The A380 and wake turbulence

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!

Not to sound condescending, but you do...and sorry, but you are the one who needs to do the research on basic aerodynamics. Beating a dead horse is right, especially with someone who has an incorrect idea of what produces lift, what destroys lift, what drag and vortices are and where they are created...you simply ignore facts, so I think I am done with you as well. You have one thing in your head that someone told you one fine day, that�s your story and you are sticking to it. If we all did that we would still be calling wake turbulence "prop wash" and "jet wash" as it was when I was getting my masters...it wasn't true then, but we thought it was because that is what they told us, and it�s what the text books and thesis all said. As active duty aircrew, we keep up new information, and guess what...it wasn't true then, and it isn't true now...


I'm done with the thread...tired of trying to say the same thing different ways to make someone understand...

Hey Freedom,
You claim to be a AF trained pilot, can you tell us what you flew and when you flew it? Perhaps the differences in you and AR is a result of the aircraft that you are familiar with?

I fly KC-135's in the Air National Guard. I also flew B-757/767's for a major airline until being furloughed earlier this year. In addition, I taught under-graduate level Aerodynamics & Aircraft Performance at Embry-Riddle.

Aerodynamic Theory doesn't change from one airplane to another. The priciples of lift, weight, thrust, and drag are the same across the board. I've only used standard terminology throughout these threads. From an aerodynamic standpoint, wake turbulence only applies to air being lost over the wingtips.

I do, however, have an open mind and am always willing to learn. If anyone can show me any publication on aerodyamics that counters my position/opinions that I've expressed here on this board, please post it/them here.

The whole aerodynamics discussion has been quite informative, but does anybody know if the A380 will require an increased separation compared to a 747?
