Well, except, you can't idle with SPS until touchdown (at down to 260). Dragchute can be released safely anywhere under 320, after touchdown - releasing in midair is proceeded one meter above RWY max, max speed 320.
But as it seems, elevator stops working at too high speeds, it might be able to fly the 190 with elevator working at slow speeds, just saying.
Which kind of reminds me - is SPS working on MF/Bis + when the 0-25-40 flaps will return?
EDIT: Well, my apologies Vega. I've found one interesting thing - landing speed / AoA table shows values for plane weight of 6250 - 7500 kg, where 260 km/h goes for 6250 kg. And I was landing with more than 9000! (Plane full of fuel + PTB) I prolongered the lines and... minimum landing speed, with AoA of 13° would be... 300... -.-' So I will run some tests with almost dry plane as well, to see how close we are.
Also, minimum speed without blown flaps is 300 (at 6250 kg).
My apologies once again.
