Anatomy of the turn:
[ QUOTE ]
The tilted lift vector also has a horizontal component, lift times the sine of the bank angle, which is tending to pull the airplane into the direction of the bank. This pull should result in the airplane just moving sideways, and would, except that the vertical fin provides weathercock stability and thus aligns the longitudinal axis with the resultant motion.

Obviously other situations can change what is turning the aircraft (like slamming the aircraft into a skid with rudder). The point is that the FAA answer of horizontal component of lift is far from a complete answer when describing what makes an airplane turn.
