Study of NASA-TLX and Eye Blink Rates Both in Flight Simulator and Flight Test

摘要

In order to determine the minimum flight crew number and to show compliance with aircraft airworthiness regulations of CS25.1523, the workload of flight crew should be measured in various fight scenarios both in flight simulator and in flight test. However, the complexity, environment and safety consideration of flight test requires flight crew to take more responsibility and more careful with decisions and actions with higher stress, and it may be inappropriate to carry out the flight test in a high-risk abnormal situation. Therefore, it is necessary to assess workload measures in a simulator to predict in-flight behavior. In this research, NASA-TLX and eye blinks rate were compared, both in flight simulator and in flight test in three flight scenarios, including Standard Instrument Departure. Manual Departure, and Standard Instrument Approach. This study were carried out in a CRJ-200 full - flight simulator and an aircraft, and a total of nine pilots were participated in. According to the results, both flight scenarios and environments had the significant influence on NASA-TLX. However, eye blinks rate only manifested significant differences in flight environment. Furthermore, the relation between NASA-TLX and eye blinks rate are weak between simulator and flight test. Therefore, in order to reduce the quantity and risk of compliance demonstrating flight test, it is necessary to figure out more significant psychophysiological measurements.
