various ways.</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">There is drag due to lift because the lift vector (
force ) is not perpendicular to the flight direction. Drag is a function of
lift and that component of the lift vector in the flight direction is called
induced drag.</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">Up, and down, both ailerons produce drag, but in
unequal amounts if the wing is in lift mode. The difference in drag for pattern
airplanes is small because of low wingloading ( low AOA ).</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">The symmetrical airfoil plays a role in keeping the
drag differential low because, to generate equal lift , upright to inverted,
requires a different AOA for the non-symmetrical section.</font></div>

forget? Nat</font></div></div>
