Although the sim is amazing, it's not perfect. We still have hydraulics with an only windmilling engine, even though the 1A-10A-1 and the real checklists show that it's incorrect behaviour. Let me reiterate having inconsistencies and incorrect behaviours is perfectly fine, it's simply matter of acknowledging the issue.
Multiple proof was posted some time ago. Latest I heard was from a go someone had on the real A-10 USAF sim.
Didn't real contracts call for 775 ITT during climbs? We can hardly reach that value in DCS at MAX power. Either ITT has two different meanings in the sim and IRL, the real contracts are wrong, or something is amiss with the engines and their behaviour.
e.g. From the 1A-10A-1, Cold Weather Operation:
I've never seen 865°C ITT ever in the gauges.
From the 1A-10A-1, Sample Inflight Data Log Hi-Lo-Hi Combat Mission:
And 775°C ITT can't be MAX power (which is around what we get at MAX in the sim if memory serves) since again from 1A-10A-1, Combat Performance Charts (General):
Implying 775°C ITT isn't from a MAX thrust power setting.
