I was flying from EDDF TO LIRF AT FL380; This is how i prepar my flight (for a complete test):
1) i have a pre-saved flight on EDDF airport as the default airbus product (engine running ready for take off)
2) once loaded from Prepard 3d I change time of flight and then I select Cold and Dark state panel.
3) I wait 2 minutes waiting everithing is off till engine sounds go off then I power up the airbus.
Maybe not but I think that testing from saved flights is different from direct loading aircraft.
If you check you will also notice that during the flight control check the ailernos will not deploy fully
thank you very much
