- Joystick is deflected “out of trim”, against centering springs;
- Trim button is depressed and released. FlightGear temporarily ignores movement of joystick (roll, pitch, yaw axes);
- Joystick is relaxed to it’s center position;
- FlightGear plays "click" sound and starts "listening" to joystick input again. The helicopter is now in trim and flight can be continued with relaxed controls.
