This paper presents the steps that must be taken to develop a Simulator type software using VR technology and the presentation of our own software system for the training aviation personnel. We present the state of the art of VR and describe the developed application through the chosen solution, meeting all the criteria of a learning and testing environment for the aviation personnel, simulating the targeting operations of a helicopter and adjacent elements. In fact, we make a description of both the data structure and the technical design. Logical design and system architecture, use cases and conceptual classes are also presented. The technical part describes in detail the implementation stages of the application.
