What lowering the flaps will do, in combination with a lowered AoA, is enable you to generate more lift once you're unstalled, so you'd need to lose less altitude to recover back to a safe flying speed. I don't know, but I'd think that's the reason for flaps selection on some types - to make the recovery better.
Quite so, I was going to say that the lowering of flaps would contain the speed a tad...in some ways it's saying the same thing. However, a lot of candidates - often ones that should have known better - let the speed build up far too much, so I guess training like that would have seen a lot of limiting speeds busted.
We used to train to the push in the real T-tailed airplane (1-11) - there was no choice, we had no sim - and the 20,000 feet
Denti mentioned, was 15,000 for us, (until more experience had been gained by BAe) so no experimenting with flap if the near-stall was from clean.
We went to the shake and a tad of real buffet with flap down, to cover that aspect of training, but did not ever go to the push.
BTW, the push was quite docile - once you got used to the klaxon - and I'm told that we could easily have restrained it...memory fails me, but I think it was about 80lbs
