Actually, Ack-Ack, gotta disagree with you on that.
Stall limiter, as much as it prevents you from pulling harsh AOA in turns, will also prevent you from pulling harsh AOA to get yourself out of a dive at the last second, as well.
It's like pulling out of a dive with 1 elevator missing with SL on.
Okay, maybe not that bad, but worse than without.
EDIT: I don't mean a terminal dive from 20k. Say you're split S-ing and breaking from a con, or in the middle of a dogfight, find yourself nose down with very little alt left, and need to pull up. SL will kill ya.
Did few tests this afternoon.
Test #1, without stall limiter on, climbed to 15,000ft and leveled out until speed reached 300mph IAS. I then dove vertically and when I hit approximately 425mph IAS, I pulled back on the stick and pulled out of the dive. Controls were sluggish due to the high speed aerodynamic forces but I was easily able to recover from the dive.
Test #2, same setup but with stall limiter on and again, was able to pull out of the dive at 425mph IAS without any difficulties other than experiencing sluggish controls due the same reasons as Test #1.
Test #3, I climbed up to 25,000ft and leveled out until I was 300mph IAS and again dove vertically. Started to enter into a compressability state around 21,000ft when I was reaching close to 400mph IAS and wasn't able to pull out of the dive until I was below 15,000ft and around 450mph IAS. Had to use some positive elevator trim to help recover and had tunnel vision on recovery.
Test #4, set up the same as Test #3, though with Stall Limiter enabled. Entered into compressability around the same altitude and speed as Test #3 and recovery was almost the same though it did take a couple of more notches of positive elevator trim to recover but no black out and recovery was about 800ft more than Test #3.
Test #5, repeat of Test #3's set up but this time I didn't allow myself to enter into a compressability state. Used throttle and rudders to keep speed in check and never exceeded 350mph IAS, recovered from dive at 18,300ft.
Test #6, same as Test #5 but this time with Stall Limiter and again, kept speed in check using throttle and rudders in dive and didn't exceed 350mph IAS. Recovery was the same as Test #5, 18,300ft.
It only seems that Stall Limiter will have an affect on dive recovery if you allow yourself to overspeed in the dive and enter into a state of compression or compressability. If you keep your speed in check and do not enter into a state of compression or compressability, the Stall Limiter does not have a negative affect in dive recovery.
