After doing some additional testing off-line. I believe there is an issue with the following settings.
GroundAutoLethality[Armored]
GroundAutoLethality[Hard]
GroundAutoLethality[Soft]
If you look at the image below you'll see that the GroundAutoLethality[Armored] and [Soft] are at the maximum setting, with GroundAutoLethality[Hard] set to it's lowest level. I was able to fly within the ack for over 10 minutes without sustaining any damage. I flew in the puffy ack for several minutes before descending to low altitude to ensure that both the puffy ack, and small[Soft] guns could score hits.
Per my phone call, I repeated the test after destroying both the auto armored and auto hard guns. and then set the [Soft] lethality to 100 with [Armored] and [Hard] set to .001. I was able to fly in the ack taking several hit without any damage occurring for several minutes.
By a process of elimination and several additional tests, I now believe that all auto ack gun's (TG's, Airfields, and Strat's) lethality is tied to only the GroundAutoLethality[Hard] setting.
