Flight data recorder (FDR)

Definition

A flight data recorder (FDR) is an electronic device used in aircraft to continuously collect and store crucial flight information, such as speed, altitude, and heading, along with other operational parameters. This data is essential for accident investigation and prevention strategies, providing valuable insights into the events leading up to incidents or crashes, thereby enhancing aviation safety.

5 Must Know Facts For Your Next Test

1. The FDR records various flight parameters over time, often capturing hundreds of hours of data, which can be crucial for understanding the aircraft's performance during flight.
2. Typically designed to withstand extreme conditions, FDRs are housed in crash-survivable memory units that can endure high-impact forces, fire, and deep ocean conditions.
3. The data collected by an FDR is vital for regulatory bodies like the National Transportation Safety Board (NTSB) or the Federal Aviation Administration (FAA) during investigations.
4. FDRs have evolved from analog devices to sophisticated digital systems that can store large amounts of data more efficiently and reliably.
5. International regulations mandate the installation of flight data recorders in commercial aircraft, making them a standard safety feature worldwide.
