A flight data recorder is a critical component in modern aviation, primarily serving the purpose of recording various parameters of the flight as it occurs. This device collects and retains data from multiple sensors located throughout the aircraft, capturing important information such as altitude, airspeed, vertical acceleration, and heading.

In the event of an incident or accident, this recorded data becomes invaluable for investigators trying to understand the factors leading to the event. By analyzing the information captured by the flight data recorder, experts can piece together the sequence of events, identify any anomalies in aircraft performance, and determine if any procedural errors took place. Thus, the primary role of a flight data recorder is to support accident investigations, helping ensure safety improvements in future operations based on the findings.
