### Introduction to the Topic of Article  
With the dynamic development of aviation, the global demand for highly qualified pilots is constantly growing. However, increasing the number of flight schools and intensifying pilot training inherently leads to greater consumption of natural resources and an increase in greenhouse gas emissions associated with training flights. Targeting net zero emissions by 2050, international aviation agencies are pushing to reduce emissions directly at their source [1, 2, 3]. In the face of growing challenges related to climate change and environmental protection, the use of flight simulators can be treated as a prospective solution, capable not only of increasing the effectiveness of aviation training, but also of significantly reducing the environmental impact associated with this process. The inclusion of flight simulators in aviation training programs proved to be a revolutionary approach from the very beginning [4, 5]. The advantages of using them were immediately identified: greater training opportunities and lower cost than an hour of flight. Over time, significant ecological benefits have also been seen. When analyzing the literature sources related to the subject discussed in the article, several articles can be found concerning the reduction of emissions from air transport and introducing alternative power sources, including the use of electric aircraft [6, 7, 8, 9] Literature dealing with Flight Simulation Training Devices(FSTD) and their impact on the environment and training is still very scarce and has only emerged in the recent years. In literature, studies can be found that describe training programs and the use of different types of simulators [10; 11; 12; 13]. However, there is a lack of articles directly related to the subject discussed in this article. The authors believe that emphasizing the impact of using FSTD on energy consumption and emissions during pilot training and presenting quantitative analyses will indicate how important it is to use this type of device and suggest expanding their use. This may have an impact on the recommendations formulated in legal sources and regulations. This article attempts to analyze the ecological benefits of implementing flight simulation training devices in the aviation training process. By synthesizing available scientific research, empirical data, and presenting an analysis of energy consumption and emission in different flight simulator use scenarios, this article aims to examine the environmental impacts of simulator training compared to traditional airborne training methods. The primary goal of this analysis is to show how flight simulators can contribute to reducing greenhouse gas emissions and fuel consumption generated by training flights. The additional aim of the research is to compare different scenarios of FSTD use to check which one will be the most advantageous in terms of energy consumption, emissions, and training. By exploring these issues, this article aims to highlight the importance of simulation piloting as a strategic tool to support aviation sustainability goals. In the context of global efforts to reduce climate change and protect the environment, understanding the ecological benefits of implementing flight simulators is extremely important for the future of flight training and the long-term sustainability of the aviation industry [14; 15; 16; 17]. By synthesizing existing knowledge and presenting practical implications, this article contributes to the discussion on the role of flight simulator training as a key element of aviation environmental footprint reduction strategies.
