A light aircraft has a weight of 10kN. The weight of the pilot and passengers is 5kN. The wing, a NACA 23012 aerofoil, has a chord length of 1.8m and wingspan of 25.6m. There are no flaps. (a) Reflect on the statement “the take-off speed at a 5 degrees angle of attack at sea-level” for this aircraft? (b) Evaluate the take-off speed for this aircraft at a 5 degrees angle of attack at sea level. [Take the density of standard air at sea level as r = 1.225 kg/m3.]
