A jet aircraft has maximum lift to drag as 12. Find the value of the thrust loading at the cruise.

A jet aircraft has maximum lift to drag as 12. Find the value of the thrust loading at the cruise. Correct Answer 0.096

Given, maximum lift to drag = 12. Thrust loading at cruise T/W = 1 / (L/D at cruise) For, jet aircraft cruise lift to drag = 86.6% of maximum lift to drag = 86.6% of 12 = 0.866*12 = 10.392 Now, thrust loading at cruise, Thrust loading at cruise T/W = 1 / (L/D at cruise) = 1/10.392 = 0.096.
