Abstract:
Objective To evaluate mental workload of the pilots in different phases of simulated carrier flight for enhancing flight performance and ensuring flight safety.Methods Ten male pilots participated in the study.The subjective mental workload of pilots was rated by modified multidimensional National Aeronautics and Space Administration task load index (NASA-TLX) questionnaire after the traffic pattern flights in simulator.Results The overall mental workload rating scores in the take-off,downwind leg cruising,base turn and the final approach landing phases were 54.22±16.74,40.68±17.76,61.08±17.80,86.64±6.37 respectively.The pilot's mental workload in landing phase was significant higher than that in other three phases (F=15.613,P＜ 0.01).So did the score of mental demand tested by six dimensions of the NASA-TLX questionnaire (F=34.944,P＜0.01).The scores of temporal demand and effort during the landing phase were significant higher than those during the take-off phase and downwind leg cruising phase (F=5.653,3.344,P＜0.01 or 0.05).The scores of physical demand,performance and frustration had no significant differences among 4 flight phases.Conclusions Analysis of the TLX scores reveals that the carrier pilots have the highest subjective mental workload in landing phase as compared with that in other phases,and such significance may relate to the extent of mental demand,temporal demand and effort.
