Air traffic control reasons?

There are two kinds of delays before the plane takes off, one is due to airlines and the other is due to air traffic control. Airline reasons include aircraft turnover, delayed crew and aircraft maintenance. In short, the plane or crew didn't arrive at the airport on time/get ready for takeoff. Air traffic control means that the plane has all other takeoff conditions, but the tower won't let it. There are many reasons for not letting go. There are three kinds of weather: departure airport weather, destination weather and, most importantly, airline weather. Bad weather (heavy rain, fog, thunder and lightning, strong wind, etc.). ) Not suitable for take-off and landing and flying. One of them can't fly in bad weather. China's airspace is completely under the air force's control. The air force will use 20% of it for civil aviation (it can be recovered at any time). In this 20% space, some routes have been set up. There are requirements for the front, rear, left and right distances of aircraft on the route. There are too many planes on the same route to allow new planes to fly in, otherwise there will be safety problems. Military activities. As mentioned above, the air force gave 20% of the airspace to civil aviation. The air force needs it, and civil aviation needs to make way. Typical is a military exercise. Then a no-fly zone (usually 300-500 kilometers) will be drawn nearby, and all planes will bypass and the route needs to be adjusted. Runway problem. The airport runway may need maintenance, or something happens on the runway (such as a large number of birds), then the runway will be temporarily closed. With fewer runways, the take-off and landing capacity will be reduced, but flights are arranged according to normal conditions, so extra queuing time is needed. Air traffic controllers also have little to do (except Li Gang on the plane), so they can only wait in line patiently. Queueing is based on closing the hatch (that is, the plane can push out, taxi and then take off). Planes with closed doors can line up at the tower, and they can't line up until they are closed. So airlines don't really want to leave passengers in the cabin when they encounter air traffic control. Because if you don't lock it in the cabin, you will never take off. Of course, not all delays are air traffic control, nor are they claimed to be air traffic control.

What should I do because of the air traffic control flight delay?

The delay caused by air traffic control is irreparable. At present, only the airlines with scheduled flights can compensate for the delay. Moreover, new regulations have been issued recently, and it has been determined that the delay caused by the weather cannot be compensated. So is air traffic control. Delays caused by non-airline reasons will not be compensated. Of course, it is your ability to get compensation through other channels.

Why does Shanghai Hongqiao Airport control air traffic every day?

Because we have to avoid those military planes

Why is there always air traffic control recently?

There are many reasons for the delay, such as weather, plane failure, passengers being late, etc.

But air traffic control sounds mysterious. Passengers do not know what air traffic control is. There are many reasons for air traffic control, not necessarily the reasons of air traffic control units.

The weather in all parts of the country can't be bad at the same time, but regional bad weather often happens, and an airplane doesn't just fly once a day, so the delay in the first paragraph will affect the normal flight in the future. It also has something to do with the World Expo. Planes all over the world have gone to East China, so it is necessary to control the flow to some extent, otherwise the flight safety will be difficult to guarantee.

How does air traffic control affect the punctuality rate of aircraft

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 a flight: 1. Flow control: In recent years, China's civil aviation has developed rapidly and the number of flights has surged. However, the corresponding ground facilities, navigation equipment and service support have developed slowly, and the route structure is unreasonable, which cannot adapt to the rapid development of the current civil aviation industry. Especially for reasons such as ensuring national defense security, China has imposed strict restrictions on airspace, and there are many air restricted areas. The military is responsible for organizing the implementation of national flight control, and the adjustable redundancy in civil aviation is very small. Recently, the situation has improved, and some air routes have also achieved radar control, effectively alleviating the phenomenon of tin pushing, but the overall progress is not great. 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.

Interpretation of common situations: Question 1: After the passengers on the plane, the doors are closed and everything is 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: The plane is ready, taxi for a while and then stop. 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 wait for a long time because of the flow control, and then say that you can't leave, you have 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: Normal flow control has a predetermined time, and the crew will decide whether passengers wait after boarding or in the terminal according to the situation, but as mentioned above, sometimes air control is not planned in advance. ......

There is a term in aviation terminology called air traffic control. What is the reason?

Air traffic control, to put it bluntly, is that there is a traffic jam in the air that needs the police to adjust.

The air traffic controller plays the role of a policeman. Air traffic control means that there are multiple take-off and landing flights at the same time. In order not to affect the on-time take-off and landing tasks of subsequent flights, it is necessary to control flights that are about to land but in the air and flights that are about to take off but have not yet taken off.

The Civil Aviation Law of People's Republic of China (PRC) is interpreted as:

According to Order No.38 of the Civil Aviation Administration of China in February 1994+0, the rule was abolished by Order No.86 of the Civil Aviation Administration of China on July 5, 0999), the following is an excerpt from the general provisions of Chapter II of the rule:

For the contents of the current standards, please refer to the Civil Aviation Law of People's Republic of China (PRC).

Article 7 Air traffic in civil aviation controlled airspace is divided into tower control area, approach control area and regional control area.

Tower control area generally includes landing route, instrument approach procedure route, space below the first waiting floor and airport maneuver area. Its specific scope is stipulated in the Rules for the Use of Airports.

The approach control area is the connecting part between the tower control area and the regional control area, and it is the space in the airport control area except the tower control area, and its specific scope is stipulated by the airport use rules.

Regional control zones refer to several high-altitude control zones above 7000m (inclusive) and several low-altitude control zones below 7000m (exclusive). The specific scope of each regional control zone shall be stipulated by the Civil Aviation Administration.

Article 8 The airport control area is usually a space centered on the airport reference point, with a horizontal radius of 50 kilometers and a vertical height below 7000 meters. Airports with air corridors or entry and exit points also include parts of air corridors or entry and exit points. Its specific scope is stipulated in the Rules for the Use of Airports.

Article 9 The height between 6000 meters (excluding) and 7000 meters (excluding) is the conversion space between high and low altitude control zones, which belongs to the control scope of low altitude control zones. Before the high-altitude control room instructs the aircraft to enter the conversion space, it must obtain the permission of the relevant low-altitude control room; Before using the conversion space, the low-altitude control room shall notify the relevant high-altitude control room.

Section 2 Control Unit

Article 10 The control of the air traffic control area shall be implemented by the tower air traffic control room (hereinafter referred to as the tower control room), air traffic service report room (hereinafter referred to as the report room), approach air traffic control room (hereinafter referred to as the approach control room) and regional air traffic control room (hereinafter referred to as the regional control room). The dispatching rooms of CAAC and CAAC are respectively responsible for.

Supervise, inspect and coordinate the flight organization and implementation within the national and local administrative agencies.

The tower control room should be equipped with control tower and take-off line tower, and the airport with busy flights should also be equipped with ground control.

The approach control room can be set as an independent unit or combined with the tower control room according to the busy flight.

The regional control room has high-altitude and low-altitude control rooms, which can also be merged into one control room according to the busy flight situation.

Article 11 The duty of the control unit is to provide air traffic control, flight information and warning services for aircraft within the control area.

(1) Tower control room: responsible for the control of the start-up, taxiing, take-off, landing and related maneuvers of the aircraft in the tower control area.

The control room of the tower with busy flight shall set up airport automatic information service to provide flight information such as aircraft take-off and landing. The tower control room authorized to be responsible for approach and partial area control shall also provide approach and partial area control.

(2) Report room: responsible for listening to the flight forecast of aircraft entering and leaving the airport, declaring the flight plan, handling the departure procedures of aircraft, and informing the relevant control rooms and units of the flight forecast and dynamics. Grasp and report the opening and closing of this airport.

(3) Approach control room: responsible for controlling the entry and exit of aircraft into one or several airports.

(4) Regional control room: responsible for the flight control of aircraft in this controlled area. The low-altitude area control room also accepts the flight application of general aviation in this control area and is responsible for the control work. Accepting flight applications for the take-off and landing of non-civil airports within the control area, the routes are guaranteed by the civil aviation department, and they are responsible for the control work and inform the relevant control rooms of flight forecasts and dynamics.

(5) Dispatching Room of the Regional Administration of Civil Aviation (hereinafter referred to as Dispatching Room): responsible for supervising and inspecting the flights within the local administration, coordinating the organization and implementation of flights between control rooms and between control and airline navigation departments within the local administration, and controlling the flights within the local administration. ......

I missed the next flight because of air traffic control. Is this because of the airline?

No, nobody is in charge.

The controller won't let you burn oil there for no reason, all for safety.

Is there any compensation for seven or eight hours delay due to air traffic control?

Of course not. . .

There will be traffic police road control when taking the bus, so it is naturally easier for planes with stricter requirements to be delayed. This is not the airline's own problem, so of course they will not compensate.

How to know in advance whether there is air traffic control?

Air traffic control is a temporary measure. Because the flight flow is too large, in order to ensure the safety of the aircraft, the flow control will be adopted (that is, the aircraft will not be allowed to go), and the pilot will push back and taxi to take off after the flow is smaller.
