Wing Control: Flaps, slats, and ailerons change the chord line, impacting lift and control. In general, the chord line is used as an easy-to-understand reference when referring to the properties of a wing or airfoil. The mean camber line is drawn halfway between the upper and lower surfaces. What Is the Chord Line in Aviation?

Use of Reflex Airfoils Ever notice how many tailless aircraft have wings that curve at the trailing edge? This type of design is a reflex airfoil. The reflexed shape of the airfoil usually causes a positive (nose-up) pitching moment coefficient at its aerodynamic center. They combine the functions of elevators and ailerons.

They are designed with a special shape called an airfoil, which encourages passing air to turn and deflect downward. One is the upper wing surfaces curvature compared to the lower surface, called wing camber. High camber generally promotes more airflow deflection, thanks to something called Bernoullis Principle.
