Control surface angular range

Good evening all.

I have some questions regarding control surface movement ranges. This is for a flight simulation that I am making using the free Flightgear simulation program.

1. Does anyone know the range of movement of the elevator, aileron and rudder?
2. Do the autopilot and yaw damper have full control authority? I understand that the artificial feel system will provide effective limits at high speed.
3. What is the range of aileron and rudder trim?

The Pilot´s Notes give the tailplane trim range and some numbers for aileron upset.

A couple of images for you:

I haven't found a number for the rudder trim range. This is a function of the feel unit and I'm not sure if the actual trim range is mentioned somewhere. A Yaw Damper test mentions that the rudder should move through its full range, I cannot find any limits in the autopilot chapter either so I would say that they both have full control authority, apart from any limits internal to the autopilot/YD programming or imparted by the feel unit.

Many thanks - another problem solved ;)
