    • PURPOSE: A real-time stability test method is provided to safely measure stability during flight in real time without opening a control loop during the flight by recording and calculating data without an aerodynamic model or a structure dynamic model. CONSTITUTION: A real-time stability test method comprises a preprocessing step in which an input device is connected; a step (S1) of collecting data in real time with a data pump by building the data pump; a step (S2) of calculating a closed loop transmission function and an open loop transmission function by converting the collected data; a step (S4) of calculating margin based on the open loop transmission function; a step (S5) of calculating phase margin based on the open loop transmission function; a step; and steps (S3,S6) of calculating the open loop transmission function with the closed loop transmission function when input of an actuator side is not measured. The real-time stability test method is comprised between a flight control computer and an actuator for a test.
