p<0.05), tea usage (r = 0.16, p<0.05), rest (r = 0.14, p<0.05). Negative influence to the results were made by sweating (r = -0.21... [to full text]
