  pilot 
  interprets that his airplane is below 
  the desired glide path, his first reaction rnu~t 
  trot be to just ease the nose up. An increase 
  in angle of attack without an increase in 
  power will 
  lower the airspeed and greatly 
  increase the induced drag. Such a reaction 
  could create a high rate of descent and lead 
  to very undesirable consequences. The an- 
  gle of attack indicator coupled with 
  the 
  mirror landing system provides reference to 
  the pilot and emphasizes that during the 
  steady approach “angle of attack is the 
  primary control of airspeed and power is the 
  primary control of rate of climb or descent.” 
  Steep turns during approach at low airspeed 
  are always undesirable in any type of air- 
  plane because of the increased stall speed and 
  induced drag. Steep turns at low airspeeds 
  in a low aspect ratio airplane can create 
  extremely high induced drag and can incur 
  dangerous sink rates. 
  
  Some of the most important ramifications of 
  
  the modern high speed configuration are: 
  
  (1) During takeoff where the airplane must 
  not be over-rotated to an excessive angle of 
  attack. Any given airplane will have some 
  fixed angle of attack (and CJ which produces 
  the best takeoff performance and this angle 
  of attack will not vary with weight, density 
  altitude, or temperature. An excessive angle 
  of attack produces additional 
  induced drag 
  and may have an undesirable effect on takeoff 
  performance. Takeoff acceleration may be 
  seriously reduced and a large increase in
