Shenyang airport weather Dan is true and false

Recently, the problem of flight delay has been heated up in China. Undoubtedly, the Opinions on Compensation for Flight Delay issued by the Civil Aviation Administration of China has played a great role in improving airlines' services and reducing flight delays. However, this document makes the vast number of passengers feel that they have got a sword of honour, and the excessive acts such as making a scene at the airport, occupying the plane, and insulting the crew and service personnel have appeared frequently in major airports in China. It is not uncommon to ask for high compensation and refuse other service measures proposed by airlines, which leads to the damage of airlines' reputation, serious loss of interests and frequent negative news of flight delays in major media.

Flight delay status:

Civil aviation: the flight has been delayed. Usually, there are only four words to explain, which are listed as follows: weather, air traffic control, mechanical failure, aircraft deployment, and simple refining. This is actually a very complicated situation. Objectively, there are uncertainties of poor information transmission and delay. All along, civil aviation thinks it is unnecessary to explain, or it is very troublesome for passengers to understand. Delayed service is simple and blunt, lacking in detail and consideration.

Passenger: For most passengers, flying is safe, fast and comfortable. But if there is a flight delay, this desire will undoubtedly be greatly reduced, and even people will feel depressed and angry. At this time, the delayed information is no longer known or the time is delayed. If you don't know when the delay will be, passengers will definitely not accept it and will be prone to excessive behavior.

Media: whenever the flight is delayed, passengers will always introduce the situation to the media; In order to create a sensational effect, the media made a sensational news, and the airlines did a poor job in communication with the media. Even if a responsible media interviewed the relevant civil aviation units, it is a pity that the people responsible for communicating with the media and the public are usually sitting in their offices, but they are full of shelves, and in fact they are amateurs who don't know much. The answer is usually vague or too simple, which is not enough for the public to fully and accurately understand the facts, and it is getting darker and darker.

Here, I will introduce the reasons for the delay and explain the common delays. I hope passengers can understand the current situation and communicate more soberly and calmly through legal channels. Impulse is definitely not the best way to solve the problem.

Cause analysis of flight delay

Weather reason

At present, the weather is the main reason for flight delay. It is generally believed that the bad weather is obvious and passengers can understand the flight delay, but it is not.

At present, the explanation of civil aviation for the delay caused by bad weather is that the weather can not meet the flight standards and can not take off on time. General civil aviation service personnel often don't know exactly the impact of bad weather on flights like passengers. From the passenger's point of view: bad weather means strong wind, heavy rain and fog, planes may not be able to take off and land, and flights may be delayed. However, this understanding is one-sided and will lead to many misunderstandings. Think that civil aviation is deceptive, especially some flights can go and some can't.

The simple word "weather reason" actually contains many situations: the weather conditions at the departure airport are not suitable for take-off; The weather conditions at the destination airport are not suitable for landing; Meteorological conditions of flight routes are not suitable for overflight, etc.

In order to ensure flight safety, there are many meteorological standards that meet the requirements of flight, take-off and landing. Here, first of all, introduce where the weather conditions affect a flight, which will help you understand.

-Weather conditions at the departure airport (visibility, low-level clouds, thunderstorm area, strong crosswind):

-Weather conditions at the destination airport (visibility, low-level clouds, thunderstorm area, strong crosswind):

-Meteorological conditions on the flight route (high-altitude thunderstorm area):

-Unit status (technical level of the unit, analyzing and mastering the current weather and trends to make professional decisions)

-the condition of the aircraft (the aircraft's safety standards for meteorological conditions and the failure of some airborne equipment on the premise of safety make the aircraft unsuitable for flying in such weather conditions)

-Subsequent situations caused by bad weather (mostly damage to airport navigation facilities, unqualified runways such as icing, serious water accumulation, etc.). )

Common situations to dispel doubts:

Question 1: The city where the destination airport is located has good weather conditions and good visibility. Why is it still delayed because of the weather?

A: The weather in the destination city is good, there is no heavy rain or strong wind, and the passengers are very confused. It is still delayed. Just because the weather in the city where the destination airport is located is good does not mean that the airport is suitable for plane landing. Low clouds and thunderstorms cover the airport take-off and landing passages, which is a common factor leading to such delays.

Knowledge points: In order to ensure flight safety, even if the plane is in the automatic landing state, the pilot must be able to see the runway and the ground completely at a certain height (generally 60 meters) before landing. If you can't see the runway at this time, you are not allowed to land.

Question 2: The city where the destination airport is located has good weather conditions and good visibility, and the airport is also taking off and landing normally. Why is it still delayed because of the weather?

A: This situation is often because the meteorological conditions of the flight route are not suitable for flying over, for example, in a thunderstorm area, in which case the plane can only wait on the ground.

Knowledge points: once there is a thunderstorm area on a narrow route, it can be bypassed under certain conditions. However, due to flight safety and national defense needs, civil aviation routes are strictly restricted, and there is little room for flight and maneuver. When the thunderstorm area is large, this method will not work?

Question 3: Why are some flights to a certain place available, while others are told that they can't because of the weather?

A: There are many possibilities for this situation. First of all, it must be clear that the standard of aircraft take-off and landing is related to the model. The specific safety standards set by the same aircraft in different airlines may also be different, and the captain will make different decisions according to the current weather and trends. It depends on the captain's decision after judging the state of the plane, airport, weather, etc. The Civil Aviation Law stipulates that "if the civil aircraft, airport and meteorological conditions are found not to meet the requirements and flight safety cannot be guaranteed, the pilot-in-command has the right to refuse to fly".

Question 4: Why didn't you tell me that I couldn't land at the destination airport because of the weather, and I had to alternate to other airports or return, and some planes could land normally?

A: Although the meteorological department of civil aviation relies on advanced equipment to continuously issue more accurate weather trend forecasts to facilitate flight operation and scheduling, the weather conditions are constantly changing and it is difficult to accurately judge. This will lead to a sudden deterioration of weather conditions when landing, resulting in the inability of the plane to land. For safety reasons or fuel shortage, the plane will have to alternate to other airports.

The weather is constantly changing, and it may be bad weather for a short time. Five minutes ago, the weather allowed the plane to land, five minutes later, and your plane just caught up with the bad weather conditions and could not land. This is a very common phenomenon. At the same time, as mentioned above, when the weather is on the edge of the standard, it is up to the captain to decide whether to land. The captain thinks that the weather is not suitable for landing at other airports or returning to other airports, and should absolutely support it.

When the flight is delayed due to weather, passengers should pay attention to the following points:

The weather reason not only refers to the weather conditions in the city where the destination airport is located. Aircraft take-off and landing are not afraid of strong winds and heavy rain. The key meteorological factors are visibility, low clouds near the airport take-off and landing passages, and strong crosswinds. It is normal for your flight to be delayed due to the weather.

Air traffic control:

In this case, the explanation of civil aviation is even less, because it is considered that it is not its own reason and it is impossible to change this situation. It can only wait for the notice honestly, and it is useless for passengers to worry.

From the passenger's point of view, there are few planes on the tarmac. Where does the traffic come from and what does it control? Oh, everything is normal at the destination airport, and there is no control at all. In fact, flow control is invisible to ordinary passengers. On the surface, everything seems to be all right.

"The sea is wide and the fish jumps, and the sky is high and birds fly", but in reality, civil aviation planes, like cars on the ground, are restricted and influenced by many factors. In short, civil aircraft take off, land and fly in limited space, limited time and limited conditions. At present, the air traffic in some busy airports is overloaded, and it is normal for planes to glide on the ground or even wait for a long time when they leave Hong Kong.

There are two main reasons why air traffic control affects flights.

1. Flow control: In recent years, China's civil aviation has developed rapidly and the number of flights has surged. However, the development of corresponding ground facilities, navigation equipment and service guarantee is slow, and the route structure is unreasonable, which can not adapt to the rapid development of current civil aviation. Especially for reasons such as ensuring national defense security, China has imposed strict restrictions on airspace, and there are many restricted areas in the air. The military is responsible for organizing the implementation of national flight control, and the adjustable redundancy in civil aviation is very small. What we are talking about here is normal flow control. In fact, there are many reasons for traffic control, such as some unexpected situations in the air or at the airport, which will not be introduced here.

2. Air Force activities: This situation involves national defense secrets and often comes suddenly. In short, control and related civil aviation flights will be affected, either waiting on the ground, waiting in the air or returning or landing at other nearby airports. In this case, you can only wait, there is no reason and no estimated time, everything is top secret. Take Xiamen as an example, the proportion of flight delays caused by this situation is not small, especially in the case of military exercises in the southeast coast and tense cross-strait relations. Generally speaking, air force activities will be carried out during the day when the weather is clear. Generally speaking, it mainly controls the outbound flights from Xiamen to Shantou, that is, international flights from Xiamen to Southeast Asia, regional flights to Hong Kong and Macao, and flights to Guangzhou, Shenzhen, Haikou and Kunming. In severe cases, flights in these directions will also be affected, or they will alternate nearby or return. The control time is as short as half an hour and as long as three or four hours. Once the control is lifted, there will often be a large number of aircraft jams in the airspace, which will continue to cause delays. Once the control is implemented, almost all flights at the relevant airports will be disrupted that day, leaving civil aviation at a loss.

Common situations to dispel doubts:

Question 1: After the plane boarded the passengers, the doors were closed and everything was ready. Why haven't we left for a long time? Why don't the planes next to us leave, so we can't leave?

A: Obviously, you have encountered flow control. At this time, the plane is waiting in line. The crew will generally explain to passengers that they are currently under flow control and waiting for air traffic control instructions. Other aircraft can leave Hong Kong normally, and the destination and direction may be different, which is not affected by this flow control.

Question 2: Everything is ready for the plane. After sliding for a while, stop and go. Why didn't you take off for a long time?

A: The plane should be ready to take off by this time. The airport runway is limited. At this time, there are many planes that may land and take off, and they are entering the runway and taking off at a certain safe interval. In the rush hour of some busy airports or general airports, air traffic is overloaded, and so is ground traffic. It is normal for the plane to slide on the ground when it leaves the port and even wait for a long time.

Question 3: Since there is flow control, why not board the plane late and stay in the narrow cabin for a long time?

A: Traffic control is a common thing, and it usually doesn't take long, but there may be many flights in the same direction. When your flight is ready, you can apply to the control department as soon as possible. The earlier you apply, the shorter the waiting time, which is the same as queuing for shopping at ordinary times. If you wait too long, you may not meet the normal flow control! In addition, due to other reasons, it is expected that the control is not in place, which requires the aircraft to be ready as scheduled and the airspace may be opened at any time. You can't wait until the control is lifted before boarding the plane. When you are ready, you may encounter the next round of control.

Question 4: Why did you wait for a long time because of the flow control, and then said that you couldn't leave, so you had to get off the plane and wait in the terminal, or even prepare to take off and slide back on the runway? Isn't this annoying?

A: There is an estimated time for normal flow control, and the crew will decide whether to wait after boarding or in the terminal according to the situation. However, as mentioned above, in some cases, air traffic control has no expected time and may be released at any time. The airspace opening time may be short, so the aircraft needs to be prepared first. If the time is too long and there is no clear news about when to take off, passengers will wait for a long time before getting off the plane and waiting in the terminal. The situation is constantly changing. When an accident happens in the air or at the destination airport, it may also cause your plane to take off on the runway and have to slide back and wait.

With regard to air traffic control delayed flights, passengers should pay attention to the following points:

When we arrived at the air traffic control, the passengers were in a hurry and the crew were in a hurry, but there was no way. I can only wait patiently. I can't wait long. It's not that the crew lied to you. I really don't know.

Mechanical failure:

Passengers have to get off the plane when they get on the plane or the plane breaks down. Sometimes, after the plane takes off, they are told to return or land nearby. Under these circumstances, it is understandable that passengers not only have to endure the inconvenience caused by flight delays, but also worry about safety. Passengers are concerned about how long it will take to fix the fault. When passengers board the plane again, they are more concerned about whether the plane fault has been completely eliminated. This paper briefly introduces the general procedures of daily maintenance and post-fault maintenance of aircraft.

First of all, let passengers rest assured that the safety factor of aircraft is constantly improving and the aircraft is becoming more and more advanced. It has multi-layer redundancy and multiple backup systems in all important characteristics of the aircraft. The aircraft has a detailed regular maintenance plan, and the corresponding systems and equipment should be thoroughly inspected and replaced every once in a while. Even if the system and equipment work normally, according to the long-term maintenance experience, most hidden dangers will be dealt with in time in these routine inspections, but no matter how perfect and meticulous the routine maintenance is, there is no guarantee that the aircraft equipment will not suddenly break down, which can often be avoided by normal routine inspections. Maintenance personnel, crew members and advanced airborne computers will also monitor any situation of the aircraft at any time, and any problems that pose a threat to flight safety will be solved before continuing to fly. Of course, in order to ensure safety, it is worthwhile to completely eliminate hidden dangers, which will inevitably cause a certain degree of delay. After all, safety is the most important thing.

Once an aircraft breaks down during the flight mission, the crew should make necessary inspection and judgment according to the maintenance procedures, analyze the fault phenomenon, find the source of the fault, and then carry out corresponding troubleshooting work, such as replacing the faulty parts. After troubleshooting, it is necessary to fill in the relevant maintenance records, and it is also possible to carry out certain testing work to determine whether to repair. The whole troubleshooting process takes some time. Even some minor faults, there must be a set of strict maintenance and inspection procedures to ensure flight safety.

Generally speaking, if the plane is at the base of an airline, it will take a long time to deal with the fault, even if it is a major fault that is difficult to repair for a while, because it is easier to deploy at the base and the delay time will be shorter.

If the aircraft fault is located in an external station, there may be a lack of necessary maintenance equipment, spare parts and maintenance personnel in the local area. It is really hard to say how long the delay caused by this situation will take, which is related to the specific situation of the fault and the local maintenance ability. If it is difficult to eliminate major faults at one time, it will take a long time to send another plane.

Common situations to dispel doubts:

Question 1: Why do you have to prepare for takeoff or just tell the plane that there is a mechanical failure, and you have to slide back or return? How did you check it? Aren't you well prepared?

A: This is a matter of common sense. Like other equipment, some faults can't be detected at ordinary times. You don't know if they are good or bad without using them. You can only find problems during use.

Question 2: Why is it not clear to repair and expand the plane after it breaks down? Time is delayed, and it is not allowed.

Answer: It takes time to eliminate mechanical faults, and the maintenance department has a rough estimate. However, if new faults are found during the maintenance process or some unexpected situations occur during the maintenance process, the time will be extended.

After the fault occurs, it is impossible for maintenance personnel to know how long it will take to repair the fault in the process of finding the cause of the fault. At this time, passengers are anxious to ask how long it will be repaired, and it is difficult to get a satisfactory answer. Service personnel often handle things. After the maintenance personnel find out the cause of the fault, they will have an approximate troubleshooting time, and then they will inform the relevant departments to make corresponding preparations.

Question 3: Why is the plane repaired after it broke down and broken down after taking off, so it is an alternate flight or a return flight? Is it overhauled? Isn't this a joke about the lives of passengers?

A: First of all, the fault you encounter again is not necessarily just fixed, and there is no such thing as taking off without fixing it. Secondly, the repaired parts and equipment may fail again, which is unpredictable. Of course, it is also possible that the maintenance personnel did not find the source of the failure, which led to the same failure again after the surface failure equipment was repaired for a period of time.

Question 4: Why didn't the maintenance staff come to repair the plane when it broke down?

A: Maintenance personnel can test and replace the equipment in the cockpit or electronic equipment cabin. Maintenance after aircraft failure does not always require a large scene and a large number of maintenance personnel and equipment.

Of course, it is also possible that there is a lack of aviation materials or it is impossible to repair the aircraft. You may have to wait for spare parts of aviation materials or the base to send someone to repair it.

The main points that passengers should pay attention to about the flight delay due to mechanical failure are as follows:

The first priority of civil aviation is safety. Everything can be sacrificed to ensure safety. Time may be delayed during troubleshooting. This is not cheating. Is responsible for safety, but also for the majority of passengers.

Passenger reasons:

There are many reasons for flight delays, some of which are irresistible natural factors. It is worth noting that some human factors have become "new growth points" that cause flight delays. According to statistics, flight delays caused by passengers account for 3% of abnormal flights, which is almost the same as the number of delays caused by aircraft failures.

Common situations are:

Passengers arrive late after the flight check-in deadline.

For the convenience of passengers, airports and airlines will try their best to help these late passengers catch their flights smoothly, but this will inevitably lead to flight delays, and these high-quality services also encourage some passengers to be habitually late in some aspects.

Remind passengers that in order not to affect the whole flight operation plan, especially the current punctuality rate, these late passengers are more likely to accept the result that they are forced to change their follow-up flights by mistake.

After receiving the boarding notice, the passengers left without saying goodbye, which seriously affected the flight operation, especially the passengers who were directly stranded at the airport.

Because once a passenger fails to board the plane without saying goodbye or for other reasons, in order to ensure the safety of the majority of passengers, it is necessary to confirm that the passengers have not left anything on the plane, and conduct a comprehensive inspection of the cabin and all checked baggage. Even if the passengers have not checked their luggage, and in order to be responsible for the passengers, the airlines must unload the luggage delivered by the passengers from the plane to avoid the situation that the passengers and luggage are not in the same place. If you are a transit passenger, the implementation of this work will be very time-consuming because you have not handed in the specific baggage list.

Some passengers who often fly often have to wait until the plane takes off after receiving the boarding notice.

The passenger thinks that the plane will definitely wait for him after completing the formalities. In a busy airport, when the flight finishes boarding one minute in advance, the crew will apply to the air traffic control department for take-off one minute in advance, which will not only bring about take-off one minute in advance, but may take more than ten minutes or even longer. The author once encountered the situation that passengers boarded the plane late, the alternate team was ready to leave Hong Kong, and the weather deteriorated, which eventually led to the cancellation of flights and overnight detention. Airlines and passengers suffered huge losses as a result.

After check-in, passengers shop, read books, make phone calls and have meals in the terminal building, without paying attention to the boarding broadcast.

As a result, the airport keeps broadcasting to find someone, and the plane has to wait, which may eventually lead to passengers missing the plane.

International transit flights are delayed due to problems such as passenger documents when going through entry and exit procedures.

Customs border inspection and other relevant departments carry out strict entry-exit inspection according to regulations. For security reasons, these inspections sometimes take a long time, which affects the punctuality of flights. Once the passenger's certificate is found to be unqualified, the passenger will not be able to continue boarding, and the checked baggage will be found and unloaded. Because it is a stop passenger and there is no specific checked baggage list, the implementation of this work is very time-consuming.

Excessive behavior such as passengers occupying the plane or refusing to board the plane due to service problems such as flight delay.

This happens occasionally. Recently, there have been more and more serious delays caused by compensation and other issues. While safeguarding the interests of passengers, it is also infringing on the interests of passengers on subsequent flights. At the same time, it is illegal to hijack planes and other excessive acts.

Others, such as passengers getting on the plane and suddenly getting off the plane; Passengers carry too much luggage on the plane; Sudden illness of passengers, etc.

Regarding the flight delay caused by passengers, the main points that passengers should pay attention to are:

Reducing flight delays depends largely on passengers.

Please arrive at the airport in advance to go through the formalities, pay attention to the boarding time of your flight, board the plane as soon as you hear the boarding notice, and contact the staff if you need to change the itinerary.

Aircraft deployment:

In fact, this is not the reason for the delay. All other specific circumstances lead to the delay of subsequent flights, and civil aviation is counted as a plane delay. All the reasons for the delay of the plane are called plane deployment.

Generally speaking, an airplane has to carry out 6 to 10 domestic flights a day, and it takes about 10 hours to fly in the sky. In addition, when the plane is parked on the ground, it usually runs about 16 hours a day, such as picking up passengers, cleaning, loading and unloading goods, routine inspection, etc. The flight plan of each plane is arranged in advance, and there is not much room for manoeuvre. Any omission of the previous flight may trigger a chain reaction of subsequent flights, which will drag on for a longer time.

In reality, the airlines in China are small in scale, even if the three major aviation groups operate independently, the efficiency is low and the deployment space is small. Incomplete supporting facilities such as routes and airports lead to low overall flight operation efficiency. Once an accident happens, the response and deployment ability is poor. At present, airlines are actively adjusting, strengthening deployment capabilities, striving to improve flight operation efficiency and reduce flight delays.

Question 1: The flight was delayed for various reasons. Why didn't the airline prepare the plane to relieve it in time?

A: It is impossible to prepare a spare plane specially, which will greatly increase the company's operating costs. As far as the actual situation is concerned, airlines are also prepared in this regard and will leave some room when making flight plans. Every day, some planes have few flights, and some standby troops are on standby at any time to deal with the temporary deployment of emergencies. Try to shorten the flight delay.

Question 2: Airlines canceled flights and merged flights because of flight delays, which infringed on the rights and interests of passengers.

A: In fact, many times flights are cancelled or merged just to safeguard the interests of passengers. In order to solve the problem that the delay of the previous flight affects the next flight, airlines will choose to cancel or merge flights to restore the flight operation order as soon as possible.

Question 3: Why does time keep pushing and the situation keeps changing? Is it cheating?

A: At present, this is the biggest complaint of passengers about flight delay. The airline is cheating, which is actually the disadvantage of constantly providing delayed information. Each airline has a dispatch center, which comprehensively and meticulously deploys the operation of all aircraft. Once there is a problem in a certain link, such as aircraft failure and the closure of an airport, it will have an impact on the whole flight operation, and the dispatch center will make timely adjustments according to the situation. The purpose is to resume the normal operation of the flight as soon as possible, and inform the subsequent flights to make corresponding preparations. It is expected that there will be delays. However, the situation is constantly changing, and it is not ruled out that new situations will arise during the deployment process, such as further delays, which will force some plans to be changed, and will also lead to repeated delays.

The key points that passengers should pay attention to when deploying delayed flights are as follows:

In civil aviation, it is absolutely unnecessary to provide false information unless there is a need for confidentiality. Inconsistency of information before and after the occurrence is often caused by changes in specific circumstances or temporary deployment of airlines.

Flight delay summary:

Flight delay is very painful for passengers and airlines. No airline is willing to delay the flight, no airline does not try to remedy it after the delay, and no airline does not want the delay to be as short as possible. However, no airline can say that its flight will not be delayed. We never expect the punctuality rate of flights to be 100%. Passengers fly to get to their destination quickly. If there is delay, losing money is definitely not a good solution to the problem. Linking procrastination with losing money will only bring many side effects.

The key issue is how to deal with flight delays.

The first is the requirement of the right to know, and the information should be timely and transparent.

After the flight is delayed, the airline should inform the passengers as soon as possible and tell them how long the delay is expected. Timely help delayed passengers to change to other flights. At present, the information release and interpretation of the relevant civil aviation departments are really not in place, or the related services are not in place, and they are often limited to providing drinks and meals.

It should be said that most passengers have a better understanding of the operation of airlines. After the flight is delayed, the requirements are not high. They just want to know the reason and time of the flight delay. It is not their intention for passengers to ask for compensation. What measures have the airlines taken to remedy the situation? Once these basic requirements are not met, simple things often become complicated.

Secondly, the relevant supporting arrangements should be thoughtful.

Flight delays will inevitably affect the travel safety of some passengers. For example, for passengers who transfer, the staff should try their best to make proper arrangements for passengers so that they can wait with peace of mind.

Moreover, it should be handled and compensated in strict accordance with the regulations, and passengers can get it without negotiation.

Flight delays should be handled and compensated in strict accordance with regulations. At present, airlines always take a conciliatory attitude, so that passengers who make trouble are often better handled. In this case, there is no doubt that passengers' confidence in making trouble when the next flight is delayed has increased, because there is a precedent, what they did last time should not be worse than last time, and they have thought that they should do so.

After the flight is delayed, civil aviation should also take the initiative to communicate with the media, feedback the reasons for the delay to the media in time, what remedial measures have been taken and what arrangements have been made for the passengers, ensure that the media can hear both sides of the story, at least ensure that journalists do not completely follow the passengers' emotions, but convey information to the media in time, which can often turn a bad news into a good thing, and the transmission of this information will also affect ordinary people's understanding of the flight delay and eliminate many problems arising from civil aviation.
