Question

Step climb helps in saving fuel.

(a) True

(b) False

I had been asked this question during an online interview.

Question is taken from Cruise Method 1 in chapter Cruising Performance of Aircraft Performance

Answer 1

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.
