Can someone explain wing loading?
Thanks Kevin.
Other than the stall info, wing loading is pretty much the same as blade loading in helicopters. I guess that is why the Blackhawk is so stable in the rear. The tailrotor produces something like 10% of the total lifting force for a given gross weight. That is a lot of lift for those little paddles back there. But they are spinning quiet fast.

What is the significant of this? Does it lessin the amount of turbulence you feel compared to an airplane of equal size/weight with low wing loading? Thanks, Fred Imagine that you have two aircraft that weigh the same, one with a high wing loading, and one with a low wing loading, flying the same speed through the same up-drafts and down-drafts. The angle of attack changes instantly as the aircraft penetrates into the up-drafts and down-drafts. Both aircraft are going the same speed, so the amount that the angle of attack changes is the same. But, the aircraft that has a lower wing loading will experience more g in the bumps, because the bigger wing will have a larger change in the amount of lift developed due to that change in angle of attack. So, if everything else is the same, the aircraft with the higher wing loading will have a smoother ride in turbulence. Now, if everything else is the same, it will also have a higher stall speed, use up more runway during take-off and landing, and be more likely to kill you if you have to do a forced landing.
