[Physics] Rotation of earth and helicopter

coriolis-effect

If in a helicopter, you have an altitude and you maintain that altitude without any motion will you revolve around earth in 24 hours due to coriolis effect as helicopter unlike airplanes is not affected by wind speeds when it is stationary in air?

Best Answer

No, because you forgot to take into account the W-->E motion the helicopter had upon takeoff. What matters (ignoring winds and such) is the relative linear speed and the altitude. Calculate the circumference at the ground, compare with the circumference at altitude, and you'll see that since both the Earth and the helo have the same linear W-->E speed that you'll basically travel the difference in the two circumferences.
