VISION stands for "Validation of Integrated Safety-enhanced Intelligent flight cONtrol" and is a European H2020 Mobility Growth aeronautics and cooperation project between Europe and Japan awarded to validate smarter technologies for aircraft Guidance, Navigation and Control (GN&C) by combining:  vision-based systems and  advanced detection and resilient methods.
TASC is leading WP4 "Dissemination" and is involved in WP3 contributing to the development and flight testing of fault detection, diagnosis (FDD) and fault tolerant control (FTC).

Despite continuous improvements in reliability and performance, the complexity of Flight Control Systems (FCS) also requires to use many sources likely to suffer from faults and environmental conditions. To overcome these anomalies, recent European and Japanese projects have evaluated advanced solutions, but their transfer to the industry is slowed down by lack of flight validations, limitations of on-board computers or certification issues.
The Technological Readiness Level (TRL) reached by both sides are rather equivalent, with dissimilar pros and cons: while European methods comply with industrial and regulatory constraints, Japanese ones have focused on flight-testing on their aircraft experimental platforms. Accordingly, VISION aims at capitalizing on the know-how and experience independently acquired by Japan/Europe to make a significant improvement and maturation of the TRL achieved for the studied FCS techniques.
To enhance air transport safety, the main objective of VISION is to validate smarter technologies
for aircraft Guidance, Navigation and Control (GN&C) by including:
1/ vision-based systems
2/ advanced detection and resilient methods.
With respect to the first point, and as the name suggests, one of the key features of this VISION project is the utilization of on-board vision system. From the perspective of detecting and handling flight anomalies, usually the flight control performance failure is detected by Fault Detection and Diagnosis (FDD) techniques using proprioceptive sensor measurements. However, if it is caused by an aircraft physical system failure such as an actuator jamming, it can also be detected by visually monitoring the aircraft. Based on this idea, the VISION project proposes a vision-based control surface monitoring system which provides additional information or confirmation and will be fused with the more classical FDD techniques. In addition, VISION will investigate vision-aided local precision navigation systems which covers poor GNSS integrity. In the case of accuracy degradation in the GNSS signals, the vision-based measurements can be fused with the degraded GNSS information to maintain precision in the navigation performance. At the same time, visual sensing technologies and image processing algorithms will be investigated which can provide the required vision information accurately and robustly even in degraded visibility conditions.
With respect to the FDD/FTC techniques studied (the second point above), VISION will build on the results from the precursor FP7 projects (ADDSAFE and RECONFIGURE) and the equivalent Japanese projects (AFCG and IFTC). These techniques include H-infinity, LPV, sliding mode, online parameter tracking and adaptive control. But in opposition to the previous projects, VISION focuses on their consolidation for real-time implementation feasibility and on the effective matching of the FDD and FTC algorithms.
