In order to solve the inadaptability of Augmented Reality (AR) application system in universality and integration

and meet the practical requirements of aircraft assembly

this paper presents a new Aircraft Assembly AR Intelligent Pilot System (A3-IPSAR). Firstly

two key technologies

universal AR assembly instructions based on dynamic operation description and integrated operation pilot based on continuous operation state

are studied. Secondly

an AR intelligent pilot system is constructed for aircraft assembly operation. Finally

the system is applied to pipeline assembly of aircraft hydraulic system in laboratory environment. It is preliminarily realized that the real-time pilot and intelligent inspection applied in the assembly process of hydraulic pipelines are feasible.
