Dear MEL Topic Readers,
What you need to know about black boxes?
The black boxes were recovered from the crash site of China Eastern Airlines MU5735 that fell and killed all 132 people on board on March 21. What is the black box in aviation? It is a flight recorder equipped in an aircraft to facilitate the investigation of an accident or incident. There are two types of devices, one is the flight data recorder that keeps flight information, such as altitude, airspeed, heading, and engine thrust. This provides the status of the aircraft for the last 25 hours. The other is the cockpit voice recorder, which records the sounds and voices in the cockpit for the last two hours. By analyzing the information from these recorders, investigators can identify the cause and situation of the accident or incident. Despite their nickname, the black boxes are painted bright orange to be recovered easily. These boxes are made to be waterproof, fireproof, shockproof, and heat and collision resistant to survive a crash. They are placed in the tail of the aircraft for higher survivability. Once retrieved, the data is decoded and analyzed, which could take days, weeks, or even months depending on the condition of the data. It is regretful that all aircraft need to be equipped with such a device but it seems necessary to identify the cause of an accident or incident for safer air travel.
Enjoy reading the article and learn about aircraft’s orange boxes which are called black boxes.
