Cockpit Voice Recorder (CVR)

A Cockpit Voice Recorder (CVR) is a device installed in aircraft that records sounds in the cockpit, including conversations between pilots, radio communications, and ambient noises. Its primary purpose is to provide investigators with crucial audio information after an incident or accident, helping them understand what was happening in the cockpit before and during the event. The CVR typically records the last 30 minutes to an hour of audio on a continuous loop and is built to withstand extreme conditions such as fire, water, and impact, ensuring the data is preserved for safety investigations.
