Does the Earth's rotation affect flight time?


Does the Earth's rotation affect flight time? In the frame of reference of the airplane, everything is stationary. Similarly, the airplane is already moving along with the surface of the Earth before it takes off. The rotation of the Earth has no direct significant effect on flight times in either direction. That's to a first order approximation.


Why flights don t fly west to east?

Airlines quickly realized the value of jet streams and began implementing them while planning routes. Since the jet streams flow from west to east, they make one leg of the journey much faster (when flying with the stream) and one slower (against the stream).


Is it faster going to or from Europe?

It's faster to fly east (usually) A non-transatlantic example might be a flight between Amsterdam and Singapore. A flight east will take nearly 13 hours, while flying west towards Europe will take nearly 15 hours.


Why are planes faster going east?

Foremost among them? Clear-air turbulence. Jet streams are, at their most basic, high-altitude air currents caused by atmospheric heating and the inertia of the earth's rotation—and they're the reason why flights from west to east are faster than the same route traversed in the opposite direction.


Why flights from US to Europe are shorter?

In summary, jet streams are the reason why flights take shorter when flying from the west to the east. While they do help to shave off up to a few hours from long flights in some cases, they are not entirely without drawbacks.


Do pilots correct for Coriolis effect?

There can still be a small Coriolis deflection even with the motion of the atmosphere, and pilots would need to correct for that. But the prevailing winds (jet streams, etc.) have a much larger effect on headings and flight times.


Why does it take longer to fly back from Europe?

It is the rotation of the Earth that is causing the longer flight times, but not because it's moving towards or away from the flying aircraft. It is instead due to its influence on wind patterns – the so-called high-altitude jet streams.


Is jet lag worse going to Europe or coming back?

It is widely acknowledged that jet lag is worse when travelling east, but this has nothing to do with the direction of Earth's rotation. Like many creatures, humans have a circadian rhythm that follows a 24-hour period and is kept in sync by the eyes' response to natural light levels over the day.


Why don t we fly east to go from India to USA?

Because the Earth is a three-dimensional sphere and not merely a two-dimensional flat, East-West surface. Because of this spherical shape, often times the shortest distance is flying more north and south, up over the Northern latitudes and the North Pole, rather than flying east/west over the Pacific.


Why don t planes fly west to Australia?

The most common reason is that there are no airstrips or airports on many of the small islands, so if a plane had to make an emergency landing, it would be difficult to find a place to land. Additionally, the Pacific Ocean is vast and remote, so if a plane were to go down, it would be very difficult to find.


Why can t airlines just fly eastward from Russia for example to the usa?

There are several reasons why, but the big two are to do with the curvature of the earth and the jet streams. Guessing that it was a safety precaution wouldn't be entirely wrong either, as when planning a route many pilots prefer to maximize the number of airports along their flight path.
