Question:

An Airbus A 380-800 passenger air plane is cruising at constant altitude on a straight line with a constant speed. The total surface area of the two wings is 395 m². The average speed of the air just below the wings is 267 m/s, and it is 293 m/s just above the surface of the wings. What is the mass of the airplane? The average density of the air around the airplane is ρ_air = 1.07 kg/m³.
