The term 'angle of attack' is defined as the angle between the airplane's longitudinal axis and that of the air striking the airfoil. Air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface. The four forces acting on an airplane in flight are lift, weight, thrust, and drag.

The Four Forces of Flight (Lift, Thrust, Drag & Gravity) obey Newton’s Three Laws of Motion. irplane controls work per the Lever Principle, and a wing’s airfoil shape increases lift via the Bernouilli Principle and Coanda Effect. Like Moses and the Ten Commandments, aviation is limited by 10 laws of physics and chemistry.

An angle of attack (AOA) indicator can determine the aerodynamic health of the airfoil (wing). More simply, an AOA indicator displays the margin between the current AOA of the airfoil, and the AOA at which the airfoil will stall (critical AOA), providing the pilot with a visual and sometimes audible indication.

Winging It Aside from the aforementioned desire for a greater aspect ratio for reduced drag, the one-piece Gweduck wing was developed for minimal weight, ease of construction and benign handling. Keeping drag corralled was emphasized as the Gweduck mission is foremost long-distance cruising.
