Trying to drag the airplane in at an excessive pitch angle / AoA is asking for trouble. It's one thin to drag a Cessna into a sort field behind the power curve, but large airplanes are not feel airplanes...whether that be "feeling" nosegear extention or "feeling" dragging it in behind the power curve.

That line of thinking really is irrelevant with respect to the Citation pilot holding aft yoke at sub-reverser speeds.

As for making a short field landing, which is somewhat far afield from the topic at hand, one isn't going to shorten the landing distance by "holding off" or keeping the nosewheel flying. Getting the nosewheel on the ground and using maximum braking and reverse, and spoilers are going to shorten the distance. Why you want to introduce short field techniques and short runways to support the idea of flying the nosewheel and experimenting with the airplane are somewhat beyond me...just as you discarded large airplanes and at the same time invoked Mr. Davis' book.

Rather than repeatedly attempting to cloud the issue with irrelevant, incorrect concepts, why not stick to the topic at hand. There's nothing to be gained in a transport category airplane by holding the stick back while slowing to sub-reverser speeds, or by holding the nose off, while landing, or from aerodynamic drag from a raised elevator. Even if one is moving fast enough to hold the nosewheel off, the benefit from such aerodynamic braking is negligible, whereas the lowering the nose decreases AoA, decreases lift, puts weight on the wheels and makes wheel braking and steering effective. End result; there's nothing to be gained by aerodynamic braking unless one has substantial runway and no other choice.

I've flown LR35's without reversers from locations where I could let it roll and save a little brake, while still having runway remaining. However, once the nosewheel was on the ground, applying back elevator wouldn't have helped, and the real slowing power was in the brakes, not in the yoke...and I wouldn't have considered for one moment attempting to stop the airplane from going off the end "with my mind."
