This topic will be used as a place to discuss and work on the fixes and improvements of the FlightGear Airbus A320 Family.
The A320 Family ,by default comes with big problems in it's FDM. The aircraft is making a very annoying ,and when properly loaded,dangerous pitch-dive movements. That behavior starts after enabling the autopilot. When reaching the desired altitude,instead of just leveling off,the aircraft starts to pitch-dive,slowly loose speed,stall and crash.
The problem becomes much more present ,with increase of the speed and weight.
What I did so far was this:
Changes in elevators settings ,lift and CG.
Elevators and lift ,brought some changes in the aircraft's behavior. The pitch-dive was eliminated,but,the nose was still up more than it should be. That made landing of the aircraft,close to impossible.
Changes in the CG ,eliminated the high nose,but,the drawback was that the take off speed is ridiculous... The only aircraft which responded right to some or all changes,was A320-200....why? I have no clue.
So,I will post the xml of the A320 Family ,A318,319,320 and A321.
I hope this topic will lead to solving of the FDM problems.
Cheers
