There is actually a doc about filters in FlightGear documentation. Filters can be applied on input or output values, in other words, before and after the PID controller (execution). | There is actually a doc about filters in FlightGear documentation.

To tune a controller you would typically display the setpoint property and the controlled property in the same graph. Another property that is interesting too look at is the actuating property, which can be for example the aileron control or the elevator control. | To tune a controller you would typically display the setpoint property and the controlled property in the same graph.
