Lightning strikes are an everyday occurrence on planet Earth: on average, lightning strikes occur 100 times every second throughout the world. Even though approximately 80% of those strikes are intra-cloud or cloud-to-cloud, i.e. lightning within the same cloud or between different clouds, they can still pose a risk to airborne objects, such as aircraft. That is why aircraft lightning protection is critical.
It doesn’t matter if the aircraft is on the ground or in the air. Lightning typically strikes through one of four external places:
A combination of lightning protection systems make aircraft very well, though not completely protected from lightning.
The Main protection systems include:
Why don’t most people know when lightning strikes their plane while in the air?
The way an aircraft tries to dissipate step leaders is through something called a “static wick“. A static wick is a piece of metal connected electrically to the frame of the aircraft, with spikes or needles on the end.
It is housed in a fiberglass rod to insulate it from the airplane. Because the spikes concentrate the electric charge around them, and they are connected to the airframe, they allow the airplane to dissipate any static electricity it may build up out into the air.
If lightning does strike the plane, the electricity will go through the dissipater and not through the airplane using the same principle as the LEC Dissipation Array System.
Lightning poses a serious threat to aircraft, and they must be protected.
