The Trident in fact had an all flying tail, the column commanded the whole tailplane and what appears to be an elevator was in fact a geared tab, albeit quite a large one. So the pitch trim did not...

No, they probably didn't, but the point is that they didn't need to. Continued forward pressure on the side stick would have been enough. Completely different to the many 737 LOC-Is (and some non FBW...

TU 154 Heavy??

How odd that the crew should add 'Heavy' in their ATC comms. The lower band of the ICAO Heavy category is 136t so what did they mean as the 154's MTOW is around 100t isn't it?

Is Overload the problem?

Assuming an overload of 12t, Kulverstukas's table (post 246) would suggest Vref(0) should be 24 km/hr higher, call it even 30 km/hr or 15 kt. But presumably (?) Vref = about 1.3 Vstall, so the stall...

Does the Tu154 have a speed baulk or any other device to prevent retraction of the slats at too low speed?

But by all accounts the first signs of alarm from the crew came after the gear up call (if that's what it was), so unlikely they actually started in an unsafe config.
