The main reason for the difference in travel time is due to the jet stream. The jet stream is high altitude wind that blows from the west to the east across the globe. … Next time you fly, pay attention to the duration of the flight and you will notice a shorter time for an eastbound flight versus a westbound flight.
Why is my flight time different?
The reason for the different flight times is simply the wind. … However, the Coriolis effect, caused by the rotation of the earth, causes winds to move right, in the direction of motion, in the northern hemisphere and left in the southern, making the wind blow east.
Why is the flight back from New York Shorter?
NASA That major jet stream over the northern hemisphere flows west to east, providing a lift for east bound flights and increased resistance for west-bound flights. … And this is why that flight from LA to New York is shorter than vice versa; it benefits from a jet stream-assisted tailwind at its back.
Why are west to east flights faster?
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). … Even on shorter transcontinental flights between cities New York and Los Angeles, jet streams can impact the flight time by nearly an hour.
Are flights shorter 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 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.
How often do flights change times?
The airline will either put you on another flight or they will return your money so that you can buy a different ticket. Airlines can, and do, change their timetables as often as they like… but most timetable changes occur on two specific week-ends every year, one in April and one in October.
Why do planes not fly over the Pacific?
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. As a result, straight routes don’t offer the shortest distance between two locations.
Why do you not feel the speed of an airplane?
Short answer: Because we’re moving at the same velocity as the Earth, in the same way that passengers inside an airplane don’t feel movement because they’re moving with the same velocity as the plane. People on a smooth flight don’t feel the plane’s movement.
Do planes fly faster than the Earth spins?
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 don’t planes fly over the North and South Pole?
The polar regions have special navigation concerns in the form of the magnetic fields which permeate them. These can make it difficult for planes to navigate because the polar areas interfere with magnetic navigational tools.
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.
Does the rotation of the Earth affect flight times?
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.
What causes jet streams?
Jet streams form when warm air masses meet cold air masses in the atmosphere. The Sun doesn’t heat the whole Earth evenly. That’s why areas near the equator are hot and areas near the poles are cold. … A jet stream is a type of air current that forms high in the atmosphere.
Which is faster flying east or west?
So actually, the Earth’s rotation really makes flying from east to west slower. … The real reason flights from west to east are quicker is down to jet streams. Jet streams are air pockets high up in the Earth’s atmosphere which move in a wavy pattern from west to east.
