An aircraft is flying with wing loading of 50 and maximum CL as 2.4. If density is 1.225 then, find the stall speed of the aircraft.(a) 5.832m/s(b) 5.823(c) 5.632m/s(d) 5.632I got this question by my school principal while I was bunking the class.This intriguing question originated from Wing Loading topic in portion Thrust-Weight Ratio and Wing Loading of Aircraft Design

Answer»

Right answer is (a) 5.832m/s

The BEST explanation: GIVEN WING loading W/S = 50, maximum CL = 2.4, density ρ = 1.225

Now, stall speed of aircraft is given by,

Vstall = \(\sqrt{2*(\frac{W}{S})(\rho*CL)} = \sqrt{2*(50)/(1.225*2.4)} = \sqrt{34.01}\) = 5.832m/s.
