Answer»

Correct answer is (a) True

Easiest explanation: Step climb helps in saving fuel.Cruise method 1 is ideal for stratosphere and uses step climb which helps in saving fuel and is ECONOMICALLY efficient. 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.
