Wind Wall: Small character on a medium flying mount

[Forty2]

What happens when a Small character riding a Medium flying mount attempts to move through a Wind Wall? Nothing? Rider blown off the saddle? Fly checks?

Judging from the High Winds table under the Fly Skill, a Wind Wall seems to fit the bill for Windstorm-strength winds. (Both blow away Small flying creatures) However, I wouldn't be asking the Rules Forum if I was certain.

I would say the small rider would likely need a DC 5 Ride check to stay in the saddle. Obviously any modifiers that apply would help. +2 for having a military saddle, -5 for riding a mount bareback, -5 for riding an ill-suited mount (like maybe you trying to ride your medium-sized flying friend to bypass the wind wall).
