The ASTRAEA project is a £32M UK initiative to develop the safety case for unmanned aerial vehicles flying in commercial airspace. It is addressing both the issue of what needs to be covered by such a safety case, and how such a safety case can be constructed efficiently. One of the key areas within the remit of ASTRAEA is that of generating diagnostics capable of correctly identifying the causes of all possible failures of the vehicle. This paper describes how model-based simulation can be employed to automatically generate the system-level effects of all possible failures on systems within the aircraft. The results of the simulation can be used in several ways. They can be used to produce a system-level FMEA for aircraft systems. They can be used to identify the sensors necessary to discriminate remotely between different failures on the aircraft. Once a set of sensors have been chosen for placement on the vehicle, the simulation results can also be used to generate diagnostic and prognostic software for deployment on the vehicle. Using the automated safety analysis software developed on the ASTRAEA project is more efficient than doing the same work without the software, and also provides a guaranteed level of performance.
