Quiz: 6 Questions To See How Much You Really Know About Aerodynamics

Give it a shot...


  1. 1) Wing tip vortices are associated with what type of drag?
    Bernal Saborio

    Wing tip vortices create drag that is associated with the production of lift, called induced drag.

  2. 2) In general, which of these wing planforms stall at the tip first, then moves inward toward the root?

    Aleksander Markin

    Because of the design, a tapered wing has the tendency to stall at the wing tip first, with the stall moving inward toward the root.

  3. 3) The point where the parasite drag curve intersects the induced drag curve provides what?

    Because this is the point where total drag is the lowest, this provides the best lift over drag, or L/D max.

  4. 4) Vortex generators help delay airflow separation at slow airspeeds by...
    Mark Evans

    Vortex generators add energy to the boundary layer which helps reduce the stall speed of an aircraft.

  6. 6) What situation would produce the greatest left turning tendency due to P-Factor?
    Aleksander Markin

    The situation that would create the greatest amount of left turning tendencies from P-Factor would be slow airspeed, high angle of attack, and a high power setting.
