  EFFECT OF SPEED. The general effect of 
  speed on induced drag is unusual since low air- 
  speeds are’associated with high lift coefficients 
  and high lift coefficients create high induced 
  drag coefficients. The immediate implication 
  is that induced drag inmaw with decreasing air 
  J@. 
  If all other factors are held constant to 
  single out the effect of airspeed, a rearrange- 
  ment of the previous equations would predict 
  “induced drag varies inversely as ,the 
  that 
  square of the airspeed.” 
  
  (and q (or EAS), S, AR are constant) 
  This expression defines the effect of gross 
  weight, maneuvers, and steep turns on the 
  induced drag, e.g., 10 percent higher gross 
  weight increases induced drag 21 percent, 4G 
  maneuvers cause 16 times as much induced 
  drag, a turn with 4s0 bank requires a load 
  factor of 1.41 and this doubles the induced 
  drag.
