The study aims at developing possible architectures to implement the functionalities of a future Mission and Trajectory Management System (MTM) the requirements of which have been defined during the CleanSky GRA-4.1.1 Aircraft High Level Requirements study. The GRA3M study will analyse these requirements:

• Perform a market survey to find hardware and software COTS components to implement these requirements
• Define architectural solutions using these components and meeting the MTM requirements
• Perform a SWOT analysis comparing the proposed architectures using parameters like weight, volume, power consumption, safety, security, maintainability, robustness etc.

The architectures to be studied follow different paradigms within and beyond of the state-of-the-art in avionics architecture. These paradigms are: Federated Architecture Current Integrated Modular Avionics (IMA) like it has been applied, for example, in the A380 and A350 programmes. Next generation IMA technologies (IMA2G) that are currently under investigation by European projects like DIANA (FP6) and SCARLETT (FP7). Skysoft is convinced that a thorough analysis of these three approaches will bring out the best possible architecture meeting the MTM requirements and strengthening the objectives of CleanSky and related programmes like SESAR.

With the introduction of concepts beyond of the state of the art, further weight and volume reduction of on-board systems, enhanced reusability as well as more efficient development processes can be achieved than it would be possible with today’s technologies only. Developed by a unique team with extended expertise in the aeronautical domain, at the end of this study a detailed report presenting the most applicable avionics architectural solution, and related SWOT analysis, will be made available.
