1.	Determine wing loading for civil aircraft if lift-off speed is 80m/s and maximum lift coefficient is 2.8.(a) 9071.07(b) 9111(c) 911(d) 91The question was posed to me during an online exam.This is a very interesting question from Wing Loading topic in chapter Thrust-Weight Ratio and Wing Loading of Aircraft Design
Answer» CORRECT OPTION is (a) 9071.07 Best explanation: GIVEN, a civil aircraft. Lift off speed V1 = 80m/s, maximum lift coefficient CL=2.8. WING LOADING is given by, W/S = 0.5ρV^2CL Where, V = V1/1.1 = 80/1.1=72.72m/s Hence, wing loading is given by, W/S = 0.5ρV^2CL W/S = 0.51.22572.72^2*2.8 = 9071.07.
