Rescue team found the black box AirAsia, five things about the black box

Black box consists of two devices that function to record flight data and cockpit voice.

Head of the National Search and Rescue Agency, Bambang Soelistyo, said the joint search and rescue team managed to take the flight recorder data is known as the Flight Data Recorder (FDR) which is part of the plane's black box AirAsia QZ 8501.

"I conclude flight data recorder was found. Its still trying to look outside of the main tasks is the cockpit voice recorder," he said.

Bambang explained, the data recording SM-cost serial number 000556583 is part of the black box, aka the black box.

"In the black box there are two equipment, a flight data recorder that records all data in flight. Cockpit voice recorder is a device that records all conversations in the cockpit," he said.

Data recording the flight, said Bambang, found under debris wing and evacuated on Monday (12/01) morning by a team of Navy divers consisting of Captain Saiful, Niles Bambang, Sergeant Rajap, Kopda Edi Susanto.

Two black box is usually located near the tail so the chance to survive the collision is high enough.

One of the black box has a working microphone to record a variety of sounds from the cockpit. Not only the pilot and co-pilot voice conversations are recorded, but also a variety of important clues, such as engine noise, sound the alarm, even the sound of a chair that is shifted if the crew moves.

Other black box function to record thousands of data that gives an indication of the movement of aircraft, such as speed, height of the surface of the earth, strength, and so on.

The mystery of why the crash AirAsia QZ 8501 will be missed after the black box analysis - which takes months.

Five important things about the black box

Flight record data includes a variety of data plane while flying, including speed and engine conditions.

Joint search and rescue team managed to take the flight recorder data is known as the Flight Data Recorder (FDR) QZ8501 AirAsia plane, on Monday (12/01) morning. However, did you know that FDR is just one of the two parts of the plane's black box? Here are five important things about the black box.

There are two devices in a black box

Head of the National Search and Rescue Agency, Bambang Soelistyo said there are two devices in a black box. The first part is the flight data recorder that records all the data while flying, including aircraft speed, height from the surface of the earth, strength, and so on.

The second part is the cockpit voice recorder which records all conversations in the cockpit. Not only the pilot and co-pilot voice conversations are recorded, but also a variety of important clues, such as engine noise, sound the alarm, even the sound of a chair that is shifted if the crew moves. The maker of the black box from the United States, Honeywell, said recording lasted only two hours from the last position of the aircraft.

There are two devices in a black box.

Black box, but orange

When first created by Australian scientist, Dr David Warren, in the mid-1950s, the box containing the data recording painted black. However, to facilitate the investigators found, the box was later painted orange. The device is usually located near the tail so the chance to survive the collision is high enough.

The black box later painted orange so that investigators can find it easily.

Short battery life

Steve Brecken, director of media maker black box from the United States, Honeywell, said battery black box most of the 30 days old.

This is confirmed also by the senior investigator of the National Transportation Safety Committee (NTSC) Prof. Dr And against Siswosuwarno, which handles the investigation of the crash of Adam Air in Majene waters, West Sulawesi on January 1, 2007.

Hence the fact that, the rescue team must race against time to be a black box could be found. According to Steve Brecken, both flight data recorder and cockpit voice recorder has a Local Emergency Transmitter (ELT) or emergency signal transmitter. When submerged in the sea, the ELT function is replaced with Underwater Locator Beacon or ping pinger that emits signals.

not float

The black box is made of aluminum, weighs 10 pounds, and has a length of 49.7 centimeters. Because of its weight, the black box can not be directly float and sink to the ocean floor. Therefore, when the Air France flight AF 447 crashed into the Atlantic Ocean in 2009, the new search team found the black box in the mountainous areas under water in the Atlantic Ocean, two years after the crash.

length analysis

Once found, the black box will be analyzed by a team of investigators transportation Indonesia and France as well as teams from the black box maker Honeywell company. According to Greg Waldron, managing director of consulting firm Asia Global Flight flight to the BBC Indonesia, the analysis process will take months, maybe even a year.

The analysis should be done carefully and recorded using a video camera given the data from the black box that very much, include aircraft engine condition, whatever the pilot, the exchange of information from the control tower to the ground plane, and so on.

"The results of the analysis will be set forth in the report, hundreds of pages. However, early reports from key points may be found in the next few weeks, "said Waldron. (BBC)
