What is the function of the flight data recorder (FDR)?

• A. To control in-flight entertainment systems
• B. To record flight parameters and aid in investigations
• C. To transmit real-time data to air traffic control
• D. To provide weather updates to the cockpit

Answer: (B)

The function of the flight data recorder (FDR) is primarily to record various flight parameters, including speed, altitude, heading, and other critical data from the aircraft's operation. This data is crucial for aiding investigations following an incident or accident, allowing investigators to analyze the circumstances leading up to an event and understand what might have gone wrong. The insights gained from FDR recordings can help enhance safety measures and improve future aircraft operation protocols. In contrast, controlling in-flight entertainment systems is not a function of the FDR, as it is dedicated solely to data collection relevant to flight safety. Additionally, while there are systems in place for transmitting real-time data to air traffic control, this is typically handled by different equipment, such as the transponder or ADS-B systems, rather than the FDR. Lastly, providing weather updates to the cockpit is managed through other avionics and communication systems, not through the flight data recorder, which focuses on recording flight operation data rather than relaying current weather conditions.
