I'm not sure how much of an effect 200m would make for air resistance. Dubai is right on the gulf, therefore right close to 0m above MSL (mean sea level), and Winnipeg is in the range of 230m so where I am right now is basically the same distance above sea level. Maybe a noticeable difference would exist in Denver or another city somewhere in the 1 mile above sea level range.
Heck you could get even more technical that since Dubai is around 25[sup]o[/sup]N latitude, they would experience a weaker pull of gravity than Winnipeg at 50[sup]o[/sup]N latitude due to the flattening of the Earth near the poles. :whistling:
