Why do planes have to go around the airport during take off and landing?

When the plane took off, it didn't feel so fast, so it taxied first, and then said that the flight was the plane raising its head to fly, and then spiraling, taking a plane is different from a train, 40 years of reform and opening up, for the sake of safety. Like ordinary people going out to travel to plan the itinerary, when the plane is ready, can not literally fly, when flying to a certain height, the plane must first adjust the flight attitude to ensure that it enters the fixed route smoothly, otherwise if it is not adjusted, the plane is likely to fly into other routes, and it is easy to crash, so we see the plane hovering in the sky.

Its purpose is to enter the planned route. It has been used for long-distance passenger transportation, many friends should have also sit, and the airport of the plane is generally built in a proper location away from the city, one is because there can be no too high buildings around the aircraft, and the other is that there is a lot of noise to the aircraft, and now the large aircraft are jet fixed-wing aircraft.

Mainly, such a plane has to taxi long distances to take off and land, which is too expensive in the center of the city.

The reason is the weather, sometimes there is fog at the local airport, if it affects the observation, the plane will wait for the opportunity on it, or the rain, snow and wind, the plane will evaluate on it, and either continue to land, or have to be diverted to other airports. We also often hear that planes are delayed or cancelled due to weather conditions, because the take-off and landing of planes have relatively high requirements for the weather, and also for the safety of passengers' lives and property. The plane does not have to go around the airport when taking off and landing, it is generally necessary to turn around when landing, but not necessarily when taking off.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Because the plane is louder when landing, this can reduce the noise, and then you can better understand the local weather conditions and wind direction, you can achieve the effect of landing safely, and then you have to observe the surrounding environment.

To find a suitable place to stay, you need to observe the situation on the airport apron, you need to inform the airport staff that the plane is going to fall, and in order to stabilize the various functions of the aircraft, look for the staff who will lead the inscription.

Because this can provide a buffer, it can also avoid the occurrence of a crash, and it can also avoid a lot of unnecessary trouble. It can also allow passengers to land without much discomfort.

The purpose of idling around is to observe the weather conditions and the surrounding environmental conditions, to ensure that Shun can fly safely, and to wait for orders from the command station.

Airliners circle in the air, the term is circling.

There are a variety of reasons.

1.There are many planes landing in front of the destination airport, circling and waiting to land.

2.There is a controllable situation at the destination airport, which can be restored in a short period of time and temporarily circulated.

3.The weather conditions at the destination are complicated, observe the changes, and decide whether to land.

4.Runway tenure issues.

5.The overall weight of the flight is too heavy, which consumes fuel and reduces weight.

6.There are technical problems with the flight, which affect the landing and need to be investigated.

The plane cannot be in the sky all the time, and it is impossible for the plane to keep circling in the sky and not landing, because it still needs to land when the oil in it is always used up, and then it needs to be overhauled and the engine needs to stop working for maintenance.

Waiting for the landing command from the tower, the runway is usually still occupied, and there are more urgent aircraft taking off and landing.

If the plane keeps flying in the sky and doesn't land, it's a show, otherwise he wouldn't have done it.

Why do planes take a spin around the airport when they land? The plane does not have to go around the airport when taking off and landing, it is generally necessary to turn around when landing, but not necessarily when taking off.

1. When taking off: Generally speaking, take-off will not go around a circle, but because the plane takes off and lands against the wind under normal circumstances, sometimes it may be supposed to fly south, but because it is blowing the north wind, the plane will take off to the north.

2. When landing: the pilot has a term called "flying five sides", of which the first side is called "departure side" (that is, the meaning of take-off), the second side is called "crosswind side", the third side is called "downwind side", the fourth side is called "bottom edge", and the fifth side is called "approach side" (the meaning of landing), in fact, it forms a rectangular route, but the height of each side is different. "Flying five sides" is a flight procedure, also known as "take-off and landing routes".

This flight procedure is a visual flight procedure, which is prescribed to ensure the safety and orderliness of the flight, and is a procedure that is common all over the world.

Both passenger planes and fighter planes take off and land in accordance with the "five sides," and "flying five sides" is the basic flight essentials that must be mastered in the aviation school. "Flying five sides" is a rule for safe take-off and landing, and all pilots in the world must follow the rules, just like driving a car and driving according to the traffic rules. Left turns must be turned on beforehand and then enter the left turn lane.

The plane landing must strictly adhere to the pentagonal system, occasionally encounter a non-busy airport may also be able to land on three sides, when encountering a busy large international airport, it must be lined up on five sides to land. One side and five sides are the take-off and landing side, the second side is the turning and climbing side, which is also called the crosswind side, and the third side is the climbing and cruising side, and you can turn on the automatic driving to enter the destination range at this moment.

You are talking about the take-off and landing routes, and taking a circle over the airport is more about the weather, especially when the visibility is not good, the take-off and departure point is a long-distance navigation station. When landing, follow the signal of the navigation station to do a cloud-piercing flight. People who take a lot of planes will feel that when the weather is good, a certain route arrives in an hour, and when the weather is bad, it will take less than an hour and a half.

Because of the air over the airport, it takes about twenty minutes to land through the clouds.

To be on the safe side. Many people feel that taking a spin around the airport every time they take a plane is a tedious step, but safety is the most important.

The first is to confirm the safety of the landing place at the airport and ensure that there are no personnel. The second is to provide a buffer for the aircraft, which is more conducive to the smooth landing of the aircraft.

Because the plane needs to determine the safety of the ground when landing, it must hover in the air first and wait for the ground to send a safety signal before landing.

Why does an airplane make a circle around the airport when it takes off or lands? There's a lot of emphasis on this! Why do you have to go around the airport when the plane takes off or lands? Is there anything else to learn from this?

Because there are a lot of planes that have landed, they have to land one by one. And they hover just to land other planes and wait for orders to land.

The direction of the runway is fixed, but the direction of the wind is constantly changing. Therefore, when the aircraft takes off and lands, it is not always headwind, and it is often carried out in crosswind conditions.

Due to the slow speed and poor stability of the aircraft during take-off and landing, the aircraft may deflect in case of strong crosswinds, which increases the difficulty of the pilot's operation. Therefore, when the aircraft takes off and lands in crosswinds, the pilot should pay special attention to correcting the deviation, otherwise there will be a danger of taxiing off the runway.

Control system:

The aircraft control system is used to transmit the pilot's control instructions and change the flight state from the pilot's cockpit to the control surfaces such as the horizontal tail, aileron, and rudder. Early manoeuvring systems were purely mechanical manoeuvring systems consisting of tie rods, rocker arms (or steel cables). Modern aircraft use a lot of automatic control devices in the control system, so it is often referred to as the flight control system.

An aircraft powerplant is a device used to generate pull (propeller aircraft) or thrust (jet aircraft) to move an aircraft forward. The power plant with thrust vectoring can also be used for maneuvering flights. Most modern military aircraft are jets.

The power plant of jet aircraft is mainly divided into two categories: turbojet engines and turbofan engines.

There are several main reasons for hovering in the air when landing.

The first is because the route of the plane is fixed, but the plane flies back to the airport from different directions, and the pilot has to land according to the prescribed route, so hovering in the air is to adjust the angle, adjust the direction and then land;

The second reason is that there happened to be a lot of planes at the time of landing, and there was no place at the airport, so the pilot could only hover in the air and wait for the arrangements of the relevant departments before landing.

The last reason may be that the plane is malfunctioning when it is preparing to land, and the pilot should hover the plane in the air for a while to consume as much fuel as possible, as this can effectively reduce the weight of the aircraft.

In this way, the danger of the aircraft may be reduced a lot, but in the end this reason is rarely because the aircraft is very safe, and the probability of failure is very low.

Why sometimes planes keep circling before landing With the continuous development of science and technology and the improvement of people's quality of life, more and more people list airplanes as one of the indispensable means of transportation. Passengers travelling by air may sometimes find that the plane arrives over the airport and does not land, but instead hovers in the air, why is that? Today, the tea house will introduce to you why the plane keeps circling over the airport before landing.

That. 1. The direction of the runway is fixed, but the aircraft approaches the airport from all directions, and it must approach and land in accordance with the glide line stipulated by the air traffic control center, so some aircraft must first turn around the paddock and only run to the approach landing after adjusting the direction; That.

2. Sometimes there are many planes landing, and the glide line and runway are occupied, and the landing planes have to accept the command of the air traffic control department, circling and waiting to land in order; That.

3. If the weather is bad and the visibility is low in the sky above the airport, the aircraft will also circle over the airport and wait until it receives the order of the air traffic control department to allow landing, and then adjust the direction to enter the landing.

What is the reason why planes hover in the air before landing? Today is a long time to see.

The first reasonThe second reasonThe third reasonBecause the runway of the aircraft is fixed, the planes often fly back from all directions. If you land directly, you may be in the wrong direction or in the wrong place. Therefore, the plane needs to be adjusted in a circle before landing slowly.

After reading this, we can know the real reason why the plane is circling, so the step of circling in the sky before the plane takes off must not be omitted, this is for the safety of every passenger.

The take-off direction and landing direction of the airport are to be changed, and the terminal is at the start of the runway when taking off, so there is no need to turn, on the contrary, you need to taxi to the start of the runway to take off. The same is true for landing, if the flight direction is the same as the landing direction of the runway, you don't need to fly a lap, but you must fly a lap. It's as simple as that, where did those reasons come from.

Fly five sides, there is also the problem of air traffic control, you have to avoid other planes, otherwise you will not be able to collide.

This is because it depends on whether there is a problem with the aircraft, whether the fuel of the aircraft is sufficient, and whether its system is well connected to the company to ensure the safety of passengers. We're going to do a series of systems to inspect the aircraft.

When the plane takes off, it needs to make a circle around the airport first, for the sake of safety, for the purpose of measuring the aircraft's trajectory and accelerating better.

Swinging around can make the plane flexible, the plane is a special tool, generally not so flexible, there may be people who can't stand it, and the fuselage itself will not be flexible enough.

1.Take-off and landing are the most dangerous part of the flight, and the main reasons for turning off the lights are as follows: 1 Passengers are requested to help observe the external environment, especially those near the wings, and if they see anything wrong, such as engine smoke or flaps not functioning properly, passengers can report to the captain immediately. 2 Because it is the most dangerous for the aircraft during take-off.

If there is an accident, our eyes are aware of the light outside.

It is easy to find the situation in the outside world 2The aircraft is the most dangerous part of the whole flight during take-off and landing, and the main reasons for pulling up the visor are as follows: It is not to open the window, but to open the visor. 1 Passengers are requested to observe the external environment, especially those near the wings, and report to the captain immediately if they see something wrong, such as engine smoke or flaps not functioning properly.

2 Because it is the most dangerous for the aircraft during take-off.

If there is an accident, our eyes are aware of the light outside.

It is easy to find the situation in the outside world 3 If an accident occurs, the ambulance personnel who rush to support can observe the environment inside the aircraft through the window and speed up the rescue work. Although it seems like some trifles.

But in fact, the consequences of not doing so can be very serious. Cabin crew members are not looking for nothing to do.

To embarrass passengers.

Just for everyone's safety.

Please don't challenge them the next time you fly! image

Listen to it for the first time! Interesting and interesting

Pull the window leaves up.

It's a pull buried. Shut it off.

Instead of opening. If it's right.

I want someone who really understands to explain.

The most dangerous part of an airplane's wings during take-off and landing to support the wind may come loose during take-off and landing"The window leaves are to be pulled up to allow the flight attendants and passengers to see what is going on with the wings. If there is a loosening situation, you can immediately notify the captain. Although it's not too detailed, I hope it can help you!
