A lightning strike on a plane might sound terrifying, but usually, it has no serious consequences. Aircraft are specifically engineered to handle these electrical discharges.
How Aircraft Are Protected from Lightning
According to the reference, planes are designed to withstand lightning strikes, both in flight and on the ground. The key to this protection is a concept called the Faraday cage. This cage is essentially a conductive shell that surrounds the cabin, diverting the electrical current safely around the passengers and sensitive equipment.
Here's a breakdown of how it works:
- Conductive Skin: The outer skin of the aircraft, usually made of aluminum, is an excellent conductor of electricity.
- Path of Least Resistance: When lightning strikes, the electricity travels through the skin of the plane and then exits through other parts like the wing tips or tail.
- Faraday Cage Effect: The conductive skin creates a Faraday cage, which shields the interior from the electric field, keeping passengers and electronics safe.
What Might Passengers Experience During a Strike?
While passengers are protected, they might still notice a few things when the plane is hit by lightning:
- A Bright Flash: A noticeable flash of light will likely be seen outside the window.
- A Loud Bang: A loud sound, similar to a clap of thunder, might be heard.
- Possible Minor Flicker of Lights: In rare cases, there might be a brief flicker of the interior lights.
Aircraft Design Features and Safety
A lot of engineering goes into making sure aircraft can withstand a lightning strike:
- Static Wicks: Small rods located on the wings and tail that help to dissipate static electricity, reducing the risk of lightning strikes.
- Bonding: All components of the aircraft are electrically bonded together, which ensures a safe path for the electrical current.
- Testing: Aircraft undergo rigorous testing to ensure they can withstand multiple lightning strikes without damage.
Why Planes Are Safe in a Lightning Storm
The most important thing to understand is that aircraft are designed to handle lightning strikes. The Faraday cage effect and other engineering features effectively keep passengers safe. As stated in the provided reference, usually has no serious consequences.
