What is the CVR's audio storage duration?

• A. 15 minutes
• B. 30 minutes
• C. 45 minutes
• D. 60 minutes

Answer: (B)

The main idea here is how long a CVR keeps cockpit audio available after recording begins. A CVR uses a circular memory that continuously records, so it always contains the most recent material. For most transport-category aircraft, including the CRJ-550, the system is designed to retain the last 30 minutes of cockpit audio. Once that 30-minute window fills, the oldest audio is overwritten as new audio is recorded. This 30-minute duration is the standard minimum required by aviation regulations, which is why it’s the correct choice. Some aircraft can be equipped with longer recording times, but the typical and tested figure for this aircraft is 30 minutes.
