In order to improve the fidelity and intuitiveness of the test and verification of the Ground Pro-ximity Warning System (GPWS), an overall technical solution of the test platform based on 3D scene and flight simulation for GPWS is proposed based on deep analysis of the principle and verification requirements of the GPWS.Considering the aircraft characteristics and real-time factors, a realistic flight simulation model is established, and the 3D alarm envelope is visualized by using the synthetic view.The GPWS function and performance test evaluation method is proposed, which can provide a comprehensive test for GPWS equipment and algorithms.
