Imaginary straight line drawn through an airfoil from the leading to the trailing edge. What is Chamber? The characteristic curve of an airfoil's upper and lower surfaces. What are the Primary Flight Controls? Flight Controls required to safely control an airplane during flight. (Ailerons, Elevators, and Rudder). What Axis do the Ailerons operate around? Control Roll about the Longitudinal Axis. How do the Ailerons Work? Both sides move in Opposite Directions. The upward aileron decreases lift, lowering the wing. The downward aileron increases lift, raising the wing. What is Adverse Yaw? The down deflected aileron produces more lift and thus creates more induced drag. This yaws the nose toward the raised wing. How do you counter Adverse Yaw? Use Rudder to counter and maintain coordinated flight. What are the types of Ailerons that combat adverse yaw? Differential, Frise-Type, Coupled Aileron / Rudder, and Flaperons. What are Differential Ailerons? Upward moving aileron raises higher than the downward moving aileron lowers. The raised aileron then produces more drag helping reduce adverse yaw. What are Frise-Type Ailerons? Raised aileron projects its leading edge into the airflow (Reduces adverse Yaw). Forms a slot so air flows smoothly over the lowered aileron.
