Can planes fly in jet stream?

The high-altitude winds exist in both the northern and southern hemispheres and consist of a subtropical jet stream as well as a polar jet stream, where wind speeds can top out at 275 miles per hour. In the early 20th Century, the jet stream would change the game for planes flying from west to east.

Do planes fly faster in the jet stream?

Jet stream The reason for quicker flights while flying eastwards are jet streams. Put simply, they are fast-flowing, narrow air currents in the atmosphere found at high altitudes. Most airlines on transatlantic and transpacific routes use the polar stream while planning flight paths.

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 would a pilot want to catch 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.

How high above the earth’s surface is the jet stream?

Jet streams are currents of air high above the Earth. They move eastward at altitudes of about 8 to 15 kilometers (5 to 9 miles).

How fast can the jet stream go?

Jet streams vary in height of four to eight miles and can reach speeds of more than 275 mph (239 kts / 442 km/h ). Jet streams occur in both the Northern and Southern Hemispheres.

What happens when an airplane flies with a jet stream at its back?

Just the opposite occurs when an airplane flies with a jet stream at its back. Fuel and money are saved because the wind pushes the plane along. If you have ever flown in an airplane, you probably have experienced something called turbulence. Turbulence causes the bouncing, shaking feeling of the airplane.

Why is the jet stream choppy or turbulent?

The wind currents along the edges of the jet stream are choppy or turbulent as high-speed air meets more slowly moving, nearly stationary air (about 20 m.p.h.). When a plane flies through this it bounces around.

What is a jet stream and where are they located?

Jet streams are located about five to nine miles above Earth’s surface in the mid to upper troposphere — the layer of Earth’s atmosphere where we live and breathe. Airplanes also fly in the mid to upper troposphere. So, if an airplane flies in a powerful jet stream and they are traveling in the same direction, the airplane can get a boost.

Why are jet streams important to the aviation industry?

Because of their strong winds, jet streams play an important role in the economy of the aviation industry. When an airplane flies into a jet stream for any period of time, extra fuel must be used.
