  APPLICATION OF AERODYNAMICS 
  TO SPECIFIC PROBLEMS OF FLYING 
  
  in the case of powerplant failure or malfunc- 
  tion. When a powerplant failure or malfunc- 
  tion occurs, it is usually of interest to obtain a 
  gliding flight path which results in the mini- 
  mum glide angle. The minimum glide angle 
  will produce the greatest proportion of glide 
  distance to altitude 
  result in 
  maximum glide range or minimum expendi- 
  for a specific glide distance.

  In the study of climb performance, the forces 
  acting on the airplane in a steady climb (or 
  glide) produce the following relationship:
