EXCLUSIVE: “Sacrosanct Features Of Black Box”
Due to the recent crashes of aircraft around the world, passengers have however argued on the exclusive importance of the Black Box in an aircraft, as it has been a major concern and has continued to raise dust.
Although plane crashes are statistically rare, when one does happen, it’s the black box that is the key to figuring out what went wrong.
Despite the name, they’re not actually black, but bright orange, so they can be easily found. An electronic device stored at the tail of the plane that records flight information (black box). Airplanes have two of them: the Cockpit Voice Recorder (CVR), and the Flight Data Recorder (FDR).
The CVR records conversations, air traffic control and warning sounds in the cockpit from the two most recent hours of a flight. The FDR keeps track of the plane’s vital information, like speed, altitude, engine power, fuel levels, temperature and flight controls. It records up to 25 hours of data, and after that it records over existing data.
Black boxes can get damaged, but their “crash-survivable memory units,” which protect the memory cards, are practically indestructible. They’re wrapped in a thin layer of aluminum, an inch of high-temperature insulation and are covered in stainless steel or titanium.
Black boxes are built to survive acceleration up to 3,400 Gs, an hour in temperatures as high as 2,000 degrees Fahrenheit and to survive being submerged in water at a depth of not less than 20,000 feet. They have an underwater beacon that emits a pulse every second and is detectible by sonar for about 30 days.
With hundreds of thousands of flights taking off daily around the world, when it comes to the essential roles of black boxes on planes, at least you can say, “Now I get it.”
