Experimental Study on Display Format of Target Range for HUD of Aircraft

摘要

An experiment was conducted to explore the optimal display format of target range for HUD of aircraft. An integrated display format with trigon attached to the target designator was defined and compared with a separable display format of fixed scale with level linear indicator. The cognitive tasks were of extractive task versus integrative task in simulated flight with 2×2 within-subject experiment design. There were 151 Chinese male pilots participating in the human factor test. Results were found that the integrated display format of target range was recognized much better and faster in performance of 7.61% increments in correct reaction and 1.16s decrements in correct reaction time compared with the separable format and approved by 90.76% of the pilots. The conclusion was made that the integrated display format of target range could improve cognitive performance of target range information in HUD of aircraft on the basis of discussion.
