Final Workshop

H2020 VISION EU - Japan joint final workshop

Smarter Flight Control Technologies for enhanced safety

26 - 27 August 2019

ONERA Toulouse Research Center







Due to the continuous improvements in reliability and performance, the increased complexity of Flight Control Systems (FCS) of commercial aircraft necessitates the use of many data sources which can suffer from degradation due to faults and external environmental condition changes. Development of “Smarter” flight control technologies is a key to enhance air transport safety by embedding fault-resilience in the FCS design to extend its functionalities and by providing more assistance to the pilot.

Recent European and Japanese projects have developed new advanced Guidance, Navigation & Control (GN&C) solutions that can automatically detect and overcome certain critical flight situations to ease the pilot workload, but their transfer to industry has been hindered by a lack of flight validation, the limitations of on-board computers, and certification issues. An EU-Japan collaborative research project, VISION (Validation of Integrated Safety-enhanced Intelligent flight cONtrol) has the objective of investigating, developing, and above all, flight-validating such advanced aircraft GN&C solutions.   

VISION project is tackling two different types of fault scenarios, focusing on final approach and landing, which is the most critical operation phase:

  1. Flight control performance recovery from actuator failures (jamming, authority deterioration, etc.) and sensor faults (loss of airspeed data, etc.)
  2. Navigation and guidance performance recovery from sensor faults (e.g. the lack of SBAS in a GNSS-based approach, inaccurate ILS in IFR approach, etc.) and the sudden emergence of unexpected obstacles.

These two scenarios are completely different in nature and so require different approaches. While the first recovery scenario has been tackled by applying Fault Detection and Diagnosis/Isolation (FDD/FDI), and Fault Tolerant Control (FTC) techniques, the second one will be addressed by proposing precision navigation and approach guidance systems using new onboard visual-sensing technologies. The VISION project seeks to make a significant improvement in terms of maturation of the Technology Readiness Levels (TRLs) of these advanced technologies by means of flight experiments on real aircraft.

The VISION project involves six European partners (ONERA and Dassault Aviation in France, Universities of Exeter and of Bristol in UK, SZTAKI in Hungary, and USOL in Spain) and five Japanese partners (University of Tokyo, the Japan Aerospace Exploration Agency (JAXA), RICOH Co. Ltd., Electric Navigation Research Institute (ENRI), and Mitsubishi Space Software Co. Ltd.) from academia, research institutes and industry.

This EU-Japan joint final workshop will present the findings and achievements of the project. It will also provide an opportunity to make scientific/technical exchanges between the VISION consortium and external experts and researchers in the related domains.
