Question

The endurance of cruise method 2 is identical to that of cruise method 1.

(a) True

(b) False

This question was addressed to me in final exam.

Enquiry is from Cruise Method 2 topic in portion Cruising Performance of Aircraft Performance

Answer 1

Correct answer is (a) True

For explanation I would say: The endurance of cruise method 2 is identical to that of cruise method 1. E=\(\Big[\frac{E_{max}}{C}\Big]\Big\{\frac{2u^2}{u^4+1}\Big\}l_n\omega\) 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.
