    difficulty in recovering from a stalled condition. (An aft CG means that the CG will be closer to the center of lift (or center of pressure), which in turns means that the aircraft will be less controllable, so more difficult to recover from a stall.

    chord line of the wing and the relative wind. 

    (This is rote memory material. The angle of attack is always defined as the difference between the chord line and the relative wind. The chord line is the line between the leading edge and the trailing edge of the wing. The relative wind is the vector that represents where the airflow that “hits” the wing is coming from. The relative wind is always parallel to the direction of motion of the aircraft, but opposite in direction. See “Stalls” video for more information.)
