Worked on the flybywiresim/aircraft repository, focusing on refining the Flight Control Unit’s altitude selection logic within a flight simulation environment. Addressed a bug affecting the 1000ft interval knob, where altitude rounding did not behave as expected, by implementing a targeted fix in C++. The solution ensured that altitude adjustments now reflect precise increments, improving both simulator accuracy and user experience. Validated the changes through targeted tests and integrated the fix into the mainline codebase for the March 2025 release. Leveraged expertise in C++ development and embedded systems to deliver a robust solution tailored to flight simulation requirements.
