  AIRPLANE PERFORMANCE 
  
  cause the airplane to descend. However, as 
  speed is reduced below the maximum level 
  flight speed, parasite drag reduces and allows 
  increased load factors and bank angles and 
  reduced radius of turn, i.e., decreased parasite 
  drag allows increased induced drag to accom- 
  modate turns within 
  thrust 
  available. Thus, the considerations of con- 
  stant altitude will 
  increase the minimum turn 
  radius above the aerodynamic limit and define 
  a particular airspeed for minimum turn radius. 
  factors (aero- 
  dynamic, structural, and power) may combine 
  to define the turning performance of an air- 
  Pl ane. Generally, aerodynamic and structural 
  limits predominate at low altitude while aero- 
  dynamic and power limits predominate at high 
  altitude. The knowledge of this turning per- 
  formance is particularly necessary for effective 
  operation of fighter and interceptor types of 
  airplanes.
