26 of40 Coefficient of Lift, or Airfoil Ratings Training
  Symmetrical airfoil produces less lift No, the symmetrical airfoil has a lower coefficient of lift than the asymmetrical airfoil. Since the top and bottom halves of the symmetrical airfoil are the same, you have to tilt the airfoil, which changes the way the air flows over it, to get lift. If the air over the top of the airfoil doesn't flow much faster than the air below it, then you don't get as much lift.
