航空电子系统数据网络在过去的二十年里，迅速发展的航空电子系统技术已在系统能力和性能方面发生了很大的飞跃，而开发、生产和支持航空电子系统的成本也大大增加了。目前，人们已认识到未来的技术不仅要加强任务的有效性，而且更加强灵活性和低生命周期成本。人们应广泛地考 Avionics Systems Data Network In the past two decades, the rapidly evolving avionics technology has taken a big leap forward in system capabilities and performance, and the costs of developing, manufacturing, and supporting avionics systems have increased dramatically. At present, people have realized that the technology of the future should not only enhance the effectiveness of the mission, but also be more agile and have lower life-cycle costs. People should test extensively
