•The main purpose of the CVR unsurprisingly, to recordsounds that occur within the cockpit
•CVR communicate between the crew and ground control and other aircraft
Cockpit Voice Recorders:

The Positions Of The Four Microphones:
• Pilot's headset
• Co-pilot's headset
• Headset of a third crew member (if there is a third crew member)
• Near the center of the cockpit, where it can pick up audio

•visualise how a plane was handling shortly before a crash.
•To help investigators find how crash the aircraft
•able to operate between -55° to +70°C and it can carries a minimum 25 hours of flight data.
•The device is activated as soon as the recorder comes into contact with water to it known as an Underwater Locator Beacon (ULB
