The development and troubleshooting of helicopter avionic systems is becoming more and more complex because of the huge amount of data exchanged between the various equipments that make up these systems. This makes it very complex to specify, validate and test avionic systems, either on the ground (bench) or in flight. To help design systems, EUROCOPTER is currently developing a new tool called SDMU (System Digital Mock-Up) to be used in the future concurrently to the system specification process, in order to reduce both development time and technical risks. The SDMU would consist of a real-time simulation that will enable representing the interfaces between the equipments. The level of fidelity of these simulations allows to evaluate, to modify and to pre-validate the avionic interfaces in a full virtual environment without any physical equipment in the loop. After presenting the principles of SDMU, this paper highlights the projected benefits of SDMU and describes how the simulation is built within the system specification process. The projected benefits of this new tool are illustrated by an example of the forecast use of SDMU in the system specification process and the in-depth investigation methods is illustrated by a forecast example related to temperature management within the hydraulic system.
