Integration And Verification Of Guidance Function Of Flight Management System Which Based On IMA Architecture

Flight Management System is the key component of Aircraft Avionic core process system,which integrated the functions of guidance,flight plan,trajectory prediction,performance calculation,database,etc.to achieve the goal of auto flight,which largely decrease the load of pilot during the flight.Guidance function is very import function during the cruise.And in current stage,how to use combined navigation sensor to take place single sensor to ensure the save,comfort and fast flight has become the key research point of the navigation area.INS(Inertial Navigation System)and GPS(Global Position System)are two main navigation sensor of flight management system.This paper analysis the work theory of INS and GPS,build hybrid INS/GPS navigation system model based on Kalman filter algorithm.Integrated modular avionics(IMA)is widely used by civil aircraft project,it can provide a platform of sharing the configurable partitioning isolation resource,and health monitoring and fault management functions,and only allowed to reside in the application by the specified interface connected with other applications.Currently,there are two kinds of flight management system implementation,one is using an independent flight management computer hardware,the other is host application software resides in the Integrated modular avionics,this article focus on the view of the design and research of the host application software flight management system.Civil aircraft primary focus on Airworthiness certification.While,system integration and verification is an important part of the airworthiness of software.This paper research on the integration and verification method of flight management system,introduce flight management system development life cycle process.And bring out testing model for Flight Management system,According to the real project,describe the method requirement writing and the how to design requirements based test cases,test procedures.Besides,investigate on the importance of problem reports,change report,and set example for this two kinds of report,at last,introduces the composition and working principle of system integration verification platform and analyzed primary issue during the process of integration and verification.
