Airport Fire and Rescue Operations – Aircraft, Map, and Firefighting Techniques Practice Test

Preserving data-recording devices that document the flight and cockpit communications is essential in evidence handling. The Flight Data Recorder and Cockpit Voice Recorder provide objective, time-stamped information about aircraft performance, control inputs, system statuses, and crew conversations, allowing investigators to reconstruct the sequence of events and identify contributing factors. These recorders are designed to withstand crashes and are a primary, high-priority source of evidence, so securing them early helps prevent data loss or tampering. Other items like fire extinguishers, seat cushions, or window shades may be useful for clues, but they do not offer the comprehensive, verifiable record that the flight data and cockpit voice recorders provide. Therefore, the item to preserve is the Flight Data Recorder/Black Box.
