http://www.cnn.com/2005/TECH/03/31/emirate...r.ap/index.htmlI have to wonder, with buildings getting taller and taller, what effect this would have on aircraft flying on the leeward side of such buildings?-John

I don't believe it will have much effect unless they fly very close (i.e. closer than they should fly). Helicopters fly around skyscrapers today without too much trouble.

I was wondering due to the height--a good thousand feet over most of the top ten skyscrapers, whether the upper stories might penetrate stronger winds aloft and cause unforseen issues. It begs the larger question, at what height to winds significantly change from ground level in speed and direction. Probably a question with many answers.-John

Several UK airport AIPs warn of turbulence from buildings. At Gatwick (EGKK):"Pilots are warned, when landing on Runway26L/R in strong southerly/south-westerly winds, of the possibility of building induced turbulence and windshear effects."

Yes, I believe you're right. Let's hope they don't build it too close to an airport. :)
