Which of the following is the correct integrated range equation of cruise method 3?(a) R=\(\frac{1}{C}\Big(\frac{2W_i}{S\rho}\Big)^{\frac{1}{2}}\frac{C_L}{C_D}2\Big(1-\omega^{\frac{-1}{2}}\Big)\)(b) R=\(\frac{V}{C}\int_{W_i}^{W_f}\frac{dW}{D}\)(c) R=\(\Big[\frac{V_{mdi}}{C}E_{max}\Big]2u_i\Big\{tan^{-1}\Big[\frac{1}{u_{i}^2}\Big]-tan^{-1}\Big[\frac{1}{\omega u_{i}^2}\Big]\Big\}\)(d) R=\(\frac{1}{C}\Big(\frac{2W_i}{S\rho}\Big)^{\frac{1}{2}}\frac{C_{L}^{0.5}}{C_D}2\Big(1-\omega^{\frac{-1}{2}}\Big)\)I have been asked this question in semester exam.My doubt is from Cruise Method 3 topic in division Cruising Performance of Aircraft Performance |

Answer» Correct choice is (c) R=\(\Big[\frac{V_{mdi}}{C}E_{MAX}\Big]2u_i\Big\{tan^{-1}\Big[\frac{1}{u_{i}^2}\Big]-tan^{-1}\Big[\frac{1}{\omega u_{i}^2}\Big]\Big\}\) |
