Explain how an aircraft turns.

Explanation should include the following concepts:

• If an aircraft in straight-and-level flight were viewed from the front, and if the forces acting on the aircraft could be seen, lift and weight would be two apparent forces.
• If the aircraft were in a bank, it would be apparent that lift did not act directly opposite to the weight; rather, it now acts in the direction of the bank.
• When the aircraft banks, lift acts inward toward the center of the turn, perpendicular to the lateral axis, as well as upward.
