Elliot Rosemeyer focused on enhancing the flybywiresim/aircraft repository by addressing a critical bug in the Flight Control Unit’s altitude selector. Using C++ within an embedded systems context, Elliot fixed the incorrect rounding behavior when the 1000ft interval knob was selected, ensuring that altitude adjustments in the flight simulator became more precise and intuitive. The solution involved targeted code changes and validation through specific tests, which were then integrated into the mainline for the March 2025 release. This work improved the simulator’s accuracy and user experience, demonstrating Elliot’s attention to detail and proficiency in flight simulation and C++ development.
