Above Lift ceiling means insufficient lift to remain at specified altitude, including controls, yes?
I apologize if this seems a parse, are we not disabusing a poster of "Levelling Off" when the a/c cannot fly?
Relative to THS: If I command ND, I push the stick to a a percentage of its available travel, and release. The computer commands the elevators to deflect downward, and the a/c starts to ND. I do not have to hold the input, at what time does the THS start to move? I submit the THS did not move at all, to continue to try to establish a G....if so, the Law prohibits recovery simply because the G loading does not meet its parameter? Recovery from Stall means a good deal of sub 1 G..... Can't get there from the wrong side, according to the THS......
I have held back stick beyond the Stall break, (never with trim), intentionally, but I was doing it deliberately, to spin, why would any aircraft trim past the SW, what pilot would, in an airliner?
It is one thing to hold off when the elevators can provide 1G. Then it cranks in to keep the load factor, and well past the elevators authority. So 'super' NU, and a vary strange entry to STALL. Then when negative G is required, it will have none of it? Why would anyone design an aircraft that can fly beyond its elevators to maintain a load? And then stubbornly hold it after the STALL?
