Final flight training is not only the key link in flight training, but also the difficulty of training. How to carry out final training in an efficient and scientific way is an important guarantee to improve the training quality. In the past, there were many pain points and problems in flight training, including weather factors, training efficiency and training cost. Therefore, how to improve training efficiency and training quality is the most important topic in the innovation of training mode. The purpose of this paper is to study the application of virtual reality technology in final flight training. Based on the great development of virtual reality technology and its primary application in flight training, this paper expounds the traditional final training mode and its limitations and shortcomings, analyzes the new training mode using virtual reality technology, lists its advantages by comparison, and explores the application and development of virtual reality technology in other fields of flight training in the future. The incorporation of virtual reality technology is a key factor in improving the quality of final flight training. In the future, further exploration of innovative applications of virtual reality technology in flight training can contribute to the advancement and progress of flight training.
