The development of flight simulator has huge impact on modern aviation society to support its safety and training process. Other than certified flight simulator, there are gaming simulators such as Microsoft Flight Simulator (MSFS) and X-Plane. By comparing the simulation data of MSFS with Aircraft Flight Manual (AFM), the official document by manufactures, we will see the possibility of gaming simulator and its weakness. From the experiment, we discussed several assumptions which cause the unrealism of MSFS for further researches. This whole project aims to people who are willing to use flight simulator regardless their level of professions. By improving the integrity and capability of flight simulator, everyone can learn how to fly the aircraft in most effective way.
