In this paper, the design of controllable parafoil flight control algorithm is introduced. The multiphase flight control algorithm is devised with the principle of improving landing error accuracy and reducing control quantities, the critical parameters in this algorithm are ascertained by simulate optimize method. To validate and improve the parafoil flight control algorithm,the visualized simulation flight envirnment of the parafoil is established. The result of simulation in given conditions, including the trace of the parafoil system, the outcome of statistical analysis, and the process of reentry in three-dimension scene, can be shown in this simulation environment .
