SAFETERM

Current MALE RPAS Emergency Recovery (ER) and Flight Termination Systems (FTS) managing system failures in loss of C2 link mode are based on pre-programmed procedures depending on potential additional occurrences (i.e. combined failures conditions with loss of C2 link). This requires the definition of Flight Termination Areas (FTAs) during the mission planning activities taking into consideration the possible termination scenarios. Although in some cases this information can be updated during the flight, this limits the RPAS capability to react to unforeseen occurrences. Moreover, if an unforeseen situation occurs and a planned FTA is not reachable this will lead to an uncontrolled crash in the terrain. SAFETERM intends to solve this gap by computing alternative flight termination areas based on the flight range. The development of SAFETERM is being assessed based on the developments of SAE WG-114 and the Artificial Intelligence Guidelines provided by EASA. The main goal is to check the applicability of Learning Assurance, Explainability, and Safety Risk Mitigation strategies on a real use case. This is aligned with the main goal of the project, which in the end is to assess the certifiability of such AI-based systems in the aviation industry

RPAS EMERGENCY RECOVERY FOR SYSTEM FAILURES IN LOSS OF C2 LINK MODE

In Loss of C2 Datalink Mode the RPA will fly according to a pre-planned contingency route towards a suitable airfield. In case of an additional failure the RPA cannot reach the pre-programmed airfield, it will follow a pre-programmed emergency route to a Flight Termination Area.In this situation any degradation of the RPA status might turn unfeasible the termination in the FTA. In such a case the RPA will trigger SAFETERM, which will then compute an Alternative FTA within the flight range allowing a safer termination procedure.
