  6. Levels of Turbulence Light Moderate Severe Extreme

  7. How turbulence info gets to controllers Pilot reports climbing, descending, at cruise altitude Weather briefings from other controllersor from supervisors Review of current and forecasted upper winds

  8. How controllers report turbulence PIREPs Relief briefings Calls to adjacent sectors or facilities

  9. Effects of turbulence in the NAS Changes in altitude crossing restrictions Route changes Cruise altitude changes Loss of speed control as a tool in getting and maintaining spacing between aircraft Holding in the hope of improving conditions Reportable incidents
