Ailerons deflection of the F16 in take off and landing gain?
As per flight control diagram from General Electric 1975:
The aileron control can command +/-21.5 degs.
The flap control can command +21.5 degs down (even though the HUD will say 20 but there is in this control a +1.5 electrical bias which will be neutralized by the mechanical bias). This is added to the aileron control output.
Then one should subtract the 1.5 degs mechanical flaperon bias.
The flaperons can move +20 to -23. (remember negative is up)
So one flaperon will be at +20 down while the other will be at -1.5 up above the cord given that the aileron produces max aileron roll.
So the question is will the aileron control command max deflection if you are airborne? Most likely no when the aircraft starts rolling, as when the gear is commanded down, internally in the roll system the command will be decreased due to roll rate, and the command is only about half with gears down.
But when you are weight on wheels and the roll rate is zero, you will get one of them 1.5 degs above the cord line, when you command max roll.
