Hey there kiddo! Let me explain what ETOPS is.
You know how airplanes fly very, very high in the sky and can go to so many different places all over the world? Well, sometimes those flights can be really, really long. To make sure that the airplanes are safe when they fly for a long time over water, they have something called ETOPS.
ETOPS stands for "Extended-range Twin-engine Operations." It means that when an airplane has two engines and it's going to fly over a big stretch of water, like the Atlantic Ocean or Pacific Ocean, it needs to follow certain rules to make sure it can fly safely.
The rules say that the airplane needs to be able to fly with only one engine working, just in case something goes wrong with the other engine. That way, the plane can still fly safely to a nearby airport and land without any problems.
It's important for airlines to follow these ETOPS rules so that passengers feel safe and comfortable when flying long distances over water. So the next time you take a long flight, you can be confident that ETOPS is helping to keep you safe in the sky!
