What is a Flight Data Recorder (FDR)?

A Flight Data Recorder (FDR) is a device that plays a crucial role in aviation safety by recording various flight parameters. It captures a range of critical flight data, including altitude, speed, heading, and flight control positions, among other variables. This information is invaluable for analysis in the event of an incident or accident, as it helps investigators understand what occurred during the flight. The recorded data can be used to improve safety measures and enhance operational procedures, thereby contributing to safer air travel.

In the context of this question, choosing the definition of the FDR as a device that records critical flight data for analysis accurately reflects its purpose and importance in the aviation industry. The other options do not pertain to the primary function of an FDR, reinforcing why they are not suitable descriptions of the device.
