If what you stated is correct that means aircraft will stall at 205 KTS but with critical engine failed and full power on others it will not stall even at 117KTS. There is no question of flying below Vs, this Vmca could not have been demonstrated may be theoretically derived. As far as my reference to Vmca I have already corrected that to VLS which is definitely 1.23 Vs1g.
