text: An example of an acceleration profile is 
  shown by the second illustration of figure 6.12, 
  where the variation of velocity and distance is 
  defined for the case of uniformly accelerated 
  motion, i.e., constant acceleration. While the 
  case of uniformly accelerated motion doesnot 
  correspond exactly to the takeoff performance 
  of all airplanes, it is sufficiently applicable to 
  illustrate the principle of line speeds and ac- 
  celeration checks. 
  If the takeoff acceleration 
  of the airplane were constant, the airplane 
  would develop specific percentages of the take- 
  off speed at specific percentages of the takeoff 
  distance. Representative values from 
  figure 
  6.12 are as follows:
