How long should the CVR ERASE button be pushed to erase the tape?

• A. 1 second
• B. 2 seconds
• C. 1 minute
• D. 2 minutes

Answer: (B)

The CVR (Cockpit Voice Recorder) ERASE button must be held for a specified duration to ensure that the recorded data on the tape is completely erased. The correct duration is 2 seconds. This requirement is designed to avoid accidental erasure during routine checks or maintenance operations. Pushing the button for this length of time ensures that the system registers the command to erase the recordings completely, allowing for a clear understanding of the operational status and voice recordings when required. Holding it for a shorter duration, such as 1 second, may not activate the erase function effectively, leaving residual data on the tape. Similarly, longer durations like 1 minute or 2 minutes are excessive and unnecessary for this operation, as the system is programmed specifically to respond within the 2-second timeframe. Thus, knowing the correct duration is crucial for maintaining the reliability and integrity of the cockpit voice recordings.
