I guess Mxmanic uses the FAA AIM as his main source in his "research".
Section 7.3.1 is about wake turbulence. A couple of interesting quotes from
that section, that Mx has not seen fit to share with us:

Heh. Many of his responders seem to have done even less "research".
Instead they substitute insults for information, hoping they'll look
smarter than him. They don't seem to realize that it just makes them
look dumber.

c) "The greatest vortex strength occurs when the generating aircraft is
HEAVY, CLEAN, and SLOW."

In contrast, a light aircraft doing a 360 is usually LIGHT, CLEAN and
(relatively speaking) FAST. Very different conditions, especially regarding
two major sources of wake: the AoA of the wing (which affects the tip
vortices) and the power setting (which affects the propwash strength).

Of course, LIGHT does not mean "light aircraft". Some 152s are
vortex HEAVY in the case of big instructors and students ;-)

For vortex strength, the term HEAVY is used in a relative manner. A
small plane that is lightly loaded will create less vortex strength
than the same small plane that is heavily loaded, because the actual
AOA is larger in the latter case.

The actual AOA is the key for (HEAVY) more load, (CLEAN) less flaps
and (SLOW) less speed. It's greater in all those cases.

Auugh. Four year old calling me. Later..
