Wake Turbulence Question

Thank you.. roger on the slow and high weight.. which equals high AOA which
create stronger vortices... fist time I've heard about gear and flaps
breaking up vortices..

as I said MY original response.. I'd have to go back and find the article I
read it from

also.. wake turbulence is the worst if the heavier aircraft (bizjet) is
configured for landing, flaps and gear etc.. if he was still gear up..
and
in level flight... the bumps would not be so bad even if you had 500ft.

A quote from a popular primary text:
"The greatest vortex strength occurs under CLEAN configuration, high
weight,
and slow speed." (emphasis mine)

(... and high air density) Their contention appears to be that flaps and
gear help break up the vortex pattern. The clean configuration at slow
speeds results in the highest AOA, supposedly the primary culprit.

Since the post, I did a little googling, and found the FAA AIM has basically
the same quote:

http://www.faa.gov/ATpubs/AIM/Chap7/aim0703.html

7-3-3. Vortex Strength

a. ...snip... The greatest vortex strength occurs when the generating
aircraft is HEAVY, CLEAN, and SLOW.

(this time the emphasis is theirs)
