A pulse signal heard - but only for one and a half minute? Could that be from the missing 370 Malaysian airline black box whose batteries are reoprted to be having only less than few hours before they could die/flat?

I am following the breakign news on the internatinal news channels about the intense search of of the missing Malaysian airline - whose whereabout has been unknown for a month now. The world's high tech advanced nations have been part of the land, air and sea search but the flight debri and the black box are yet to be located.

However, as much as the inability to find the flight debris has been a big concern, the worse has been the black box or two black boxes that were in that plane. The reason why there is reason for alarm about the black boxes not been found is the fact that those in the know confirm that batteries in a black box last for at least a month. And that flight has been missing for almost the same time.

According to information from the intent which I googled and lifted as it,  A flight data recorder (FDR) (also ADR, for accident data recorder) is an electronic device employed to record any instructions sent to any electronic systems on an aircraft. It is a device used to record specific aircraft performance parameters. Another kind of flight recorder is thecockpit voice recorder (CVR), which records conversation in the cockpit, radio communications between the cockpit crew and others (including conversation with air traffic control personnel), as well as ambient sounds. In this both functions have been combined into a single unit. The current applicable FAA TSO is C124b titled Flight Data Recorder Systems.[1]

Popularly referred to as a "black box" by the media, the data recorded by the FDR is used foraccident investigation, as well as for analyzing air safety issues, material degradation and engineperformance. Due to their importance in investigating accidents, these ICAO-regulated devices are carefully engineered and stoutly constructed to withstand the force of a high speed impact and the heat of an intense fire. Contrary to the "black box" reference, the exterior of the FDR is coated with heat-resistant bright orange paint for high visibility in wreckage, and the unit is usually mounted in the aircraft's empennage (tail section), where it is more likely to survive a severe crash. Following an accident, the recovery of the FDR is usually a high priority for the investigating body, as analysis of the recorded parameters can often detect and identify causes or contributing factors.[2]
Now that you have some insight into what the black box is and its importance, one can imagine what it means not to find that device on time.

Today late afternon and morning hours in the American time - some news which can be good news in terms of recoering the black boxes surfaced. A chinese Vessel, that is part of the group oof internatinal experts busy searching underwater was reported to have heard a pulse signal that sounded as it if tould come from the flight boxes of the missing flight, but that sound was only heard for a minute and a half.

Although all eyes then turned to the Chinese vessel, not much could be disclosed at that state ad the experts onboard that vessels must also inform their government and then coordinate with the various commands in this operations before a lot could be said.

One of the points that caught my attention is the debate about it was possible to pick up a pulse signal from somwhere without identifying the debri field. This debate is infact still going on - but what is important at the moment is discover the black boxes before the batteries go flat so that it can be known as to what might have happened before the flight accident - and where its debri could be at this stage.

This post was meant to alert you on the current developments and I am sure you are already following these on the various international TV channels and online.
