text: The Supercritical airfoils do shift behind the point when a higher airspeed would change the airflow from laminar to turbulent, thus increasing the speed range where the wing has a good efficiency, and also decreasing power and fuel needs of the airplane.--Jgrosay (talk) 21:12, 9 August 2012 (UTC)
