  • IECON - Vision-Based Aircraft Pose Estimation for UAVs Autonomous Inspection without Fiducial Markers
    IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
    Co-Authors: Dario Cazzato, Miguel A. Olivares-mendez, Jose Luis Sanchez-lopez, Holger Voos
    Abstract:

    The reliability of aircraft inspection is of paramount importance to safety of flights. Continuing Airworthiness of aircraft structures is largely based upon the visual detection of small defects made by trained inspection personnel with expensive, critical and time consuming tasks. At this aim, Unmanned Aerial Vehicles (UAVs) can be used for autonomous inspections, as long as it is possible to localize the target while flying around it and correct the position. This work proposes a solution to detect the airplane pose with regards to the UAVs position while flying autonomously around the airframe at close range for visual inspection tasks. The system works by processing images coming from an RGB camera mounted on board, comparing incoming frames with a database of natural landmarks whose position on the airframe surface is known. The solution has been tested in real UAV flight scenarios, showing its effectiveness in localizing the pose with high precision. The advantages of the proposed methods are of industrial interest since we remove many constraint that are present in the state of the art solutions.

  • A Preliminary Investigation of Maintenance Contributions to Commercial Air Transport Accidents
    Aerospace, 2020
    Co-Authors: Fatima Najeeb Khan, Ayiei Ayiei, John Murray, Glenn Baxter, Graham Wild
    Abstract:

    Aircraft maintenance includes all the tasks needed to ensure an aircraft’s Continuing Airworthiness. Accidents that result from these maintenance activities can be used to assess safety. This research seeks to undertake a preliminary investigation of accidents that have maintenance contributions. An exploratory design was utilized, which commenced with a content analysis of the accidents with maintenance contributions (n = 35) in the official ICAO accident data set (N = 1277), followed by a quantitative ex-post facto study. Results showed that maintenance contributions are involved in 2.8 ± 0.9% of ICAO official accidents. Maintenance accidents were also found to be more likely to have one or more fatalities (20%), compared to all ICAO official accidents (14.7%). The number of accidents with maintenance contributions per year was also found to have reduced over the period of the study; this rate was statistically significantly greater than for all accidents (5%/year, relative to 2%/year). Results showed that aircraft between 10 and 20 years old were most commonly involved in accidents with maintenance contributions, while aircraft older than 18 years were more likely to result in a hull loss, and aircraft older than 34 years were more likely to result in a fatality.

  • Human error classification and management in aviation design - a critical review
    2019
    Co-Authors: Eranga Batuwangala, Graham Wild, Jose Silva
    Abstract:

    Safety management systems (SMSs) are widely applied and regulated in operational environments of aviation, this is less so in aviation design organisations. It is accepted that system safety engineering practices and heavily regulated system certification procedures assure the design, development and production of airworthy aircraft. However, to further improve safety in the context of initial and Continuing Airworthiness, regulations on the implementation of SMSs are moving beyond the operational environments to design organisations. Due to the differences between design environments and operational environments in the aspect of human factors, existing tools to analyse human error may not be directly applicable nor effective in design organisations. This paper examines the processes of a design organisation and provides a classification of human error that affects aviation designs taking into consideration the socio-technical aspects and multidisciplinary stakeholders and teams involved in the design process. It further provides a critical review of existing tools and models for human error analysis and management and evaluates their applicability to design organisations.

  • The Regulatory Framework for Safety Management Systems in Airworthiness Organisations
    Aerospace, 2018
    Co-Authors: Eranga Batuwangala, Jose Silva, Graham Wild
    Abstract:

    In recent years, a growing emphasis on safety has driven various industries, both in manufacturing and service, to implement a Safety Management System (SMS) in their organisations. SMSs have also been widely implemented in aviation due to both regulatory requirements and voluntary implementation with the aim of decreasing incidents and accidents whilst reducing inefficiencies and costs stemming from the repercussions of safety failures. The aviation industry involves various players for the provision of services ranging from airline operations, maintenance, aerodrome operations, air traffic services, aircraft and component design, manufacturing, and training. Not all organisations in the aviation industry have implemented SMSs. Furthermore, SMS is currently not regulated for all aviation organisations. Whilst technology has played a key role in driving down the number of accidents and incidents in aviation, the growth in air traffic demands having programs in place to further drive down accident rates. In this context, this article provides an investigation to the regulatory framework for the implementation of SMSs in aviation, including the requirements stipulated by the International Civil Aviation Organisation (ICAO) and the status of SMS regulation of key National Aviation Authorities (NAA) and Military Aviation Authorities (MAA), with a focus on organisations involved in Airworthiness including initial and Continuing Airworthiness. This article also investigates the challenges of implementing SMSs in organisations involved in Airworthiness, as well as the benefits that could be gained by service providers as well as NAA’s or MAA’s through SMSs.
