A fully loaded boeing aircraft has a mass of $$5.4 \times 10^5$$ kg. Its total wing area is $$500$$ m$$^2$$. It is in level flight with a speed of $$1080$$ km h$$^{-1}$$. If the density of air $$\rho$$ is $$1.2$$ kg m$$^{-3}$$, the fractional increase in the speed of the air on the upper surface of the wing relative to the lower surface in percentage will be ($$g = 10$$ m s$$^{-2}$$)
