Why do some planes fly from the sea to their destinations, but they have to fly around from land?

Nowadays, everyone's living conditions are getting better and better, there are more and more opportunities for travel, and taking a plane has become a more daily way to travel. I don't know if there are any friends who flew from Shanghai to Yantai, have you noticed that the planes on this route fly directly to Yantai without passing through the sea. So, doesn't this extend the flight of the plane?

In fact, the route from Shanghai to Yantai will be detoured, and there is a reason why it does not fly from the sea. First of all, the safety of flying from land is higher. We often see airplanes malfunctioning while flying.

If you fly over the ocean, there is no airfield where there are planes to alternate landing, and if the plane breaks down, then the consequences are unimaginable. If the aircraft is flying on land, even if it breaks down during the flight, it can notify the nearest airport to make a forced landing, and the safety is greatly improved.

The second reason is that the wind speed in the sea surface has a great impact on the flight of aircraft. When the aircraft is flying, the wind speed is higher and will affect the operating expenses of the aircraft. If the flight is headwind, it will consume more fuel, and if it is downwind, it will consume less fuel.

The route from Shanghai to Yantai is windward, and in order to avoid fuel consumption and maintenance, it will avoid flying on the sea surface. Moreover, when the plane is flying, the most worrying thing is that the wind speed is large, which will cause the fuselage to fly unstable, and even sometimes, it will cause the plane to roll over. Therefore, airplanes will prefer to detour when flying and try not to choose to fly from the sea.

In addition to safety factors, the delineation of aircraft routes also needs to consider the stopping points of aircraft. Many routes pass through many small cities, so you need to consider passengers with other stopovers when flying. The route allows passengers to take the route from Shanghai to Beijing when the planes in other small cities break down, or when there is a problem with the overlapping routes.

This greatly increases the utilization rate of the aircraft, reducing the airline's fuel costs, crew salaries, and aircraft maintenance costs.

In fact, the route of the aircraft can not be arranged at will, if the route coincides with other routes, the flight consequences will be very serious. Although there are no obvious roads in the air like those on land, the flight path and altitude of the plane will be set before the flight, and once the plane is about to collide, if it cannot be adjusted in time, it can only end up being destroyed and killed.

I think it's mainly for a safe landing, because in the event of some natural disasters, you can make an emergency landing over land.

Because the weather on the sea is very changeable, and unlike the land, there are many beacons that can be set up, and there is almost no chance of survival in the event of an accident.

Because there are many areas and regions where you can't fly in, it is very normal for such a phenomenon to happen.

Because if something dangerous happens at sea, there is nowhere to land, and it is very dangerous.

Because the earth has an inertial force called the "geostrophic deflection force", if the plane has been flying in a straight line, it will deviate from its original direction under the action of this force. It's hard to understand that. If you think about the fact that the earth is moving when the plane is flying, it is not only rotating, but also revolving.

You can't get to the place by flying in a straight line.

Are you saying that the wrecked plane in France fell into the sea and why it couldn't go on. Because the plane has broken down and can't fly anywhere. If it is a normal plane, it can also walk in the sea, but not too fast.

Is it called flying in the sea in the sea is called swimming in the sea If you fly in the sea, it is not called an airplane If it is underwater it is called a submarine Haha There are many planes that take off on the water For example: our "Water Bomb-5"! It's taking off and landing on water.

Are you saying that the wrecked plane in France fell into the sea and why it couldn't go on. Because the plane has broken down and can't fly anywhere. If it is a normal plane, it can also walk in the sea, but not too fast.

There are also planes that can take off and land at sea, but there are very few, and they are usually small planes.

Seaplanes can "fly" at sea.

When you can make the ship fly in the sky, the plane can fly in the sea.

An airplane has two basic characteristics: one is that it is denser than air, and it is powered to move forward; The second is that the aircraft has fixed wings, which provide lift and allow the aircraft to soar through the sky. Those who do not possess the above characteristics cannot be called an aircraft, and these two are indispensable.

Because, the power plant that sails in the sea cannot be called an airplane. So, the plane will not fly in the sea. Seek adoption.

Yes, there are sea planes, but they are not popular, and the speed is not good.

In the sea is swimming, if the plane is called a pleasure plane then it is okay

Seaplanes can also fly in the sea! You're not right.

The explanation is more complicated.

Due to the shape design of the airfoil, the airflow through the upper surface is longer than the distance through the lower surface, resulting in the flow speed of the upper surface is faster than that of the lower surface, and the east pressure is inversely proportional to the speed, so the pressure of the airflow on the lower surface is greater than the pressure on the upper surface, so the aircraft can fly, which is a more popular explanation. Actually, lift is also related to a lot of professional things.

The ship mainly depends on the buoyancy of the water, and of course it may also be related to the speed.

Because the air on the upper surface of the aircraft moves faster than the air on the lower surface. According to fluid mechanics. The faster the flow rate on its surface.

The less pressure you are subjected to. Therefore, the pressure on the surface of the aircraft is less than the pressure on the lower surface, so its resultant force is upward, such as the plane can fly. Of course, the magnitude of the force should be large enough.

Reasonable design of the aircraft shape can meet the above conditions. You can do your own rubber burial experiment, you take a piece of paper, you blow on the top surface of the paper, and you will see that the paper will float, and the plane can fly like that.

For a fixed-wing aircraft, when it flies at a certain speed in the air, according to the principle of relative motion, the movement of the wing relative to the air can be seen as the wing does not move, and the air flow flows through the wing at a certain speed, because the wing is generally asymmetrical, the upper surface is more convex, while the lower surface is relatively flat, the air flow through the upper surface of the wing is faster, and the air flow through the lower surface of the wing is just the opposite, and the flow rate is slower than that of the upper surface. According to the basic principles of fluid mechanics, the pressure of the atmosphere is greater than that of the slow flowing atmosphere, and the pressure of the fast flow is smaller, so that the pressure on the lower surface of the wing is higher than the pressure on the upper surface, in other words, the pressure exerted by the atmosphere on the lower surface of the wing (direction upward) is greater than the pressure applied to the upper surface of the wing (direction down), and the pressure difference between the two forms the lift force of the aircraft.

When the wing of the aircraft is symmetrical and the airflow flows along the axis of symmetry of the wing, the airflow does not generate lift because the shape of the two surfaces of the wing is the same, so the airflow velocity is the same, and the pressure generated is the same. But when a symmetrical wing moves through the air at a certain angle of inclination (known as the angle of attack or angle of attack), a similar flow phenomenon occurs with an asymmetrical wing, making the pressure on the upper and lower surfaces inconsistent, which also generates lift.

I thought it was a real plane, but you were a model airplane, and it could only fly on the ground because the power of its engine was not strong and it couldn't be driven.

It's that the engine is not installed, is it that there is no power?
