Good luck!


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

    Wing tip vortices are associated with induced drag. In general, induced drag is greatest at slow speeds and high angles-of-attack.

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

    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. To combat the problem, designers often add wing washout.

  3. 3) The point where the parasite drag curve intersects the induced drag curve is _________.

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

  4. 4) Wing vortex generators help delay airflow separation at slow airspeeds by _______.

    Vortex generators add energy to the boundary layer, which helps delay airflow separation and reduces the stall speed of an aircraft.

  5. 5) As flaps are extended, the _____ moves _____.

    As you extend flaps, the center of pressure moves aft, causing a nose down pitching moment to occur in most aircraft.

  6. 6) Which scenario would produce the greatest left turning tendency due to P-Factor?

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

That was a tough one…

You scored %. Better luck next time!
