The description of Parma Magica, and the many examples, show that magically propelled substances (in this case, the air) touch the target, but not with any force, unless it penetrates the parma.
Wings of the Soaring Wind is a touch range spell, which I assume means the maga affects the air that is touching her, causing it to fly her around. We also know that suppressing your parma requires concentration, and is impossible if unconscious. I don't know where I heard this, but I believe your parma works against your own spells, unless they are personal range (which Wings, if I'm reading correctly, cannot be - you are not the air).
RAW, does this mean that Wings can only be used by
penetrating your own Parma (tricky, if you have the auram to cast Wings)
suppressing your parma (requires concentration, as does the spell; losing either dumps you on the ground).
Not casting parma (do mages ever do this)?
So, to summarize:
Does this spell work in some special way, or are the above fixes necessary?
(Assuming the spell is broken RAW,) Can the spell be storyguided into reasonableness?
