Research on software testing technique of airborne equipment based on airworthiness

According to the characteristics of the airborne embedded software, the airworthiness-based software testing technique and testing standard are systematically researched. The verification process of DO-178B standard is analyzed. The software integration testing process of airborne TCAS (Traffic Alert and Collision Avoidance System) is designed. The TCAS software testing project is finished in the hardware testing environment with the software testing tools. The improvement of the testing procedure defects are analyzed. Test result and the comparsion results are presented and analyzed. The correctness and the versatility of the testing model and the testing process are approved by the test examples.
