My ground kit has the following question & answer in it:
"When departing behind a heavy aircraft, the pilot [of the smaller aircraft] should avoid wake turbulence by maneuvering the aircraft...above and upwind from the heavy aircraft."
OK, the above part I understand, that is obvious since wake vortices sink behind the generating aircraft. But how could I possibly position myself UPWIND of a departing aircraft? He is going to take off INTO the wind, like I am, and therefore I will be taking off DOWNWIND from him, correct? If he and I stopped dead in our tracks in the sky, and he blew smoke out his window, it's going to blow DOWNwind to me.
Perhaps I am not understanding this question correctly?
This is an explanation to the answer I found online:
"The proper procedure for departing behind a large aircraft is to rotate prior to the large aircraft's rotation point, then fly above and upwind of the large aircraft. Since vortices sink and drift downwind this should keep you clear."
Again, how do I get upwind of the heavy aircraft, without overtaking it?
