Wing-loading Vs Ride & Turbulence

Fri Mar 09, 2007 7:43 pm

Having a higher wing-loading has it's disadvantages (longer take-off roll, slower climb rate), but doesn't this provide a smoother ride and better ability to penetrate turbulence without over-stressing the airframe? I believe the B747-8 will have significantly higher wing-loading than the A380, so would a better ride and ability to handle turbulence favor the B747-8 in these measures of performance?

Overstressing the airframe is really not a particular consideration with high wing loading (IE: less square feet of wing area for the same weight) as the structure is built to accomodate, however that higher wing loading will generally provide a slightly smoother ride in turbulence.
It however is very subjective, and what appears to work with some aircraft does not, with others.

It has more to do with wing-mounted engine placement, and the wing bending relief provided, among others.
