A cockpit voice recorder is like a special tape recorder that is placed in the cockpit of an airplane. It's a very important tool that helps investigators figure out what happened in case something goes wrong during a flight.
The recorder takes in all of the sounds that the pilots can hear in the cockpit, like their voices, the sounds of the engines, alarms, and other things that happen during a flight. It's like when you make a video with your parents and you can hear everyone talking and laughing.
So if something goes wrong during a flight, investigators can use this recorder to listen to what the pilots were saying and what was happening at the time. This can help them figure out if the pilots made any mistakes or if something went wrong with the plane itself.
It's really important that the cockpit voice recorder is always working and well maintained because it can provide crucial information that can help make flying safer for everyone.
