Human-Computer Interaction Optimization Research On Cabin Pressurization And PBN Operation Of A320 Based On Calm Technology

With the diversification,complexity,and digitalization of civil aviation aircraft systems and operating environments,the development and popularization of new CNS/ATM technologies,and the extensive use of onboard computers,a large number of new concepts,information,and new technology equipment will follow.The amount and type of information has increased significantly.At present,the cockpit design of civil aviation airliners does not break away from explicitly conveying information to pilots and requiring pilots to evaluate and process.Flight crew will face and process massive and diverse data and new types of information with limited attention resources.This continuously puts forward wider and deeper requirements on the skills,rules,and knowledge-based capabilities of flight personnel,which brings excessive load and higher risks.This topic is based on the overall design of the cockpit of the Airbus A320 series(A320series include A318/A319/A320/A321,abbreviated as A320 s in the thesis),using the design concept of calm technology,through the integration of automatic information processing,integrating the relevant calculations with the environment,and realizing the optimization of human-computer interaction.The optimization scheme aims to simplify pilot information processing,reduce work load,and improve flight crew situational awareness,so that pilots can focus on flight tasks more naturally in terms of interaction with the aircraft and monitoring and processing of cockpit information without sharing precious attention resources itself.Aiming at the human-computer interaction problems of A320 series aircraft cabin pressurization and performance-based navigation exposed in actual operation,the theoretical analysis of A320 aircraft related technologies is carried out,using Microsoft Flight Simulator as the platform,programming and development based on the open source A320 module of the community are carried out to realize the optimization of human-computer interaction design.The control experiment between the native A320 and the optimized A320 of this topic was carried out through flight simulation experiment,and the appropriate indicators were selected and the NASA-TLX questionnaire was used to evaluate and compare the subject’s task performance and subjective workload to verify the optimization plan.Through the experimental results,it is found that the cockpit optimization scheme based on calm technology can improve the task efficiency of flight crew for specific flight tasks and subjects,assist in the timely identification,troubleshooting and correct decision-making of abnormal situations,and reduce the severity of incidents caused by abnormal situations,improve the situational awareness of the flight crew and reduce the workload,and reduce the possibility of wrong handling and decision-making.In this study,the optimization scheme of A320 cabin pressurization and performancebased navigation operations are verified by simulated flight experiments.Through the human-computer interaction optimization scheme of A320 cockpit pressurization and performance-based navigation operation and the flight simulation experiment verification,this study provides reference and prospect for the cockpit design research to adapt to the future operating environment.When coping with the massive amount of information in flight operations and adapting to new aviation technology applications,human factors and the overall view of the system must be considered in the design of human-computer interaction,rather than blindly adding new equipment,procedures and warnings and requiring more extensive active monitoring by the flight crew.
