What is the function of a Flight Data Recorder?

• A. Records flight parameters and control inputs for safety investigations and performance analysis.
• B. Records only fuel consumption data for cost analysis.
• C. Monitors cabin crew communications for HR.
• D. Logs maintenance tasks performed during flight.

Answer: (A)

The function of a Flight Data Recorder is to capture a wide set of flight parameters and control inputs over time for safety investigations and performance analysis. It collects data from many aircraft systems—things like airspeed, altitude, vertical speed, attitude, engine performance, and the positions of flight controls and autopilot modes—so investigators can recreate what happened during a flight and understand how the aircraft behaved in different phases and conditions. This information supports事故 investigations, helps verify pilot actions, and allows operators and manufacturers to study performance trends for safety improvements and training. The other options miss the broader, ongoing data collection purpose: recording only fuel data isn’t sufficient for comprehensive analysis, cabin communications are handled by the cockpit voice recorder, and maintenance tasks are tracked separately rather than by the FDR.
