I know that this level of smoothness can be achieved in wings and tails on sailplanes and powerplanes that are filled with dry micro and then carefully profile sanded with long sanding sticks. That means cored composites and maybe plywood skinned stuff too. But in aluminum? Really skeptical... Even if you could build the wing accurate enough and with small enough chordwise waviness, you still have the flexibility of the skin...How could that number get into fabric covered/unfinished composite male mold flying surfaces ?
