Hello everyone, I'm trying to develop a fairly realistic flight model. But I can not solve a problem: I would like to calculate the 'angle of the velocity vector (eg z) and ' corner 's plane. I tried to do a lot of evidence and are still more than a month here, and I have a mess on his head! Thanks in advance ....

Tanks anyway! ....more precisely: I need calculate the angle from my Z (Vector of the Airplane) to Vector velocity of this. (To simulate the wind).
The problem is the vector of velocity, not the calculation of the angle.
