  flight path and angle of attack. Because of 
  the field of orientation available to the LSO,

  and stall speed in the turn. Figure 6.4 illus- 
  trates the typical change in thrust required 
  caused by a steep turn. A steep turn may cause 
  the airplane to stall or the large increase in in- 
  duced drag may create an excessive rate of 
  descent. In either case, there may not be suf- 
  ficient altitude to effect recovery. 
  If the .air- 
  plane is not properly lined up on the final ap- 
  proach, it 
  is certainly preferable to take a 
  waveoff and go around rather than “press on 
  regardless” and attempt to salvage a decent 
  landing from a poor approach. 
  
  The specific techniques necessary during the 
  phase of approach and landing may vary con- 
  siderably between various types of airplanes 
  and various operations. However, regardless 
  of the airplane type or operation, there are 
  certain fundamental principles which will de- 
  fine the basic techniques of flying during ap- 
  proach and landing. The specific procedures 
  recommended for each airplane type must be 
  followed exactly to insure a consistent, safe 
  landing technique.
