AP Engaged Causes Oscillation

[Tripdog87]

Hi all,

After several flights I am noticing a trend where during the climb out, with the airplane trimmed to corresponding FD as soon as I engaged AP the A/C wants pitch down abruptly in a slight oscillating motion. I have hand flown the A/C at various altitudes and it is truly a breeze to fly manually but as I said as soon as I try to engaged AP she wants to have an "attitude" with me LOL... Has anyone else experienced this? 😎

I’ve also noticed a sharp downward pitch of 2-3 degrees before the autopilot can get her under control.

I personally haven't seen that yet, no. Could you maybe record a video of this happening having the FCTL page open on the ECAM?
