| Objective To study the HALT scheme and the implementation of a civil aviation airborne electronic equipment and improve the reliability of the equipment. Methods Targeted HALT scheme was designed based on the statistical distribution of environmental stress and failure and in combination with the characteristics of a civil aviation airborne electronic equipment, and HALT test was carried out. Results After discovering several design defects and making rectifications thereof, the reliability of the airborne electronic equipment of the civil aviation was greatly improved. Conclusion Through the design of targeted HALT scheme and the implementation thereof, we have found the design defects and made improvements accordingly, with which the reliability of the equipment can be effectively improved. |
