Madara's Gunbai doesn't help, you need an ultrafocused wind style attack to pierce his armor. His fan can't do that as far as we know.

Also it depends on how much each of them knows going into the fight. I'm going to give Madara the benefit of the doubt and allow Susanoo's rib cage and arms, since Sasuke could manifest those with his MS. But Madara doesn't pull out Susanoo until he's forced to. If he doesn't realize at first just how dangerous his opponent is, A could land a serious blow before he can form it. Similarly, if A doesn't know he's fighting an Uchiha and what that means, it's potentially game over once he looks into Madara's eyes. Both scenarios are debatable IMO, Madara's been known to form Susanoo pretty fast and even if A is caught in a genjutsu, what then? If his Lightning Armor is active Madara most probably wouldn't be able to finish him off before he can break out of it.

If they go in with prior knowledge I'm pretty sure Madara would activate as much of Susanoo as he can at once and try to stay out of reach, and A is fast enough that he could avoid eye contact as much as possible. As far as chakra goes, A has wrestled Gyuki to a standstill and fought ten thousand men on his own - on the other hand, the MS would be a constant drain on Madara (Sasuke's a transmigrant too and he tired out pretty quickly). Also if their fight drags on too long there's the possibility that Madara would go blind.
