In general the triggering of AACIs is based on (surprise, surprise) RNG.

They have a chance to trigger which usually ranges between 40% and 65%. In general the better AACIs (more planes shot down and/or higher AA multipliers) have the better rates, for example the duckies equipped with two 10cm Twin High Angle Guns with Anti-Aircraft-Fire-Director (Akiguns) and an Radar have about 65-67% trigger rate. Weaker set-ups or generic equipment combinations like High Angle Gun with a (separate) Anti-Aircraft-Fire-Director and an Air Radar will be worse in any respect, including the trigger chance. The ships that have their own specific AACIs (Akizuki-class, Maya K2, etc.) often have vastly superior trigger rates.

If they trigger, it will be only during the opening air strike where it will provide a buff to the planes shot down. During the shelling phase the AACI will not trigger again, but the shot down planes will of course not participate in either bombing.

One exception are Aerial Battle Nodes (i.e. Node F on 1-6). In this case there will be two attacks by the carriers and each has a separate a chance to trigger the AACI which, in the case of the duckies, often ends with all planes shot down during the second attack.
