Afrequently quoted rule of thumb in aircraft design is that wings should produce about 1000 n of lift per square meter of wing. (the fact that a wing has a top and bottom surface does not double its area.) part (a) at takeoff, an aircraft travels at 69 m/s, so that the air speed relative to the bottom of the wing is 69 m/s. given the sea level density of air to be 1.29 kg/m3, how fast must it move over the upper surface to create the ideal lift?
