YES
No. The wingtip is the ONLY portion where energy (lift) is being lost.
In terms of induced lift/drag (and wake turbulence) the only important factor here is the wingtips and the airflow lost over them.

For some reason, the system won't let me "quote" the following:
"Wake turbulence and wingtip vortices are not one and the same, one is the produce of the other. Wingtip vortices are the main contributor to wake turbulence, but they are not the sole perpetrator. Simple aerodynamics, which point to turbulence being created by every part of the aircraft, lift being created by every part of the aircraft, and vortices being created by several points on the aircraft prove that conclusively. To say that wingtip vortices are the ONLY cause of wake turbulence is absolutely incorrect."

Ok, wait a minute here...are you saying that the ONLY portion of the wing where air passes from higher pressure to lower pressure is the wingtip?

If that were true, the only portion of the wing that would create lift would BE the wingtip.

The entire aircraft creates lift, but the wings create the majority. Air flows over every surface of the craft, and does NOT just escape the wings at the wing tips.

Not to sound condescending: But I gotta say that at this point that I'm done kicking a dead horse. I'm crying UNCLE! You need to do some research on basic aerodynamics because you keep confusing the differences between induced drag and parasite drag. Regardless, we've both drifted away from the basic topic of this forum which, if I remember correctly, had to do with wake turbulence and separation limitations of the Airbus 380.
By the way: Airbus SUCKS!
