A typical jet airliner has cruise thrust to weight ratio of 0.5. Determine at which aerodynamic efficiency this airliner is flying.

A typical jet airliner has cruise thrust to weight ratio of 0.5. Determine at which aerodynamic efficiency this airliner is flying. Correct Answer 2

Given, Thrust loading at cruise T/W Thrust loading at cruise T/W = 1 / (L/D) Hence, Aerodynamic efficiency (L/D) at cruise is, L/D = 1 / (T/W) = 1/0.5 = 2.
