The Implementation of Aeronautical Information Exchange Model in SWIM

System Wide Information Management (SWIM), as an advanced civil aeronautical information management method, aims to solve the problems of global civil aeronautical information systems such as difficulty in obtaining common data in a timely manner and high information exchange costs. SWIM was first proposed by Europe and the United States and was recognized and valued by the International Civil Aviation Organization. It is to ensure the correct information transmission at the correct time. In order for the consistent information in the “virtual information pool” to be efficiently, accurately and securely transmitted, the information and data in the SWIM environment need to be defined in detail and standardized, so the two sides of data interaction can maintain the consistency in syntax and semantics. The Aeronautical Information Exchange Model (AIXM) is a core standard model for data transmission and format conversion, which mainly involves information in the aeronautical intelligence field. It covers multiple thematic elements such as airspace, airports and air routes, and provides a standardized description for data conversion and transmission in this field. The article analyzes the model composition of AIXM in the SWIM information exchange model, the modeling process, and the key technologies involved in model establishment, and preliminary design and implementation of AIXM.
