text: Approach path C of figure 6.4 typifies the 
  long, shallow approach with 
  too small an 
  inclination of the flight path.. Such a flight 
  path requires a relatively high power setting 
  and a deficiency of airspeed is a usual conse- 
  quence. This extreme of an approach path 
  is not desirable because it is difficult to control 
  the point of touchdown and the low speed 
  may allow the airplane to settle prematurely 
  short of the intended landing touchdown. 
  
  In preparation for the landing, several factors 
  must be accounted for because of their effect 
  on landing distance, landing loads, and arrest- 
  ing loads. These factors are: 
  
  Some approach path between the extremes 
  of A and C must be selected, e.g., flight path 
  B. The desirable approach path must not 
  incur excessive speed and rate of descent or 
  require excessive flaring prior to touchdown. 
  Also, some moderate power setting must be 
  required which will allow accurate control 
  of the flight path and provide suitable waveoff 
  characteristics. The approach flight path 
  cannot be too shallow 
  for excessive power 
  setting may be required and it may be difficult  (1) Landing gross weight must be con- 
  sidered because of its effect on landing speed 
  and landing 
  is 
  accomplished at a specific angle of attack or 
  margin above the stall speed, gross weight 
  will define the landing speed. In addition, 
  the gross weight is an important factor in 
  determining the landing distance and energy
