  The additional speed pro- 
  vides a more favorable margin of flare capabil-

  (low aspect ratio, 
  low glide 
  ratio). 
  The

  technique must emphasize 
  proper control of angle of attack and rate of 
  descent to prevent high sink rates and hard 
  landings. As before, to be sure that it will 
  not go unsaid, excessive airspeed at landing 
  creates its own problems-excessive wear and 
  tear on tires and brakes, excessive landing 
  distance, etc.

  The effect of the low aspect ratio planform 
  of modern airplanes emphasizes the need for 
  proper flying 
  low airspeeds. 
  techniques at 
  Excessive angles of attack create enormous 
  induced drag which can hinder takeoff per- 
  formance and incur high sink rates at landing. 
  Since such aircraft have intrinsic high mini- 
  mum flying speeds, an excessively low angle of 
  attack at takeoff or landing creates its own 
  problems. These facts underscore the 
  im- 
  portance of a “thread-the-needle,” professional 
  flying technique.
