Say the horizontal stab somehow became able to float up and down the screw shaft on its own - would the elevators act as a servo surface like how some aircraft have a smaller flight control surface move opposite the desired deflection of the main surface?
In this hypothetical scenario, pulling back the yolk would cause the horizontal stabilizer to deflect leading edge up. This would cause a dive.
Can anyone attest to the capability of full yolk back (under normal travel limits) to overcome a horizontal stab trimmed all the way leading edge up?
