Aircraft Black Box
Black Box is an indestructible orange colored recording device placed in aircraft which would be the only evidence to establish why a plane crash or how the aircraft met with the accident. Aviation experts normally called Black boxes as electronic flight data recorders. Their main process is to record and keep tracking on-flight data information such as altitude (height from earth surface), stability of the aircraft and speed as well as pilot conversation took place in the cockpit. Multiple functions would be carried out on-flight with multiple devices all information will be easily transmitted to the black box. It is placed on the tail of the aircraft for safe precautions.
Black box are not black in color. It is bright orange in order it would be more easily visible in wreckage.
Black box design
For safety purpose and protect the secondary components that stores information its covered with in a thin layer aluminium and 1-inch layer of high-temperature insulation, and over that shielded in a corrosion-resistant titanium or stainless steel shell. Strengthens it to withstand shocks during flight crash or fall from high altitude and went deep inside the sea.
Two separate box in Black box
Clearly there are two black boxes present in an aircraft:
- Flight Data Recorder stores the information about flight control include direction, altitude and engine performance includes speed and turbulence etc.
- Cockpit voice Recorder record the background sound on the aircraft in cockpit cabin, engine and voice conversation between the crew and control station (ATC Air traffic control) to predict the performance of the aircraft before crash or accident.
If any airplane accident happens investigators immediately begin searching for the aircraft’s black boxes.
