Fin tool help

Can someone explain to me the Fin Tool? I have been looking for tutorials online but I can’t find any.

My main problems are understanding wind (does it change direction? And how often?), the Thermal Cli-comething (last check box) and Plane Dynamics, and the difference between lift by plan, no lift and Bernoulli (I know Bernoulli’s force, I’m a physics major, but in-game I don’t see the difference between it and the lift by plane).

Bump.

No Fin Tool experts here?

double bump.

I guess that’s a no?
