In one specific hypothetical case, over a given period of time nose high somewhere in that 6-15 degree pitch range, airspeed decaying, if you were to graph a
hands-off 'neutral' sidestick, would that not be a 0 degree deflection integrated over a particular time period (flat line)?
But you would end up with a constantly increasing value of nose up elevator deflection over time attempting to hold the FP which I guess in a way could be considered as 'elevator leading sidestick'.
Now the SS is physically moved nose-up...
The same existing pitch rate (=elevator position) required for airspeed decay and in effect for the flight path is continually input over a range of
increasing SS angles as the deflected elevator holds the FP until the SS
rate command catches up? Would this give the appearance of elevator leading SS?
This may not be what you're getting at.
