text: The effect of proper takeoff t&city is important 
  when runway lengths and takeoff distances are 
  critical. The takeoff speeds specified in the 
  flight handbook are generally the minimum 
  safe speeds at which the airplane can become 
  airborne. Any attempt to take 05 below the 
  recommended speed may mean that 
  the air- 
  craft may stall, be difficult to control, or have 
  very low initial rate of climb. 
  In some cases, 
  an excessive angle of attack may not allow 
  the airplane to climb out of ground effect. On 
  the other hand, an excessive airspeed at takeoff 
  rare of climb and 
  may improve the initial 
  
  the  true airspeed (TAS) will
