Hi
I have the PSS Airbus Pro for FS9 from Black Box.
I experience very poor climb performance with the 321 even at low weights and high cost index. (struggle to get 500fpm)
FMC is programmed correctly with ZFW etc, trim is set ok, and controllers are calibrated.
Is there a bug in the FDE? The 320s work fine.
Thanks if anyone can help.
