The sky is divided into the troposphere and stratosphere. Both the clouds and the planes are in the stratosphere. Lightning occurs when the electrical properties between clouds are opposite. The plane is flying in the stratosphere, and the weather conditions are not good for flying during thunderstorms.
The airplane is a metal body with static electricity, and the electric charge is mostly concentrated at the tip and edge of the airplane, so the trailing edge and tip of her nose, wings, and tail are the most susceptible to repairs by the thunderbolt; However, it is difficult to predict where the lightning strike will be, and sometimes the part favored by the thunderbolt is the belly of the aircraft! Because some models are equipped with antennas in the abdomen, they become the "leads" of lightning.
The aircraft has been designed with lightning strikes in mind, so the wings and fuselage are equipped with electrostatic dischargers, which can discharge the static electricity accumulated on the surface of the aircraft into the atmosphere, so as to prevent the charge of the fuselage from attracting electricity in the clouds. But the nose of the aircraft and the material of the fuselage are different, the nose (radome) of modern aircraft is made of fiberglass, so that the weather radar wrapped in it is easy to receive and emit radar waves, will not be isolated by metal, and because of the electricity comes and goes, so the nose end of the aircraft is the most likely to provoke thunder and lightning, especially in the frequent thunderstorms in summer, the aircraft can always dodge and dodge the thunderstorm pack, because the weather radar can detect a large thunderstorm bag with abundant moisture in front of it very early. But in the case of not being able to dodge, there is only a hard break. Although it is difficult to say where the entire plane will be kissed by thunder, the nose of the precious plane has been protected by hidden weapons - metal discharge strips, a few copper wires concentrated towards the tip of the nose.
When the nose of the machine was hit by thunder! These copper wires will absorb the energy of thunder and lightning and jump up, replacing the weather radar to take the wrath of Lei Gong!
According to the ICAO report, it is not uncommon for aircraft to be struck by lightning, but there are almost no major accidents caused by lightning strikes, although it is possible for Lei Gong to make a hole in the skin of the fuselage (which will not pierce the aircraft). According to the maintenance manual of each aircraft, the aircraft has its fixed maintenance specifications after being struck by lightning (maintaining the aircraft baby is an important job of the airline) to make sure that all parts of the aircraft are in good condition!
For example, on May 14, 2006, Senator Edward Kennedy of Massachusetts was unfortunately struck by lightning during the flight on the 13th, and the electronic equipment on board failed, forcing him to change course.
-
Yes, but now airplanes are equipped with advanced lightning protection equipment.
-
Of course, as long as the positive and negative electrodes are conducted, they will definitely be split, but the probability of being hit by lightning is relatively low. It's not because of what the friend said above. The main thing is that people use passive measures to avoid lightning, that is, the best way to avoid the plane from being hit by lightning is not to fly over thunderstorm clouds.
It's easy, right? Each airport has a dedicated weather team, and the radar on the aircraft can be used as a weather radar. If you encounter a thundercloud in the air, the plane will fly high and fly above the thundercloud. If you encounter thunderstorm clouds when you want to land, you will consider transitioning.
If there are thunderclouds during take-off, you will be given a free lunch at the airport and you will hear a radio message telling you that the plane will not be able to take off for a while, so don't leave the airport too far.

What happens when you encounter lightning while flying?
-
A lightning strike on an airplane is not a big deal for flight:
On average, an aircraft may be struck by lightning once every 10,000 flight hours, but since most of the casing is a conductor, these powerful currents will only flow smoothly through the fuselage or wing skin, leaving small ablation holes or gaps, which are not a major problem for the aircraft to fly. Modern new aircraft have well-sealed structural fuel tanks that prevent sparks from detonating, and lightning does not enter the conductor and injure the passengers inside. However, the magnetic field formed by the strong current will have a great impact on the system.
Measures to reduce aircraft from lightning strikes:
In order to reduce the chance and harm of aircraft being struck by lightning, there are two ways to do this:
1. Adopt many lightning rods protruding from the fuselage or wings to discharge.
2. Use a good conductor to connect or cover the part of the bad conductor of the casing to channel the current and reduce the damage.
-
No, because the shell of the plane has a conductive device, a news report two days ago just reported that a plane in the United States was struck by lightning, and it was very detailed.
The fuselage of the airliner is mostly made of aluminum, which protects against lightning of up to 30 million volts, so that when struck by lightning, the current does not accumulate at the edge of the aircraft, but conducts along the smooth aluminum shell, and the current does not penetrate the fuselage. This could also explain why many planes were struck by lightning and came out unharmed. In fact, it was the lightning that was conducted along the upper part of the fuselage to the ground.
In addition, airliners' fuel tanks also need to be rigorously tested to ensure that they do not produce dangerous sparks after being struck by lightning. All electronic components and navigation equipment on board the aircraft also require special handling.
-
Not necessarily, it depends on the extent of the damage. If you just split the plane in half, it's over. If a part of the plane is destroyed, even if it is the engine, a skilled pilot may be able to make a safe landing.
-
Beyond your imagination, what happens when a plane is struck by lightning?
-
No, the current jet planes fly at an altitude of 9146 meters or 10668 meters, this altitude will not appear weather phenomena, it is the stratosphere, jet business jets, commercial airliners, civil airliners are flying in the stratosphere, *** encounter thunderstorm clouds to fly around, because the air above 8000 meters is thin *** can not climb, can only fly around, because *** belongs to a typical low-altitude aircraft so can only fly around, while other jet aircraft can fly to 9146 meters, 10668 meters, 11000 meters, 12,000 meters, 12,600 meters, civil airliners, commercial airliners, business jets, domestic routes are at 9,146 meters, domestic long-distance routes are at 10,668 meters, international routes are at 12,000 meters or 12,600 meters, the flight altitude of general aircraft is at 9,146 meters or 10,668 meters 15,000 meters, the height of this interval is the stratosphere, is flying above the clouds, the general cumulonimbus clouds are from 600 meters to 9,000 meters, if there are thunderstorms and charged rain and fog weather over the airport, the plane should hover in the stratosphere and wait for the notice, if it has not improved, it can only go to the airport with good weather to divert or return home, can not descend because there is low-altitude wind shear under the cumulonimbus cloud, lightning strike, charged rain fog, low visibility, the plane must fly above the cumulonimbus cloud, the height of the cumulonimbus cloud top is 9000 meters, so the aircraft flies above 9000 meters, that is, the flight above the cumulonimbus cloud will not be struck by lightning, the cloud is distributed in the troposphere below 9000 meters, the aircraft flies at 9000 meters or 10668 meters, Therefore, the aircraft will not be struck by lightning.
-
No, I haven't heard of planes being struck by lightning. Rushing into a thundercloud is another matter.
-
Yes, but the people in there will be fine, just like a car, as long as you don't touch the metal parts.
-
Under normal circumstances, the altitude of the aircraft is in the stratosphere of the atmosphere and does not pose a danger to the aircraft.
-
Although it will.
There will be nothing going on inside.
-
Yes, but the people inside won't be fine, just like cars.
-
When an airplane is struck by lightning, the lightning current is very strong, and it only flows smoothly through the skin of the fuselage and wings. Therefore, only very small cautery holes or very small notches will be left on the fuselage, which will have extremely little impact on the normal flight of the aircraft.
In addition, after countless flights, intelligent humans have found patterns and devised a specific program that pilots can use to roughly perceive the thunderstorm area through weather radar, surveying the environment, etc.
-
The captain will transform into Ultraman and carry the plane and shuttle through the lightning!
-
First of all, the cockpit and shell of the aircraft are insulated, and there is no danger of electric shock in the event of a lightning strike. The wings of the airplane have a number of small sticks called discharge brushes, which release the charged charges gathered by the fuselage into the air, minimizing damage in the event of lightning. However, due to the high energy of lightning, extreme conditions can directly burn the fuselage structure, interfere with navigation electronics, or cause a fire.
Modern aircraft are equipped with weather radars on the head, which can observe the cloud conditions within a range of 100 kilometers, and will change course to avoid dense cumulonimbus clouds to minimize the risk of being struck by lightning.

Then put your hands together and say, "Superman, you're there." , quickly appeared.
-
Flying is now the most efficient way to travel long distances, and flight safety has always been a top concern. So how much of an impact does the safety of the Blitz aircraft have? Let's take a look today.
-
This is not necessarily, the metal casing of the aircraft applies high voltage, just surface equipotential. Internally, it is a small induction. There are 2 cases, one, lightning will not discharge the aircraft at all because the aircraft is at high altitude and is not grounded.
Second, even if it is hit, it is not a long-term continuous discharge, and the loss should be avoided. This situation has basically not been reported, and there have been accidents. It's normal to actually encounter this situation.
The person is seated in the car, the car is connected to the high voltage, and nothing happens. Equipotential is the reason why birds, 2 feet stand on a wire, and are not clicked.
-
Generally speaking, there is no big problem, the aircraft skin made of aviation aluminum will evenly disperse the electricity, so that the entire fuselage can withstand the electric shock, and a part of the electricity will be released from the discharge brush at the end of the wing. However, the carbon fiber fuselage used in modern aircraft cannot do this, so a very thin layer of aluminum wire mesh is laid under the coating to achieve the effect of aluminum.
-
It's not a big problem, because all the planes are resistant to lightning strikes.
-
Because most (90%) of the lightning that strikes the aircraft is triggered by the aircraft, and the remaining 10% (the lightning that starts naturally) also plays a key role in the distortion of the electric field caused by the aircraft itself, which will make the discharge more producible, and the "pilot" that starts from the airframe will develop towards the "pilot" that starts in the cloud, which in turn leads to the final lightning strike.
While airplanes can be struck by lightning, most of them do not lead to catastrophic consequences. "This is mainly due to the fact that the current commercial aircraft shell is made of metal material, which has a good shielding effect, and the personnel and equipment inside the aircraft are relatively safe. But that doesn't mean the plane didn't suffer any damage when it was struck by lightning.
The aircraft is not a fully shielded "Faraday cage", there are many openings in it, some areas are non-metallic (such as the radome in the front of the aircraft), and some antennas are exposed, and the intense electromagnetic radiation from lightning can still cause serious damage. In addition, strong lightning currents can also cause the metal to melt.
-
Yes, every functioning aircraft is struck by lightning almost every year.
The chance of an aircraft being struck by lightning has a lot to do with the season and the route it flies. The majority (90%) of the lightning that strikes the aircraft is triggered by the aircraft, and the remaining 10% (the lightning that starts naturally) also plays a key role in the distortion of the electric field caused by the aircraft itself, which will make the discharge more producible, and the "pilot" that starts from the airframe will develop towards the "pilot" that starts in the cloud, which in turn leads to the final lightning strike.
-
Airplanes can be struck by lightning in the air.
1. The airplane is a metal body with static electricity, the metal on its surface is charged due to electrostatic induction and friction electricity, when the electric field strength reaches about 418V m, atmospheric discharge (lightning) occurs, and thunder and lightning are mostly concentrated at the tip and edge of the aircraft, so the trailing edge and tip of her nose, wings and tail are the most vulnerable to lightning strikes.
2. Due to the needs of the mission, combat aircraft will often fly in the troposphere and bad weather, and these places are often struck by lightning when the plane flies over.
-
In thunderstorms, the aircraft may be struck by lightning at any time during the flight, and the aircraft can fly safely on sunny days.
-
There are cases of machines being struck by lightning, but not many.
The reason is that lightning goes in the direction of the electrostatic potential difference. The aircraft is designed with an electrostatic discharge device in mind to avoid the accumulation of static electricity in the fuselage. As a result, lightning generally does not strike aircraft directly.
However, it is impossible to predict the direction of lightning in the air, and unfortunately the aircraft will still be damaged if it happens to be in the middle of a lightning bolt or too close to the lightning. Therefore, pilots should still avoid it. Large aircraft are equipped with thunderstorm cloud detection radars, and small aircraft rely on the ground to navigate to avoid possible dangers.
-
Generally speaking, civil aircraft are in the stratosphere when flying, where the environment is relatively stable, so the impact of lightning is not large, but for combat aircraft, because of the needs of the mission, they will often fly in the troposphere, so many bad weather, including lightning, has a considerable impact on the aircraft, in World War II, there were combat aircraft crashed due to lightning and other factors, but modern aircraft also have corresponding protective measures, so the impact is greatly reduced, but also can not ignore the weather factors, Therefore, aircraft should still choose to avoid bad weather when performing ordinary tasks.
