What problem could ground effect cause during takeoff? An overloaded or improperly configured airplane may take off and fly, but be incapable of climbing out of ground effect. What is the angle of attack? The angle between the relative wind and the chord line of an airfoil. Which statement accurately describes the lift-to-drag (L/D) ratio? L/D varies with angle of attack. How can pilots increase the amount of lift during flight? Increase airspeed Which of the following best describes critical angle of attack? The angle of attack that, if exceeded, causes the airplane to stall regardless of its airspeed, flight attitude, or weight.
