  Since the, induced drag predominates at low 
  speeds, steep turns at low speeds can produce 
  significant increases in thrust or power required 
  to maintain altitude. Thus, steep turns must 
  be avoided after takeoff, during approach, and 
  especially during a critical power situation 
  from failure or malfunction of a powerplant. 
  The greatly increased induced drag is just as  it is apparent that the

  steady, coordinated turn requires specific values

  For example, a bank angle of 60’
