This flaperon is actually the high speed aileron. Using the outer ailerons at high speed will twist the wing, which in turn reduces their effectiveness. For every aileron there exists a speed where it becomes ineffective and above that speed its function will even be reversed. See the flexible wing as a flap in its own and the aileron as its Flettner tab of ...

Only simple flaps can be flaperons. Fowler and double-slotted flaps generally used on large aircraft cannot move upward, and are designed to extend slowly, which is more appropriate for their complexity and fairly large effect. But that's opposite of what you need in aileron, which must react quickly and using bigger deflection up than down is desirable to ...

The upper wing of the Fokker Dr.I is larger in span and chord than the other two. Adding ailerons on the lower wings would had
added less effect for additional mechanical complexity,
and on the lower wing they would be subject to damage upon ground contact.
I know that it is hard to argue here that ailerons must be protected from ground contact, but this ...
