Airlines quickly realized the value of jet streams and started implementing them while planning routes. 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).Jet streams are so helpful in air travel. The jet stream sits in the mid to upper troposphere; this is about five to nine miles up at levels where planes fly. The strong winds of the jet stream can provide a boost of speed for aircraft traveling from west to east, cutting down travel time.Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.

Why do pilots pay attention to jet streams?
Flying with the jet stream can greatly reduce flight times, as well as fuel consumption. For planes traveling east to west, it’s also important to keep an eye on jet streams. Pilots will fly above or below a jet stream to save time and fuel.
Why flying from west to east is faster?
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. Airplanes fly into the jet stream at 30,000 feet and then travel with these winds. You can watch a Breakdown about the jet stream here.
Is it good to fly in a jet stream?
By flying in a jet stream, aircraft travelling from west to east get carried along by the tailwind, saving them time – and/or fuel. In fact most airline pilots are trained to reduce airspeed when the winds are so much to their advantage, to save fuel costs – not to fly in the shortest possible time.
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 is supersonic flight banned?
In the 1950s and ’60s, Americans filed some 40,000 claims against the Air Force, whose supersonic jets were making a ruckus over land. Then in 1973, the FAA banned overland supersonic commercial flights because of sonic booms—a prohibition that remains in effect today.

Do planes fly at full speed?
A typical commercial passenger jet flies at a speed of about 400 – 500 knots which is around 460 – 575 mph when cruising at about 36,000ft. This is about Mach 0.75 – 0.85 or in other words, about 75-85% of the speed of sound. Generally speaking, the higher the aircraft flies, the faster it can travel.

How much does the jet stream affect flight time?
Flying along jet streams cut the journey down from 18 hours to a mere 11.5 hours, flying just under 25,000 feet.
Where is the strongest turbulence in the jetstream found?
Maximum turbulence usually occurs near the mid-level of the storm, between 12,000 and 20,000 feet and is most severe in clouds of the greatest vertical development.
Does Jetstream cause turbulence?
The jet stream is driven by these temperature differences, and the strengthening trend at cruising altitudes is causing an increase in turbulence-driving wind shear, which had gone unnoticed until now.
Why Isn’t It Faster To Fly West?

Why don’t planes fly east from Australia to America?
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.
Is jet lag worse going east or west?
Most people find that jet lag is worse when traveling east than it is when traveling west13. 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.
Does the spin 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.
Do pilots avoid jet stream?
Conversely, planes flying in the opposite direction lose time and expend more fuel by flying into the headwind a jet stream produces, and pilots usually adjust their flying altitude to avoid them.
Why do planes not fly over Atlantic?
Early aircraft engines did not have the reliability needed for the crossing, nor the power to lift the required fuel. There are difficulties navigating over featureless expanses of water for thousands of miles, and the weather, especially in the North Atlantic, is unpredictable.
Why do planes fly north to Europe?
Planes travel along the shortest route in 3-dimensional space. This route is called a geodesic or great circle. While map projections distort these routes confusing passengers, the great circle path is the shortest path between two far locations. This is why pilots fly polar routes saving time and distance.
Why don’t they put parachutes on planes?
Short answer: There are a few reasons, including the lack of parachute training of passengers, high speed of the airplane, cold temperatures at that altitude, non-conducive design of commercial planes and the cost spike, which make putting parachutes onboard commercial airplanes unviable.
Where does toilet waste go on a plane?
The vacuum toilet used on planes, patented by James Kemper in 1975, sucks the waste into a holding tank where it is stored until the plane lands on the ground. Blue liquid, called Skykem, disinfects the bowl and helps kill odours. When you say planes “usually” wait until they have landed to empty the tank …
Why does it take longer to fly back from Hawaii?
The reason it took so much longer to fly back is the jet stream, a river of fast-moving air high up in the sky. Jet streams are usually about 100 miles wide. They can be thousands of miles long and are found all over the earth. To be called a jet stream, the wind must be moving faster than 60 mph.
Why do you not hear sonic booms anymore?
Why don’t we ever hear sonic booms any more? Noise abatement regulations halted supersonic flight (by civil aircraft) over U.S. land. The Concorde could still take off and land here because it broke the sound barrier over the ocean, but it’s no longer in service.
Why Do Airplanes Take Longer to Fly West than East?

Can civilian aircraft go supersonic?
A supersonic transport (SST) or a supersonic airliner is a civilian supersonic aircraft designed to transport passengers at speeds greater than the speed of sound. To date, the only SSTs to see regular service have been Concorde and the Tupolev Tu-144.
Can a passenger jet break the sound barrier?
Although Concorde and the Tu-144 were the first aircraft to carry commercial passengers at supersonic speeds, they were not the first or only commercial airliners to break the sound barrier.
