Hi all,
I find a solution for this.
I redefined my Airbus TCA Throttle setting in the calibration options on the tablet.
Redefined my idle position. As I was setting the idle I was pulled back on both throttle axis slightly at idle without going into reverse. Then Validate. So the ground idle will be a bit higher around 67%NP for me.
The Hydraulic pressure problem occurs when the NP drops below 65% for me.
So now it is raised to 67-70% and the issue is gone.
Hope it will help for someone.
