What is range factor in cruise method 1?(a) \(\left[\frac{V_{mdi}}{C}

1.	What is range factor in cruise method 1?(a) \(\left[\frac{V_{mdi}}{C} E_{max}\right]\)(b) \(\left[\frac{V_{max}}{C} E_{max}\right]\)(c) \(\Big\{\frac{2u^3}{u^4+1}\Big\}\)(d) \(\Big\{\frac{2u^4}{u^4+1}\Big\}\)I had been asked this question in unit test.This interesting question is from Cruise Method 1 topic in chapter Cruising Performance of Aircraft Performance
Answer» CORRECT choice is (a) \(\left[\frac{V_{mdi}}{C} E_{max}\right]\) To EXPLAIN I would say: Range factor in cruise method 1 is given by \(\left[\frac{V_{mdi}}{C} E_{max}\right]\). The range equation in cruise method 1 is given by R1 = \(\left[\frac{V_{mdi}}{C} E_{max}\right]\Big\{\frac{2u^3}{u^4+1}\Big\}\) ln ω where V is TRUE AIRSPEED, C is specific FUEL consumption, L is lift, D is drag, Emax is endurance and ω is fuel ratio.
