A320 A/P ALT or ALT CRZ mode
Hi,
When in Alt or Alt CRZ mode on the A320, will the A/P regain altitude if it deviated from the alt due to eg. turbulence?
Eg. FL 350, and hit turb and it deviated say -300 ft to fl 347.
Now will it climb back up (with a/p on and no input from pilot) and will there be a mode change? Sounds silly i know but i really don't know. My guess is it "should". Hmm mode change i dont know..

Without specific knowledge of that aircraft autopilot, I would have guess that when should the aircraft diverge from its altitude target:
1/ The A/P would correct it and come back if the disturbance between altitude and altitude target is small enough.
2/ If that difference becomes so important (for whatever reason) that the A/P decides it can not come back to the target altitude, then it would disconnect.
My 2 cents...

Don't forget that in ALT CRZ you will have the soft altitude hold mode where it will allow the plane to "wallow" around the selected altitude buy + or - 50'.
There would be no mode change.
