Indeed, if the relative wind is down the angle, the smoke will be parallel out to starboard of the approach path and hence not a problem. However, in low or nil wind conditions, when it isn't possible to have the relative wind down the angle, the smoke (and there tends to be a lot more of it in low wind conditions since the ship is going b*lls out to give sufficient wind over the deck) will stream directly aft. Since you're approaching along the angle, you have to fly through the smoke; this gives a bit of turbulence, and it's occasionally possible to lose sight of the deck and mirror altogether for a brief period.
Not a problem with the new electric carriers, though.
