# Coriolis Effect vs airplane

So, if I build a highway from north pole towards equator and sit in a car, speed pretty fast towards it, I should feel force with the Earths rotation due to the different rotation speeds of this points. Which is basically 0 at north pole and 1000 mph on equator, so I should gradually pick up 1000mph of speed on my journey.

Why doesn't this happend with objects that are above the ground, for example, airplanes that fly throught atmosphere. The atmosphere itself is rotating with the Earth, therefore there should be the same difference in speed. Shouldn't airplanes and other objects gradually pickup speed because of the speed difference in atmosphere itself?

• Why do you think they don't pick up speed? At the equator, you are doing 40,000 km/24 hours. Whether you are in the air, or on the ground. Because the plane moves relative to the air - and the air moves with the earth. If there was no atmosphere (e.g. for a satellite) a circumpolar orbit does indeed appear (from Earth's perspective) to change speed. Of course the satellite itself doesn't know and doesn't care...

• At the poles when the Coriolis effect is at its strongest, a 600 mph airplane would be accelerating at just under 0.02 m/s, which is about a 500th of gravity. It's something you could notice if you looked closely, but it's not anything you have to worry about. It's no different than flying the plane slightly tilted so it accelerates just a bit to one side.

• Doug Morris - Captain Air Canada says in short The Earth’s rotation does not affect travel time.
