Airborne flight management system (FMS) with the ability in aspects of navigation, flight planning and guidance is one of the core subsystems in the modern avionics system, assisting the pilots in managing the entire flight and relieving the crews from the heavy workload as well. The essential role of the FMS requires the high quality performance in all-phase development especially in the function design. However, the textual design documents are utilized as media in the traditional document based methodology to be transferred to the downstream hardware/software development. One of the problems is the lack of ability to track the requirement efficiently in all lifecycle development. Another one is the ambiguity problem introduced by the textual description. In addition, the design output in terms of multi related documents may increase the inconsistence possibility when any modification is required. Therefore, it attempts to introduce the method of Model Based System Engineering (MBSE) using the system modeling language in the FMS design process to increase the trace ability and furthermore the product quality. The author then tries to use the integrated navigation function of FMS as an example to implement the new method in the design process, as the entire flight management system is a high complicated and multidiscipline covered system.
