21世纪对航空电子将面临降低成本，突破“信息障”适应新的作战环境、提高生存率、冲破人文阻力四大挑战。综合化技术、开放式系统结构、新型传感器、数据融合、模块化、先进的武器大控技术、大容量超高速计算技术、智能座舱、仿真等则是航空电子向纵深发展需要解决的关键技术 In the 21st century, the avionics will face the four major challenges of reducing costs, breaking through the “information barrier”, adapting to the new combat environment, improving survival rate and breaking the human resistance. Integrated technology, open system architecture, new sensors, data fusion, modularization, advanced weapons control technology, large-capacity ultra-high speed computing technology, intelligent cockpit and simulation are the key technologies that need to be solved for the further development of avionics
