  for and the takeoff distance properly com- 
  puted for 
  the existing conditions. Since 
  obstacle clearance distance is generally a 
  function of the same factors which affect 
  takeoff distance, the obstacle clearance dis- 
  tance is usually related as some proportion 
  of the takeoff distance. Of course, the take- 
  off and obstacle clearance distances related 
  by the handbook data will be obtained by 
  the techniques and procedures outlined in the 
  handbook. 
  TYPICAL ERRORS. The takeoff distance 
  of an airplane should be computed for each 
  takeoff. A most inexcusable error would be to 
  attempt takeoff from a runway of insufficient 
  If the airplane is subject to a sudden pull-up 
  or Jteep tzzra after becoming airborne, rhe,resulr 
  may be a stall, spin, or reduction in initial rate 
  of climb. The increased angle of attack may 
  exceed the critical angle of attack or the in- 
  crease in induced drag may be quite large. For 
  this reason, any clearing turns made immedi- 
  ately after takeoff or deck launch must be slight
