Two-Step Subjective Rating Technique of Pilot Evaluation in Q–Q Test for Aircraft Cockpit
- 418 Downloads
A two-step subjective rating technique was constructed to refine and validate the responses of pilots in Q–Q test for aircraft cockpit as a means of subjective data collection and problem diagnosis of designs on the bases of pilot judgment from points of user’s view in the context of simulated flight tasks. Twelve male pilots participated in the Q–Q test for pilot evaluation of a new cockpit prototype as 5th, 50th or 95th percentile representatives in stature. Each user made a judgment firstly about the tested design on the index with acceptability scale and then indicated the deficiencies in the design or the problems in use they found if they complained as “not acceptable” or “not satisfactory” in satisfaction scale, while pilot comments were verified. It is not allowed that only a level or rating score was made without a problem arising because the list of questions is very important as well as suggestions for improvement in Q–Q test. The final list of questions and suggestions was based on the consensus of users, but how to improve is the responsibility of the designer. The results and the influences were also discussed.
