recorders per aircraft

Flight recorders, commonly called black boxes, are actually painted bright orange to make them easier to locate in wreckage.

شرح

Each aircraft carries two flight recorders: the Flight Data Recorder (FDR), which logs thousands of parameters including speed, altitude, and control positions, and the Cockpit Voice Recorder (CVR), which captures audio from cockpit microphones. Both are built to withstand extreme impact forces, temperatures up to 1,100 degrees Celsius, and submersion in water for 30 days. They emit an underwater locator beacon for up to 90 days.
