How do you understand an airplane circling overhead?

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.

Airplanes always circling over the airport? It's important to know what it means when traveling on a plane!

Now more and more people choose the plane as a means of transportation, although the current high-speed rail is also very convenient, the speed is also very fast, but if you want to go to some far places, the high-speed rail will not be much cheaper than the plane, and the plane will be a distance of one or two hours, the high-speed rail may have to go for more than half a day or longer. And there are some places that cannot be reached by high-speed rail temporarily, such as when we travel abroad, or there are moats such as oceans and mountains between us and the places we want to go, so if we don't want to waste time on the road, we can only choose to take a plane.

Some people often travel by plane or go on business trips, and they must be able to find a phenomenon, that is, the plane will circle over the airport when taking off and landing, sometimes just a circle, sometimes it may circle for a long time. I don't know if you have ever wondered why the plane hovers over the airport, is it an unwritten habit or a necessary operation?

In fact, circling the airport during take-off or landing is a routine operation that must be performed. One of the reasons for circling during takeoff is to climb to the specified altitude, and the flight altitude of civil aircraft is strictly regulated, and if you do not sail at the specified altitude, it is not only prone to problems such as air flow disturbance, but also makes the fuel consumption of the aircraft rise significantly. Another reason is that although the sky is vast and infinite, the plane also has to sail according to the road similar to the car, the airport takes off and lands the plane is very frequent, many routes may be occupied, and the plane takes off and circles over the airport to wait for the route to be empty, and then enter the route when the tower issues an order.

Hovering when landing is much more complicated than when taking off, not only because of waiting for the landing runway to be cleared, but also because of determining whether the wind speed, weather, field of view and other aspects are suitable for the aircraft to land, in addition to consuming excess fuel. In fact, this is not a meaningless waste, and the difference between airplanes and other means of transportation is that after a plane crash, the chances of passengers and crew escaping will become very small. If there is an excess of fuel in the aircraft when it lands, the aircraft may overweight and run off the runway, and the fuel in the aircraft will also occur**, and the chances of survival of passengers will become smaller.

Due to the particularity of the aircraft, every link related to the aircraft is very rigorous and meticulous, even when taking off and landing, you have to hover over the airport and wait for instructions, so if you plan to travel by plane, you must understand that the hovering of the plane during take-off and landing is not because of the plane or the airport, do not panic and spoil the mood of travel. In fact, airplanes are now the safest means of transportation in the world, and the reason why everyone remembers all kinds of air crashes so clearly is mostly because of the "survivor illusion", if you decide to travel by plane, then the most dangerous time on the way is when you take a car to the airport.

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.

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.

Sometimes the plane hovers in the air, for many reasons, the physical education teacher said that it is a situation, in addition to this: when the plane is descending, in order to align with the airport runway, the pilot must constantly adjust the attitude of the aircraft before landing; Sometimes, when the weather over the airport is bad and the visibility is low, the plane can only turn around and wait for the command of the air traffic control until it receives the order to allow landing. And so on, and so on, and the plane hovers in the air.

Hovering is an operation performed by an aircraft in the air, which is generally used to wait or adjust the flight altitude and speed. During flight, aircraft need to maintain a safe distance to avoid collisions with other aircraft, and also need to adjust flight attitude, altitude and speed to adapt to different meteorological conditions and flight paths. Occurring circling is one way to ensure that these conditions are met.

In most cases, planes hover because air traffic control requires permission for them to wait for landing or take-off. When an airport or air traffic control tower detects that there is heavy flight traffic, the aircraft will be asked to wait in a circle in a certain area. This area is often referred to as a hovering area, and these areas are located near airports or other areas with heavy flight traffic.

In addition, the aircraft may also hover in other situations. For example, in a special mission, an aircraft may need to maintain a stable flight altitude or speed to perform a certain mission. In the event of an emergency, the aircraft can also be closed and can choose to hover the sedan to wait for the rescue team or other support personnel to arrive at the scene.

It is worth noting that hovering can have an impact on fuel consumption. While the aircraft is circling, the engine needs to be constantly used to keep flying. This can lead to rapid fuel consumption, so crews need to consider how to maximize fuel usage while maintaining flight safety.

In flight, hovering is a relatively common maneuver. Whether it's air traffic control or other crew members, this operation needs to be deeply understood and mastered to ensure that the aircraft can fly safely in a variety of situations. <>

If the plane can't fly, why call it an airplane? When a plane flies in the sky, it hovers in the air!

Sometimes the plane hovers in the air, for many reasons, the physical education teacher said that it is a situation, in addition to this: when the plane is descending, in order to align with the airport runway, the pilot must constantly adjust the attitude of the aircraft before landing; Sometimes, when the weather over the airport is bad and the visibility is low, the plane can only turn around and wait for the command of the air traffic control until it receives the order to allow landing.
