Research On The Influence Of Character Color Coding On The Compatibility Of Head Up Display And Head Down Display

Head up display and Head down display are important displays that provide pilots with flight reference information.The compatibility of the two will directly affect the operational performance of the crew and the flight safety of the aircraft.When the display information is relatively dense,it can help for the crew to capture important information needed,and effectively improve the speed of search information by enhancing the salience of information.Using the color coding to enhance the prominence of information is an effective measurement.Therefore,based on the simulation platform,this paper studies the influence of character color coding on the compatibility of HUD and HDD for the approach flight phase.The research content mainly includes the following points:(1)The airworthiness items of the cockpit human factors and the standard of HUD design are interpreted.The proposed requirements for the HUD color coding design and the compatibility between HUD and HDD during the display conversion are clarified.(2)Based on airworthiness items and related flight training manuals,and combined with the model experimental platform,experiments on the compatibility of character color coding for HUD and HDD were carried out.In order to avoid the problem that the sensitivity of the unilateral assessment is not obvious,this paper adopts indicators from three aspects such as physiology,performance and subjective,therefore,we can assess under what color coding conditions,the psychological mental workload and performance of the subject is the best.(3)A single factor analysis of variance was used to analyze all the indexes,and a significant index of the main effect was obtained.The sensitive indexes are summarized and analyzed to explore under what color coding conditions,the compatibility of HUD and HDD is better.(4)From three aspects of eye movement,performance and electrocardiogram,the multiple linear regression model of situation awareness was built.This model will have a certain reference value for predicting scene consciousness,guiding the design of human-computer display interface and reducing flight error.
