11A). The/air speed over the top off a wing heeds to 'be faster than the air speed under the wing. This creates a pressure difference that lifts the airplane. Most airplanes need a pressure difference of about lOOON/mAZ to over come their weight. During takeoff, the plane's speed and; therefore, the airspeed under the wing is 60.0m/s. How fast is ' the air speed above the wing in order to lift the airplane? travel a greater distance . . Air above the wing must k
