  If engine failure occurs below refusal

  If engine failure occurs above refusal speed

  an accident is inevitable. Within 
  of speeds, the airplane cannot effect a safe 
  takeoff at L’s with one engine inoperative or 
  a safe stop on the remaining runway. For this

  speed is generally referred to as the 
  speed and it is a function of the same factors 
  which determine the takeoff performance, e.g., 
  density altitude, gross weight, 
  temperature, 
  humidity, etc.
