Aerodrome Light Signals. HELP?
Not to confuse a student, but I'd have thought a heavy/dirty configuration would produce more wake turbulence. Wake turbulence is caused by the differential in the air pressure between the top and bottom of the wings. As these meet -at the wing tips, and the edges of the flaps- they cause vertices or violently spinning air. Think a mini horizontal tornado.
A heavy aircraft with flaps and gear out is flying at a higher AOA, therefore higher pressure difference.
