飛機維修是航空業的一個非常重要的環節，它影響著航空公司的經營，也深深影響著飛行的安全。改善這一點的最好方法是確保飛機維修的充分培訓。本文建立了一個用於飛機維修培訓的虛擬現實（VR）系統。以多尼爾228飛機為例，在該系統的虛擬環境中進行了飛機的走位檢查、機翼燃油系統的可視化以及水平穩定性拆裝練習。
這個VR系統使用CATIA軟件來生成多尼爾飛機的整個形狀，燃料系統的部件，以及水平穩定器。然後，它將多尼爾飛機的形狀導入Unity軟件，開發飛機維修的虛擬現實技術。使用HTC VIVE作為硬件設備，在虛擬環境中進行飛機維修操作。這個VR系統包括三個不同的場景，在第一個場景中設置虛擬機庫，結合多尼爾飛機對飛機進行走位檢查，仔細檢查飛機部件，熟悉飛機部件的位置。在第二個場景中，用戶可以透過機翼的燃油系統，了解燃油系統的流動情況。最後一個場景是水平安定面的維護程序，我們訓練學生練習拆卸和重新組裝水平安定面。
這個系統可以作為飛機部門的學習工具，也可以通過這個結果作為航空公司的教學材料。另一方面，國際飛機通常在夜間進場維修，培訓時間不容易配合。因此，在實物飛機難以進入的情況下，該系統可以增加新學員的練習機會。此外，在COVID19疫情期間，避免接觸成為主流，這個VR飛機維修系統可以通過避免接觸和自我學習的方法提供一個安全的學習環境。此外，這套VR系統的成果也得到了飛機學員的測試和使用。在使用該系統後，參與的學生完成了一份調查問卷，他們一致認為該系統對他們的學習非常有效，有助於提高飛機維修技能。

Aircraft maintenance is a very important segment of the aviation industry, which affects the operation of airlines and also deeply affects the safety of flights. The best way to improve this is to ensure adequate training in aircraft maintenance. This research established a Virtual Reality (VR) system for aircraft maintenance training. The Dornier 228 aircraft was used as an example to conduct the walk-around checks for the aircraft, visualization of the wing fuel system, and the horizontal stability disassembly/assembly exercises in the virtual environment of this system.
This VR system uses CATIA software to generate the entire shape of Dornier aircraft, components of the fuel system, and the horizontal stabilizer. It then imports the Dornier aircraft shape into Unity software to develop the virtual reality technology for aircraft maintenance. Using HTC VIVE as the hardware equipment to perform aircraft maintenance operations in the virtual environment. This VR system includes three different scenes; setting up a virtual hangar, combining the Dornier aircraft to carry out a walk-around check for the plane, carefully inspecting the aircraft components, and familiarizing with the aircraft parts' location in the first scene. In the second scene, users can see through the wing fuel system to understand the flow of the fuel system. The last scene is the maintenance procedure of the horizontal stabilizer, students were trained to practice disassembling and reassembling the horizontal stabilizer.
This system can be used as a learning tool for the aircraft department and teaching material for airlines through the result. On the other side, international planes usually enter the field for maintenance at night, and it is not easy to match the training time. Therefore, in the case of difficult access to physical planes, this system can increase the opportunity for new students to practice. Furthermore, contact avoidance became mainstream during the COVID19 epidemic, and this VR aircraft maintenance system can provide a safe learning environment by avoiding contact and self-learning methods. In addition, the results of this VR system were tested and used by the aircraft students. After using the system, the participating students completed a questionnaire and agreed that it is highly effective for their learning and helps improve aircraft maintenance skills.
