An aircraft has to be designed to operate at aerodynamic efficiency of 10 at cruise. Find the required thrust to weight ratio for maintaining this unaccelerated steady level flight. Correct Answer 0.1

Given, aerodynamic efficiency L/D = 10. Now, for given conditions, thrust to weight ratio T/W is given by, T/W = D/L = 1/10=0.1.
