Human factors in flight test workshop

01 October 2025 13:00 - 13:20

Flight test often involves the evaluation of new design concepts, novel propulsion systems, controls and displays. Understanding human interactions within this high-risk environment is critical for safe outcomes. Human factors is the scientific discipline concerned with the understanding of these interactions by applying principles, tools and methods to improve performance, safety and usability.
This workshop introduces the Human Factors Analysis and Classification System (HFACS) for accident/incident analysis (and prevention). The method used by many global organisations including AAIB, FAA and others, provides insight into safety vulnerabilities in highly technical and complex environments such as flight test. The method is further demonstrated by example using a recent accident case study involving an electrically powered aircraft. During flight testing under UK CAA experimental flight rules, the experimental aircraft suddenly lost power whilst in the circuit/pattern. The two-person crew took 9 seconds to identify the failed system and attempt recovery actions. These were unsuccessful and the pilot landed in a field adjacent to the airport resulting in severe damage to the aircraft. HFACs was used to identify causal/contributory factors and highlight key learning points. The results informed changes to UK CAA experimental flight rules related to flight test organisation, use of system controls, positioning of displays and the availability of alerts and warnings.
Following the case study, participants will be given the opportunity to apply HFACS to an unseen accident with guidance and supported from the presenter. Results will be shared and discussed with attendees at the end in an interactive session.
