There was common discussion among professional pilots how the ProSimA320 flight model was ‘on rails’ and unrealistic. In comparison the freeware avionics suite Jeehell FMGS provided a more accurate rendering of the flybywire system with a flight model which was similar in depiction to the real aircraft.
This might all change with the soon to release ProSimA320 Flight model.
In the latest ProSimA320 beta, the software is being prepared for a new flight model release and support for the ProSim P3D plug in.
