Thaks for all,

Mach trim is mentioned in FCOM without details.

Couldn't observe any, both in auto and manual flights,

Thank you,

strange that the 60 tons speed is 205 like on CFM 320. On PW321 it is 200 just like on IAE 320 and 321.

Thanks again

On A320 I never saw...

For me the it was easy to change to sidestick.
