For giggles, I wanted to see the relationship (in the DCS A-10C), between weight, G loading and AoA.
I recorded 2 tracks. Test #1 was at aircraft max weight, test #2 was at minimum aircraft weight.
Both flights start at 25k. I attempted (as best I could), to maintain barber pole while in a descending spiral, and at the same time pulling to and maintaining the steady tone. (manual says the steady tone comes on within 2 angle of attack units of stall)
I accelerated while in the spiral following the barber pole and continued increasing the G loading to just shy of the chopped tone. Then I replayed the tracks pausing every 1k feet and recording the IAS, AoA and G loading. I did this at max and min weights. Here below are the results:

Formatting screwed up in the forum. See the post below with word doc and results in proper format.
Notes:
1. IAS was read from the cockpit steam gauge. Alt, AoA and G were read from the F2 page.
2. See the attached track files. test 1 max wt spiral @ barber pole, maintaining max sustained G @ stdy tone.trk test 2 min wt spiral @ barber pole, maintaining max sustained G @ stdy tone.trk
