No, it actually takes less time to fly against the Earth's rotation (east to west) compared to flying in the same direction as the Earth's rotation (west to east). This is because the Earth rotates from west to east, completing one rotation in approximately 24 hours. The rotational speed of the Earth's surface at the equator is about 1,670 kilometers per hour (1,040 miles per hour).
When an aircraft flies in the same direction as the Earth's rotation, it can benefit from the additional speed provided by the Earth's rotation. This is known as the "jet stream effect." The aircraft effectively rides along with the Earth's rotational speed, resulting in a faster ground speed and shorter travel time.
Conversely, when an aircraft flies against the Earth's rotation, it is flying in the opposite direction of the Earth's rotational speed. As a result, the aircraft's ground speed is reduced, and it takes slightly longer to reach its destination compared to flying with the Earth's rotation.
However, it's important to note that the effect of the Earth's rotation on flight times is relatively minor when considering commercial air travel. Factors such as wind patterns, air traffic control, flight planning, and aircraft performance have a more significant impact on flight durations than the Earth's rotation.
