The main objective of this final degree project is to enhance the maturity level of the trajectory simulation software suite developed by the Icarus UPC research group. Consequently, the advancements made in this project aim to adapt the software to provide a more realistic interpretation of the simulation scenarios and, therefore, yield more accurate and faithful results, compliant with real flight operations. To accomplish this objective, the planning and design of a novel functionality are undertaken. This report begins by describing the conception of the implementation within an aeronautical context, thereby establishing the guidelines to fulfill the requirements of the software upgrade. Additionally, the report provides a comprehensive outline of the implementation's architecture, along with a detailed explanation of the operational aspects of the various logical blocks that conform the functionality. This initial section of the report further describes the integration of this implementation within the main software architecture. Afterwards, this report provides details regarding the verification process conducted to ensure the proper operation of the logic. This process encompasses the planning of a particularly interesting scenario, comprising various sub-cases in which the implementation is thoroughly tested. Moreover, the results produced by the software are meticulously analyzed and conclusions about the applied logic are drawn. In addition to the previous verification, another validation process of a more realistic situation is presented. This procedure allows for a meticulous examination of the system's performance and effectiveness within a real-world application scenario. Finally, the results are subjected to an in-depth analysis. This detailed study provides a deeper understanding of the outcomes, yielding valuable insights and potential improvements for the future development of the software
