隨著全球航空產業蓬勃發展,為了確保飛機能安全起降,飛機修護的人力需求也逐年增加,所以需要培訓大量的飛機修護的人力。又,航太科技相關的教學實習器材昂貴而不易普及,導致學校等訓練單位難以提供妥善的電路系統做為教育訓練之用,使訓練成效不佳及延長受訓時程,造成人力及物力資源浪費。With the vigorous development of the global aviation industry, in order to ensure that aircraft can take off and land safely, the manpower demand for aircraft maintenance has also increased year by year, so it is necessary to train a large amount of manpower for aircraft maintenance. In addition, the teaching practice equipment related to aerospace technology is expensive and not easy to popularize, which makes it difficult for schools and other training units to provide proper circuit systems for education and training. This makes training less effective and prolongs training time, resulting in waste of human and material resources. .
