An aircraft has a total wing area of 360 m². The air speed over its wings at take-off is 94 m/s and the air speed under its wings is 77 m/s. Assuming that air has a density of 1.29 kg/m³ and that the height difference between the upper and lower wing surface is negligible, what is the lift force generated (to two significant figures)? 680,000 N Q 750,000 N 68,000 N 450,000 N None of the other answers
