do have some attitude hold in xml defined. I tried a little bit, but Rollrate command 
seems
to work better... I have some troubles getting the right factor for elevator position 
esp. in
Approach :)) (at low IAS)
Does anyone know where to debug die fcs values of my on functions defined as componets 
in A/C .xml file?
I need some values to trigger the right factors for flight controls.
