Why does lightning not affect planes in flight?

According to world statistics, on average, every 3,000 flight hours, each plane will be struck by lightning once. Lightning usually strikes planes with engines located at the rear (this type is increasingly rare). However, if struck by lightning in the air, the lightning will not affect the plane while in flight.

Due to its special structure, lightning does not affect the operation of the aircraft.

Lightning does not affect planes in flight.

According to a spokesperson around the world, it is normal for planes to be struck by lightning while flying in the air. But how they can survive a powerful electric shock of billions of joules, equivalent to a quarter of a ton of TNT, is something that many people find puzzling.

"The outer shell of the cabin and interior of an aircraft is designed to conduct electricity but also acts to isolate the current from the crew, passengers and many other electronic devices located inside," said Chris Hammond, member of the British Airline Pilots Association (Balpa).

Lightning bolts produce very powerful electric currents.

At the same time, Mr. Chris Hammond also added: "Inside the aircraft shell there is a metal mesh. This is a fine steel mesh, which prevents external currents from going deep inside and makes them move in the opposite direction."

In addition, the fuselage is designed with many additional shielding layers to protect the vehicle from the risk of electrical short circuits caused by external impacts. All parts of the aircraft are carefully inspected before being put into operation.

Things to note when flying

Passengers who have purchased domestic flight tickets need to prepare the following documents: Identity card, citizen identification card; Identification card, certification of the armed forces. For international flights, passengers need to prepare: Passport, visa and documents required by the destination country.

At the same time, passengers must be present at the boarding gate about 20 - 30 minutes to board the plane. This is also the time for staff to check and notify passengers who are not present at the boarding gate. The boarding gate will usually be announced to you after check-in.

When flying, passengers should pay attention to be present early at the airport and prepare all documents.

People with a history of sinusitis are easily affected by changes in airplane pressure, especially when the plane takes off and lands. Therefore, passengers should use nasal spray 2 hours before takeoff. Also, always carry the medicine with you, in case you need to use it.

The pressure on the plane will saturate the oxygen in the air. The humidity in the cabin will drop, causing bronchial dryness, which is the main cause of asthma attacks when flying. Therefore, you should do some light exercise before take-off, maybe walk around the airport.
