Cruise method 1 is ideal for troposphere.

A. True

B. False

I got this question in my homework.

My question is taken from Cruise Method 1 topic in chapter Cruising Performance of Aircraft Performance

Correct option is B. False

The explanation: Cruise method 1 is ideal for stratosphere. The range equation in cruise method 1 is given by R1=\(\Big[\frac{V_{mdi}}{C}E_{max}\Big]\Big\{\frac{2u^3}{u^4+1}\Big\}\)lnω where V is true airspeed, C is specific fuel consumption, L is lift, D is drag, Emax is endurance, u is relative airspeed and ω is fuel ratio.
