InFlight_Automatic_Determination_of_TECS_Parameters

English Video S1 (InFlight_Automatic_Determination_of_TECS_Parameters) provides a representative real-flight demonstration of the method presented in the manuscript “Experimental Validation of a Stepwise Automatic Determination Method for TECS Parameters in ArduPilot Based on Steady-State Assessment.” The method is implemented as a Lua script for ArduPilot Plane (v4.6) and performs stepwise automatic determination of TECS parameters by monitoring flight-state variables and detecting quasi-steady time intervals under predefined flight conditions. The procedure is managed as a sequence of phases (e.g., acceleration/deceleration, steady climb, and steady descent), and TECS-related longitudinal control parameters are updated when steady-state conditions are satisfied. This video is provided to help readers understand (i) the overall phase progression; (ii) the aircraft behavior during each phase; and (iii) the timing at which parameter updates are triggered during the flight.
