"4300m from runway threshold would require app. 220kph average speed which seems much more applicable for the stall scenario. I conclude we talk about 70 seconds time when airborne excluding t/o run."
Thanks Pali. But 220 kph is only about 110 kt (ground speed). Not sure that would be sustainable as an average from airborne, assuming little headwind. I don't know the Tu 154, but I imagine the Vr would have been considerably greater than that?
