How Do You Calculate Lift Force on a Banked Airplane?

[Visual1Up]

Need some suggestions...

I have a banked airplane at theta degrees, with a radius, and velocity. What is the formula for finding lift force. Fc = Fn sin theta I believe, but that's the only formula I am aware of. Thanks!,

The plane has centripetal acceleration in the horizontal direction. The pilot keeps the plane banked at just the right angle to keep the plane from slipping and maintain a steady altitude. Which forces, and which components of those forces, are keeping the plane from moving up or down?
