Do inboard high-speed ailerons help with the roll control by decreasing the moment arm as a secondary benefit? As in make it harder to exceed the roll limits when at high-speed.
I know the main benefit is to avoid aileron reversal. Also I'm aware discussing tailoring the stick forces in depth will be too broad. So I'm not after an in-depth analysis. Just if that secondary function is indeed a reason.
Comparison of high-speed aileron placement on Airbus and Boeing is shown below. In an Airbus with fly-by-wire (FBW), the stick commands a roll-rate. And all the Airbus FBW heavies—including the A380—do not feature far-inboard ailerons like the Boeings. In other words, if FBW did not exist, could Airbus have still been able to not have mid-wing ailerons?
