Cockpit voice recorders must be continuously recording from the time:

• A. The aircraft takes off
• B. Electrical power is first provided to the recorder before the flight to the time at which electrical power is removed from the recorder after the flight
• C. The cockpit door is closed for takeoff
• D. All flight operations are completed

Answer: (B)

The requirement for cockpit voice recorders (CVRs) to continuously record is established to ensure that pertinent audio data is captured throughout the flight, including critical phases such as takeoff, flight, and landing. The correct answer indicates that the CVR must start recording from the point that electrical power is provided to the recorder, before the flight begins, and must continue until the electrical power is removed after the flight is completed. This is particularly important because it allows for a comprehensive record that can be reviewed in the event of an incident or accident, capturing communications and ambient sounds that could provide context for the flight timeline and operational decisions made by the flight crew. Continuous recording throughout this period ensures that all relevant information is available for analysis retrospectively. The other options, while they mention relevant phases of flight where recording is important, do not encompass the entire requirement: they imply that recording might only start or end during specific flight operations rather than accounting for the full operational timeline from power-on to power-off.
