During December 2025, Lachlan focused on enhancing engine control robustness in the ArduPilot/ardupilot repository. He addressed a critical issue in the Engine Idle Governor by ensuring initialization occurs at the configured start percent rather than the minimum throttle, which improved idle accuracy on first run and during engine state transitions. His work involved in-depth validation of the idle control path to reduce startup drift and increase reliability of state changes. Utilizing C++ programming within embedded systems and engine control systems, Lachlan’s targeted bug fix contributed to safer and more stable autopilot performance, demonstrating careful attention to system initialization and operational correctness.
