September 2025 monthly summary for ArduPilot/ardupilot focusing on code cleanup and risk reduction. Removed an outdated PSC_ACC_XY_FILT parameter reference in AC_PosControl.cpp to address issue #31184. No new functionality introduced; existing behavior preserved. This work improves maintainability and reduces configuration confusion.

April 2025 — ArduPilot/ardupilot monthly summary: Key features delivered include the Loweheiser generator build option added to build_options.py to enable the new generator type and Plane takeoff rotation handling improvements with an added rotation_complete flag in ArduPlane auto_state, along with autotest enhancements that strengthen takeoff validation including a level-off wind-condition test. Major bugs fixed include improved takeoff sequence reliability by gating pre-rotation pitch calculations behind rotation_complete and robustness improvements to the Plane.TakeoffGround autotest. Overall impact: increased configurability, reliability, and test coverage, expanded hardware compatibility with the Loweheiser generator option, and reduced regression risk in critical flight phases. Technologies/skills demonstrated: Python-based build configuration changes, embedded flight-control logic updates in the ArduPilot stack, and expanded automated testing/validation."

March 2025 performance summary for ArduPilot/ardupilot: Delivered cross-module Loweheiser generator integration and expanded autotest coverage; fixed critical flight-state and UX issues; improved testing and reliability. Key items include Loweheiser generator support across AP_BattMonitor, AP_EFI, AP_Generator, GCS_MAVLink, and RC_Channel with end-to-end state management and tests; TerrainMissionInterrupt autotest to validate terrain-following transitions GUIDED→AUTO and resume; EFI HALO6000 airborne state fix ensuring the engine is correctly interpreted as airborne to enable power production; AC_Fence error messages clarified to reflect actual logical conditions, improving user feedback.
