This add-on enhances the scenery of Istanbul Airport (LTFM) for Microsoft Flight Simulator 2024, specifically for users of BeyondATC. It includes fixes for runway hold short positions, improves runway logic, and optimizes routing for external traffic injection systems such as FSLTL and AIG. Users should ensure they have the SceneryTR Istanbul package, as this add-on is designed to improve the realism of taxiway navigation and prevent runway incursions.
