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 are flights shorter one way?
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 do planes fly lower sometimes?
Why do the aircraft fly so low? Aircraft have to fly low in order to properly line up with the runways and execute safe landings. Aircraft may, however, appear to be lower than they actually are because their large sizes make them look closer.
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.
Does the Earth rotation affect air travel?
The rotation of the Earth has no direct significant effect on flight times in either direction.
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.
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 planes fly at 35000 feet?
A balance between operating costs and fuel efficiency is achieved somewhere around 35,000 feet, which is why commercial airplanes usually fly at that altitude. Commercial airplanes can climb to 42,000 feet, but going beyond that can be precarious, as the air starts to become too thin for optimum flight of the airplane.
Why do planes fly low at night?
But one of my friends claimed the reason why we are supposed to fly at a lower altitude to prevent from hypoxia is that at night there is higher pressure near the ground which makes fewer air molecules at high altitude at night than daytime.
Can planes fly over Everest?
Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.
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.
Can a plane fly faster than the Earth rotates?
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.
Why can’t a plane fly slowly and let the Earth pass underneath?
The reason an airplane can’t just idle and let the ground pass underneath is the same reason as why a ball dropped from a tall tower lands at the base of the tower and not next to it. … In order to fly east, the plane increases its speed relative to the surface of the Earth and begins to overtake it.
Why don’t we feel the Earth spinning?
Bottom line: We don’t feel Earth rotating on its axis because Earth spins steadily – and moves at a constant rate in orbit around the sun – carrying you as a passenger right along with it.
Can planes fly over North Korea?
The US prohibits flights across all North Korean airspace, including the oceanic part of the ZKKP/Pyongyang FIR over the Sea of Japan. Several other countries have airspace warnings in place which advise caution due to the risk posed by unannounced rocket launches.
Why do planes not fly straight across the Atlantic?
Ask the Captain: Why don’t planes fly in a ‘straight line?’ … Answer: It is shorter to fly the Great Circle route than a straight line due to the circumference of the earth being so much greater at the equator than near the poles. Q: Captain, I often follow trans-Atlantic flights between Europe and the USA.
