In reality, the aircraft will NOT flare, no matter what you see in the simulator.
Sim is NOT the real aircraft. No back-trim at 370' is no flare in real life, and both will not occur with single autopilot approaches.
So do not try it, not only is it not approved, there is also a reason for it not being approved😏
I am now on B744 and that is a completely different story 😀
