And the Airbus that crashed out of LGA Years ago was Flea Hit when it took off shortly after another did.
Not arguing with your point, as one who once flew a Bonanza through the wake of a Lockheed Electra, but is my memory fooling me when I think I recall that the person driving the Airbus exceeded the structural design of the rudder when trying to correct?
That airbus crash was determined to be due to overly aggressive rudder response to the WT, not due to the WT itself. There was 5 minutes separation, which I believe is typical today.
Any aircraft needs to be mindful of WT, whether it considers it a flea or a monster. For example, while waiting to take off, watch the life off point of the current take off... and be sure to lift off prior to that one. Especially if you are small and it is big.
I’d still maintain that any WT more than a few thousand feet away in altitude is nothing to worry about... a mere bump.
