Bearfoil;
For a visual, would it be correct do you think to say that the tail was falling faster than the nose?
The following graphic (an adaption of one originally posted by
Tailspin Turtle) should help with the conception. Note that all the speeds are in terms of GS and that the THS angle of incidence is 13° less than the nominal AoA experienced by the wing.
The 13° NU position of the THS will most likely have helped in stabilizing the descent - see
