inadvertent stall or spin while performing tasks that are secondary to controlling the aircraft. 102. WING CONTAMINATION EFFECTS ON STALL WARNING, STALL SPEED, AND POSTSTALL RECOVERY. Stall speeds and stall characteristics are usually determined with uncontaminated airfoils. For airplanes that ... alteration of the leading edge caused by factors such as mud, insect residue, or ice can significantly alter the aerodynamic characteristics of the wing, but it is icing that is of primary concern…

CHAPTER 1. GROUND TRAINING: STALL AND SPIN AWARENESS › 100. STALL/SPIN EFFECTS AND DEFINITIONS
achieved in a timely and appropriate manner by reducing the AOA, a secondary stall and/or a spin may result. All spins are preceded by a stall on at least part of the wing. The angle of the relative wind ... also considered. The speed at which the critical angle of the relative wind is exceeded is the stall speed. Stall speeds are listed in the Airplane Flight Manual (AFM) or the pilot’s operating handbook (POH) and pertain to certain…
