The Sustained Stall, or Falling Leaf Exercise, is not unique to APS. This exercise is a great opportunity for the student to observe and experience flight beyond the normal envelope at angles of attack greater than the critical angle of attack. In addition to simply getting the student’s feet moving, the Sustained Stall Exercise is an excellent demonstration of the aerodynamic reality of negative roll damping, exponential drag affects and reverse aileron effect. The awareness of and first-hand experience with negative roll damping is important to the avoidance, understanding and recovery from the various stall conditions, specifically uncoordinated traffic pattern stalls. This excercise clearly demonstrates the four characteristics of a stall seen in fixed wing aircraft: buffeting, lack of pitch authority, lack of roll control, and an inability to arrest the rate of descent.
