  The LSO, mirror landing system, and various 
  approach lighting systems will aid the pilot 
  in achieving the desired approach flight path. 
  THE LANDING FLARE AND TOUCH- 
  DOWN. The specific techniques of landing 
  flare and touchdown will vary considerably 
  between various types of airplanes. 
  In fact, 
  for certain types of airplanes, a flare from a 
  properly executed approach may not be de- 
  sirable because of the possibility of certain 
  critical dynamic landing loads or because of 
  the necessity for a certain standard of tech- 
  nique when aerodynamic flare characteristics 
  are critical. The landing speed should be the 
  lowest practical speed above the stall or mini- 
  mum control speed to reduce landing distances 
  and arresting loads. Generally, the landing 
  speed will be from 5 to 25 percent above the 
  stall speed depending on the airplane type 
  and the particular operation.
