欧洲单一天空空中交通管理研究（SESAR）项目是欧盟委员会欧洲单一天空倡议的技术支柱，旨在实现空中交通管理（ATM）的现代化。在本文中，我们介绍了SESAR的建立过程和该项目的主要部分：研发部分（由SESAR联合执行）、部署部分（由SESAR部署管理方管理），以及欧洲空中交通管理总体规划（汇集并说明了各种研发和部署需求）。在新冠肺炎疫情暴发前不久，实施了最新的欧洲空中交通管理总体规划。疫情给空中交通造成了巨大损失，航空业的恢复也需要时间，为此需要重新确定工作的优先级，最主要的工作内容仍然是与环境相关。

The Single European Sky ATM Research (SESAR) project is the technological pillar of the European Commission's Single European Sky Initiative to modernize air traffic management (ATM). Here, we describe the process of establishing SESAR and the main parts of the project: the research and development (R&D) part, which is led by the SESAR Joint Undertaking; the deployment part, which is managed by the SESAR Deployment Manager; and the European ATM Master Plan, which collects and lays out both the R&D and deployment needs. The latest European ATM Master Plan was adopted just prior to the current pandemic. The huge loss in air traffic due to the pandemic, and the speed of the recovery of the aviation industry will require reprioritization, but the main elements that have been established—particularly those in support of the environment—remain valid.
