How many minutes of flight can the Cockpit Voice Recorder capture?

The Cockpit Voice Recorder (CVR) is designed to enhance flight safety by capturing audio from the cockpit, including communications with air traffic control and conversations among the flight crew. The recording duration is crucial because it determines how much data can be retrieved after an incident for investigation.

The correct duration for the CVR on the CRJ550 is 120 minutes. This duration allows for a comprehensive capture of cockpit audio, covering a significant portion of a flight. The extended recording time is beneficial in scenarios where the circumstances leading up to an event might not be fully captured in shorter recordings, providing investigators with a better context of the events during the flight.

Some other options provide shorter recording times, which, while still relevant in some technical contexts, do not meet the specific capabilities of this aircraft's systems. The 120-minute specification aligns with industry standards for flight recorders aimed at improving safety and enhancing the investigatory process.
