英文摘要：

Automatic flight system plays an important role in reducing pilots workload and improving flight safety. The relative airworthiness specification was analyzed. The basic principle and software development tools were studied for flight mode design. Furthermore, the airworthiness compliance validation methods for flight mode were explored. A platform for flight modes design and simulation was developed, in which the flight modes and transition scheme could be designed by MATLAB/Stateflow, pilots control inputs were received by MATLAB/GUI, a flight dynamics model was used for real- time flight simulation. Consequent- ly, a closed- loop platform combined with flight mode design, simulation and validation was built up. It can be further applied for flight mode design and airworthiness analysis.
