A light airplane uses a NACA 4415 airfoil. It has a rectangular wing planform, with an area of 15.3 m2 and a span of 10.2 m. The aircraft is flying at a gross weight of 7340 N. Neglecting any finite wing effects (induced drag) and assuming sea level conditions, at what angle of attack will the aircraft be flying when its airspeed is 160 km/h?
