Default Caution, BLAST AREA

sorry but i have to correct that statement. all airplanes make wake turbulence. the only time it isn't noticeable is on take off or landing roll. it starts at the point of liftoff and stops at the touchdown point. however, it is at its strongest when the plane is heavy, clean,(no flaps or gear) and slow. the contrails you see coming off of full scale planes is in a sense wake turbulence. it comes from the two halves of the airflow going over the wings coming together. the pressure must equal to the normal outside pressure. Bernoulli's principal of lift is that the higher airflow speed over the top of the wing is at less pressure than that going around the bottom half. but they must equal when they are off of the trailing edge of the wing.
and yes, prop wash will get your models too!!!

sorry for the buzzkill, but just wanted to clear that up if anyone got confused.
Sorry to have to correct that statement, but you must not 3D.

When 3Ding, the wing is not generating any lift, thus Bernoulli has got his feet kicked up enjoying a cold frosty. If no high pressure under the wing, then no low above.

I am sure JohnVH 3D's.

Great pics Gator. By the way, you don't have to warn anybody of wake turbulence if a 727 is torkin' on the airway.
