How to take data from black box

How to retrieve data from the black box. The series of black boxes, the Cockpit Voice Recorder (CVR) of the Sukhoi Superjet 100 aircraft has been found. The next job that is taking the information contained in black box.

Black box found in the Sukhoi SSJ 100 completely black due to expire. Despite called black box, the flight data recorder is usually painted orange.

Striking colors plus a line of reflective tape on the body to facilitate the search for black boxes. This design is useful when the water ends up in a plane crash.

There are two possible names from the black box. Some people believe because at the beginning of the making of this box is black. While the other refers to the color of post-fire charred after roasting in an accident.

After finding the black boxes, the investigation team will bring the tape to the lab. They will download the data from the recorder to recreate the accident. This process can take up to months to be completed weekly.

In the United States, the manufacturer gives the black box of the National Transportation Safety Board (NTSB) systems and software to perform a full analysis of the data stored.

If later on Flight Data Recorder (FDR) was found, investigators can play the material on a tape recorder by connecting it to the reader system. In the solid-state recorders, investigators can extract the data in just minutes.

Very often, the recorder was found in the ruins of the dent and fire conditions. In this case, memory boards must be removed, cleaned, and new memory interface cable will be installed.

Memory will be connected with a recorder that can work. This recorder has a special software for easy retrieval of data without the possibility overwrite the data in it.

According Howstuffworks.com, a team of experts are usually involved to interpret the data stored in the Cockpit Voice Recorder. This group generally consists of airline representatives, representatives of aircraft manufacturers, transportation security experts, investigators and air safety.

These investigators Council will interpret the conversations and sounds recorded during 30 minutes in the CVR. This process can take a very long time.

FDR and Cockpit Voice Recorder is duet invaluable tool in the investigation of aircraft accidents. Both devices are sometimes the only survivor in a plane crash. In the case of Sukhoi SSJ 100, where Flight Data Recorder was still in the search.

These devices become an important clue to unravel the cause of the accident without any other way. Along with the development of technology, the black box still plays a major role in accident investigation.

How it works Black Box Plane

How it works Black Box in plane. His name is a black box, but do not imagine that a black box as the name suggests. The color is actually bright, orange. When the plane crash, black boxes became the most wanted thing to find out the cause of woe.

Similarly, when the Sukhoi Superjet 100 aircraft fateful end. Search for black box was a priority in addition to the evacuation of victims.

The investigation will lead to the data recorded on the Flight Data Recorder (FDR) and Cockpit Voice Recorder (CVR), known as designation of this black box. This box contains a conversation in the cockpit voice data.

How it works Black Box in plane?

Magnetic tape
According to the document L-3 Communications, as the developer of the Wright Brothers first airplane also pioneered the use of the device to record the rotation of the propeller.

World War II expanded the use of flight recorders. Since then, the black box recording media have been developed to record more information about the aircraft.

Although many of the black boxes in use today use a  magnetic tape, the tool first launched around the 1960s. The airline switched to solid memory board in the 1990s.

Type of magnetic tape cassette recorder works like a popular tool used. Mylar tape rolled electromagnetic head and was left with data on the tape.

Now the manufacturer no longer makes the black box with a magnetic tape recorder. The plane has been transformed into drive technology (solid-state).

Solid-State Drive
According to a spokesman for the black box manufacturer Honeywell, Ron Crotty, zadat drive recorder technology (solid-state) is more reliable than its predecessor, the magnetic tape. Solid state memory chips so no moving parts that must be like a round tape. With no moving parts, maintenance is easier. Damaged during the accident risk was decreased.

Data from the CVR and FDR are stored on the memory board on the inside of the collision-resistant memory unit (CSMU). CSMU a cylindrical compartment on the recorder. Memory boards about 4.45 cm in diameter and 2.54 cm high.

This memory board has a storage capacity of digital data that can accommodate audio data during the 2 hours CVR and 25 hours for flights to FDR.

Aircraft equipped with sensors that collect data. This sensor detects the acceleration, velocity in the air, altitude, outside temperature, cabin temperature and its pressure, engine performance, and more.

With a magnetic tape recorder can keep track of 100 parameters, while solid-state recorders can track more than 700 on larger aircraft.

All data collected by the sensors is sent to the aircraft flight data acquisition unit (FDAU) in front of the plane.

These devices are often found in electronic devices under the cockpit. FDAU a middle manager for the entire process of data recording. This unit carries information from the sensors and sends it to the black box.

The second black box supported one of two power plants that draw power from the engines. One generator has a 28 volt DC power source. One more 115 volt and 400 Hz AC power.

According to the Technical Director for the company's flight recorders L-3 Communications, Frank Dolan as quoted from Howstuffworks.com, standard equipment that the aircraft power supply.

Disaster Resistant
In various plane crashes, the only one who can survive only collision-resistant memory unit (CSMU) from the flight data recorder and cockpit voice recorders. Usually, the rest of the chassis and component parts of the recorder was destroyed.

CSMU is a large cylinder that was soldered to the recording of data. The device is designed extreme heat resistance, lacing, and pressure up to the ton.

Using three layers of material, CSMU in a black box to protect the solid-state memory to store the board pile of digital information. Here are some of the barriers that protect the flight of valuable information:

Wrap aluminum: there is a layer of aluminum around the stack of memory cards.

High temperature insulation: dry silica material has a 2.54 cm thick. This material is able to protect from high temperatures. This is what makes the memory boards are safe to fire after the incident.

Stainless steel shell: This material contains a high temperature resistant stainless steel layer 0.64 cm thick. Titanium can also be used for a black box clothes iron protective device.

According to L3 Communications, a black box technology will be increased. Development which has been reported to be able to record video activity in the plane.
