To get to the United States, you have to go through Europe, why not go directly to the east?

First, in fact, it is mainly determined by geographical location, and secondly, due to security factors, these reasons determine that you need to take a detour when flying to the United States. The Earth is an ellipsoid, slightly flatter at the equator and flatter towards the poles. Then we can fly along high latitudes to shorten the flight distance.

In addition, the Bering Strait polar climate belongs to the westerly wind belt, and we can save time and fuel by having a tailwind.

Second, we draw an arc of flight on the earth according to the flight path, and then directly connect China and the United States through the Pacific Ocean. By comparison, we can intuitively see that the route directly east through the Pacific Ocean is longer. International flights require flying over national airspace, which involves the issue of "freedom of air access".

In particular, each country has its own security no-fly zones. Therefore, in order to determine the route, fly over the airspace of a country, or repair, refuel or transit in a country, it must negotiate with that country and cannot fly without permission.

3. Even if there is a fixed route, the airline will report the route to the domestic countries the day before the flight departure to avoid accidents. As a result, civil aircraft cannot travel freely and fly freely. To ensure flight safety, the international air traffic control department also requires that passenger aircraft flying across the ocean be equipped with a twin-engine system to cope with engine failures flying over the ocean.

At the same time, the climate over the Pacific Ocean is changing rapidly, making it easy to form ocean hurricanes, posing a huge risk to aircraft flights. Therefore, domestic flights try not to fly across the ocean, but mostly choose to fly along land.

Therefore, after many considerations, the final route to the United States was decided, which is a suitable route both in terms of economy and safety performance.

From China to the United States, the airplane's route is not directly eastward across the Pacific Ocean, but north through Europe and then to the Americas. Mainly because of the difficulty of installing radars in the Pacific Ocean,For safety reasons, the aircraft had to fly around the north in the radar coverage area, and in practice the distance to the Americas was about the same as flying across the Pacific Ocean

First of all, the car is driving on land with repaired roadsWhen an airplane flies in the sky, it must also fly according to the route developed in the air, especially civil aircraft, otherwise, the destruction of the plane and the death of people are a matter of every second. If the airway is to be developed in the air, it must meet some necessary hard conditions, the most important of which are the following:

First, the waterway to be developed must be a place that can be covered by radar. Otherwise, the state of the aircraft flying in the air cannot be controlled by the ground, and it is difficult to issue instructions to deal with sudden dangers in time once a dangerous situation occurs. Because there is very little land in the vast Pacific Ocean, it is particularly difficult to install radar.

Failure to meet this requirement will not lead to the development of routes.

Secondly, the shipping lanes must avoid areas of military activity.

Third, the meteorological conditions of the place where the waterway passes must meet the conditions for aircraft flight. At all stages of flight, an aircraft is constantly affected by meteorological conditions, and airflow is the most important factor. Factors such as air temperature, air pressure, thunderstorms, atmospheric turbulence, air jet streams, wind direction, and wind shear will all pose a deadly threat to aircraft.

In the above two points, because of radar coverage and meteorological conditions, so far, no direct route from China to the United States and transverse Pacific Ocean has been developed, so it can only fly around the north, which is the main reason.

Secondly, flying around the north to the United States, I intuitively feel that it is far away, but in fact, it is not. Because the earth is a sphere, if the circumference of the equator is measured, the total length is about 40,000 kilometers. But if you measure the circumference at 60 degrees north latitude, you will find that it is much shorter than the circumference of the equator.

There are two oceans directly to the east, which is a long distance, and the route to Europe in the past is convenient, takes less time, and is also safer, so it will not be affected by too many cold and warm currents.

First of all, a direct flight east to the Pacific Ocean takes 180 degrees, which is farther than Europe, so in order to save costs, choose a more cost-effective route. In addition, the Pacific Ocean is endless and the climate is changeable, so it is also for safety reasons to fly through Europe.

Directly to the east, there is a large Pacific Ocean, and there is no airport where you can temporarily land in case of extreme weather.

First of all, the earth is round anyway, and then the plane is a thing that if you can pass over land, it will feel more comfortable if you really need supplies.

There must be reasons and reasons for the route to be set up in this way, probably because of the consideration of safety issues, cost issues, personnel travel problems, and so on.

This is because such a route passes through Europe, and if there is no fuel, the aircraft will be able to supply fuel in a timely manner, while if it directly crosses two continents, it will lead to a lack of fuel.

This is determined by the geographical location, not how you want to go, just like Magellan sailed, slowly discovering the nearest road.

Flights to the U.S. go through Europe, which is a fixed setting of routes that work with all routes. It's not a straight line.

Europe is northeast of the United States!

Europe is in the Eastern Hemisphere, and the United States is in the Western Hemisphere, so Europe is in the East of the United States;

Most of Europe is between 40 and 60 degrees of latitude in the north of Zen, while most of the United States is between 30 and 50 degrees, so Europe is in the northern part of the United States.

Synthesized Europe in the northeast of the United States!

Of course, it's closer to Dongwu Chengou.

Beijing, for example, is about 9,300 kilometers from the west coast of the United States, while Ukraine is only 6,400 kilometers from Eastern Europe.
