Key Technology Research And System Implementation Of Electronic Flight Bag For General Aviation Based On IOS

With the rapid development of intelligent civil aviation,the general aviation industry has made remarkable progress.In recent years,the state has been committed to promoting the opening up of the general aviation sector and accelerating the reform progress of the general aviation industry.As a key component of civil aviation informatization,electronic flight bag has achieved initial success in the field of transport aviation,but has not been popularized in the field of general aviation.Most of the electronic flight bags used by domestic general aviation are developed and maintained by third-party companies,and lack of electronic flight bags with independent intellectual property rights.At present,the electronic flight bag used by domestic general aviation also has some problems.For example,the data transmission is not in time,the data security is difficult to guarantee,and the visualization effect is not good.Not only does it not reduce the flight burden of pilots,but also increases the risk of affecting flight safety.Therefore,this thesis uses Xcode of i OS platform as a development tool and combines the latest development technology of i OS to conduct detailed research on key technologies of electronic flight bag,and finally designs an electronic flight bag system suitable for general aviation.The main work completed is as follows:(1)Combined with previous design experience of electronic flight bag at home and abroad,this thesis firstly analyzes the requirements of the electronic flight bag system for general navigation,then designs it from the overall structure and business process,and finally divides the main functional modules of the system.(2)Design data processing and data transmission methods suitable for general aviation.A data exchange model with XML as the intermediate data format was proposed,and Alamofire was used to implement data transmission.(3)The design principle of visualization in general aviation EFB is analyzed,and the design idea of visualization in general aviation EFB is proposed.Finally,the visualization design method is obtained according to the design idea.(4)Detailed design of each module of the system based on Swift UI,specific functions of each module are realized,and integration of key technologies and core technologies is completed.The test results show that the thesis solves many problems that general aviation electronic flight bag system by researching and designing the key technology,optimizes the usage flow,and provides ideas for the development of general aviation electronic flight bag.
