  duction in the slope of the lift curve and maxi- 
  mum lift coeflicient. When the sweepback is 
  large and combined with low aspect ratio the 
  lift curve is very shallow and maximum lift 
  coefficient can occur at tremendous angles.of 
  attack. The lift curve of one typical 
  low 
  aspect ratio, highly 
  tapered, swept wing air- 
  plane depicts a maximum lift coefficient at 
  approximately 43’ angle of attack. Such dras- 
  tic angles of attack are impractical in many 
  respects. If the airplane is operated at such 
  high angles of attack an extreme landing gear 
  configuration is required, induced drag is ex- 
  tremely high, and the stability of the airplane 
  may seriously deteriorate. Thus, the modern 
  conhguration of airplane may have “minimum  .(E) The pointed tip wing of taper ratio

  purposes, the pointed tip will be stalled at any
