Do Planes Travel Faster Going East West?

by | Last updated on January 24, 2024

, , , ,


Since the jet streams flow from the west to east, they make one leg of the journey much faster (when flying with the stream) and one slower (against the stream)

. Returning to the example from New York to London, we see flights may take even a slightly longer route to benefit from the jet stream.

Why is it quicker to fly west to east?


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.

Is it faster to fly with the rotation of the earth?

First, as the Earth itself rotates, it takes the air with it (thanks, gravity!). That includes the air through which planes fly. At the equator, the Earth spins about twice as fast as a commercial jet can fly. That rate slows the closer you get to the poles, but regardless,

it’s always going to be faster than a plane

.

Why do planes only fly east?

When they fly from the east to the west,

they try to plan their flight so the jet stream isn’t blowing against their airplane and giving them a bad headwind

. When they plan their flight from the west to the east, they look for the jet stream and try to fly so it can give them a big tailwind and help them fly faster.

Why do planes not fly over the Pacific?

Flying over the Pacific Ocean is avoided by most airlines for most flights because

it usually doesn’t make sense to fly over it when shorter and safer routes exist

. The Pacific Ocean is also more remote and less safe than the Indian and Atlantic Oceans to fly over, resulting in a higher chance of a plane crashing.

Why don’t planes fly in a straight line?

Instead of relying on flat maps,

airplanes follow “great circle” routes that account for the curvature of the Earth

. What looks like a long detour on a flat map actually turns out to be the shortest route across the globe through the air.

Why don’t we fly west to Japan?

The primary reason airplanes don’t fly over the Pacific Ocean is because

curved routes are shorter than straight routes

. Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather, it’s spherical.

Is it better to fly east or west?

The verdict:

Traveling several time zones to the east causes worse jet lag than flying the same number of time zones west

, and although the precise mechanism isn’t known, it probably reflects the greater difficulty of advancing rather than delaying the body’s internal clock.

Is jet lag worse east or west?


Most people find that jet lag is worse when traveling east than it is when traveling west


13

. Jet lag differs based on the direction of travel because it’s generally easier to delay your internal clock than advance it. Jet lag does not occur on north-south flights that do not cross multiple time zones.

Why can’t planes go faster?

Airplanes don’t fly faster because

it is not in their economic best interest

. Flying faster means burning more fuel. This means ticket prices would go up. History has shown passengers rather spend more time in the air if it means lower airfares.

Why do planes not fly over Atlantic?

The reason for this is that

the earth revolves on its axis, forcing the middle to bulge out slightly

. The curvature of the earth and its extra equatorial width mean that curving towards the poles is a shorter distance than flying in a straight line.

Is it faster to fly north or south?


When an airplane is moving in the same direction as the wind, it will travel faster

because it is getting that welcome boost of tailwind. When an airplane is travelling opposite the wind direction, however, it will get that drag resulting in a slower travelling speed.

Why do planes not fly west?

The short answer is no, because

our plane is also affected by Earth’s spin

, which means we’re spinning away from our destination while our destination is spinning towards us.

Can a helicopter fly across the Atlantic?


A helicopter can fly across the Atlantic

– and this has been achieved several times. The first transatlantic helicopter flight took place in 1952. The first non-stop transatlantic helicopter flight took place in 1967.

Why is it forbidden to fly over the Taj Mahal?

The Taj Mahal

Although there’s no official no-fly zone over the ivory mausoleum, there is a mile-and-a-half radius above the historic site which security agencies consider to be a no-go when it comes to flying. This is because of

security reasons – as well as risks to the building’s white marble from plane pollution

.

Do passengers know when a plane is crashing?


Passengers Sometimes Receive No Warning That The Plane Is Crashing

. Two factors can determine whether or not passengers are informed of an impending plane crash: if the pilot is in control of the crash, and what is causing the crash.

Can a plane fly over Mount Everest?


The first men to fly over Mount Everest did so in an unpressurized biplane

. The two planes fly towards Lhotse and Everest at 32,000 feet. Though the 29,029-foot-high summit of Mount Everest was first conquered on foot by Tenzing Norgay and Edmund Hillary in 1953, it was conquered by air two decades earlier.

Why do planes not fly over Tibet?

The leading reason for aircraft avoiding the region is the

high average height of the terrain

. This is over 14,000 feet. Aircraft, of course, cruise much higher than this. But the procedure in the event of an emergency such as cabin depressurization is to descend to 10,000 feet before diverting to an airport.

Why do aircraft fly at 35000 feet?

The biggest reason for this altitude lies in

fuel efficiency

. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak. Spending less on fuel is also great for airlines, for obvious reasons.

Can planes fly upside down?

But wings on aerobatic planes are curved on both the upper and lower sides. With this symmetric design,

the plane can fly either normally or inverted

. The pilot can flip from one to the other by altering the angle of attack.

Can you fly directly from Russia to Alaska?

Is it possible to cross from Alaska to Russia legally?

Yes, but not via the Bering Strait

. It is possible to depart from Alaska outside of a port of call (a community that has customs and immigration processing facilities), but you must arrive in an official port in Russia.

What is the longest flight in the world?

What is the longest flight in the world by distance? The longest flight in the world by distance is QR921.

Qatar Airlines’ Auckland to Doha route

comes in at 14,535 km/9,032 mi/7,848 nm.

Why is jet lag worse east to west?

A study published in 2016 crunched the numbers on why travelling east is worse for jet lag. In short,

your body’s natural rhythm follows a 24.5-hour day, slightly longer than the standard 24-hour sun-up, sun-down rhythm

. That means that if you’re travelling east over many timezones, you’ll ‘lose’ additional time.

What happens to time when you travel east?

The prime meridian is also where the system of 24-hour timekeeping that is called Greenwich Mean Time (GMT) originated. As you go east from the prime meridian,

the time zones increase consecutively by one hour

, or conversely, decrease consecutively by one hour as you go west.
