- Estudo de viabilidade de desenvolvimento de um demonstrador de Realidade Virtual para as operações de servicing sobre a aeronave A-29B Super TucanoPublication . Silva, Brian Fernandes da; Saúde, José Manuel Mota Lourenço da; Teixeira, Luís Carlos Barrigão CostaSince the birth of aviation, the industry has experienced changes on how an airline operator must perform maintenance operations and how new technicians are trained to perform them to ensure the airworthiness of the aircraft, where the reduction of human errors resulting from non-compliance to the stipulated regulations are one of the main concerns. With the surge of new Virtual Reality technologies, EASA Part-147 approved organizations are enabled to incorporate and direct this new knowledge to the training of new EASA Part-66 approved technicians. However, Virtual Reality technologies must only be used and thought of as a complementary training tool, as it does not provide competencies to perform manual actions as welding, drilling, screwing, among others. Virtual Reality allows the trainee to test his theoretical knowledge at any given time without being limited by the availability of real equipment/components necessary to continue his training, without creating the risk of causing any material damage. All the training performed while resorting to the use of Virtual Reality technologies aims to improve knowledge retention, resulting in better approval rates. In this dissertation, a feasibility study and development of a Virtual Reality demonstrator directed to maintenance training for fuel servicing operations over an A-29B Super Tucano aeroplane must be performed, with the reduction of incidents/accidents reports resulting from wrongly performed procedures set as the main goal. The Virtual Reality application was built on a game engine called Unity, where the user can choose from VR hardware currently available or a mouse and keyboard to perform a fueling procedure. For each procedure, there are three modes available, guided, unguided and VR versions. The guided procedure will provide the user with an oriented experience, where no deviation from the maintenance manual for the fuel servicing action chosen can be performed. Each task will be highlighted in the correct order, providing a visual indication of the task to be executed. An exact copy of the Embraer maintenance manual for the designated procedure will also be provided to be used as a checklist. The unguided procedure allows deviation from the maintenance manual and wrong actions are allowed to be performed. However, a score will be given at the end of the procedure to evaluate how accurately the manual was followed. Embraer maintenance manual will be also provided, but with no checklist. Lastly, the VR version will follow the same fundamentals as the guided version. However, the input and output devices used on the previous 2 versions are replaced by an HMD and two handheld controllers.
