[Fig- ure 2-26] The pilot can add weight or increase loads which may  also increase the angle of attack slightly.  The  flare (pulling down the trailing edges of the  wing—and thus lowering the trailing edge) increases  the angle of attack. [Figure 2-27] In a flare, the trail - ing edges of the wing are pulled down (usually, as  both foot steering controls are pushed forward). This  is similar to lowering the flaps on an airplane: lift is  increased, drag is increased, and for a PPC, the angle  of attack is increased. The result is that the higher drag  wing slows down and thus the wing moves backward  relative to the cart. So as the total weight of the pen - dulum (the cart and occupants) moves forward of the  wing, the angle of attack increases, generating more  lift and more drag. The pendulum is the weight of the  CG under the wing which swings forward for this  transient situation due to pendulum effect. Note that flare provides a temporary large increase in  the angle of attack (AOA) until the pendulum swings  back underneath the wing. This action thus returns the  wing to the normal stable flight configuration — the  cart (the total weight of the pendulum) under the cen- ter of the wing. Therefore, a flare will only temporari - ly add an increase to lift and drag. Once the pendulum  swings back down, the drag of the wing, and therefore  the reduced airspeed, will continue until the flare is  released. 2-13 Flaring Increases Angle of Attack
