Question

Wing loading is ratio of ___________

(a) weight of the aircraft and the reference area of wing

(b) reference area of wing and power of engine

(c) lift to drag

(d) aerodynamic force thrust to drag

This question was addressed to me in final exam.

I would like to ask this question from Wing Loading topic in section Thrust-Weight Ratio and Wing Loading of Aircraft Design

Answer 1

Right answer is (a) weight of the aircraft and the reference area of wing

To explain I would say: Wing loading is defined as the ratio of the weight of an aircraft to the reference area of wing. Similar to thrust loading, wing loading has major effects on the aircraft performance. Lift to drag ratio is defined as aerodynamic efficiency.
