Abstract: Technologies including miniaturization of computer, Internet of Things (IoT), wireless broadband commu-nication and Artificial Intelligence (AI) are developed rapidly in recent years and bring significant impact to society. As enabling technologies in aviation application, these technologies will cause revolutionary changes to domains including aircraft design, aircraft flying, maintenance support, etc. Future aircraft will have powerful ability to intelligently perceive and process surrounding information, be multi-dimensionally connected with IoT through integrated space-ground information network, and accomplish intelligent flight, maintenance, operation business processes and so on by combining with the intelligent ground supporting system. For these new technologies mentioned above, this article summarizes their current development situation and application prospect on air passenger transportation industry. Based on these enabling technologies, this article proposes a concept of intelligent air passenger transportation system taking full advantage of the integrated space-ground information network, designs the sys-tem architecture, describes the typical application scenarios, and identifies several key techniques and challenges. The research results are helpful for manufacturer to better design intelligent airplane for future, and for airline to efficiently operate and manage intelligent airplane.

Key words: air passenger transportation system, integrated space-ground information network, intelligent flight, intelligent maintenance, intelligent operation, intelligent cabin service
