    Induced drag is drag associated with the production of lift, so, adding flaps and increasing the angle of attack would increase lift but also increase induced drag.

  3. 3) Wingtip vortices are created when _______ air ________ the wing spills over into the ________ air ________ the wing creating a vortex. These are created on ________.

    Wingtip vortices are created when high-pressure air from beneath the wing spills over into the low-pressure air above the wing. All aircraft, large/small, light/heavy, create some form of wingtip vortices when the airfoil is producing lift.

  5. 5) Ground effect is associated with a ________ in performance due to reduced _________. This causes drag to _______ and vertical lift to _______.

    When entering ground effect, you get an overall increase in performance due to the reduction in downwash/wingtip vortices which causes induced drag to decrease and vertical lift to increase.
