What device must a technician plug into a Cockpit Voice Recorder (CVR) control head to perform an operational check?

• A. A microphone
• B. A headset
• C. An external speaker
• D. A flight data display

Answer: (B)

To perform an operational check on a Cockpit Voice Recorder (CVR) control head, a technician must plug in a headset. This is essential because the headset allows the technician to listen to the audio recordings and verify their quality, clarity, and functionality. During the operational check, it is critical to ensure that all voice communications are being captured accurately, and using a headset provides a direct audio feedback loop for this purpose. The headset can help in detecting any issues like distortion, interference, or incomplete recordings, making it a vital tool for this specific testing process. Other devices like a microphone or external speaker do not provide the same level of utility for listening purposes, as they may not create the controlled environment needed for accurate audio assessment or may not connect appropriately for the operational check. While a flight data display provides crucial flight information, it does not contribute to evaluating the audio recording capabilities of the CVR.
