The Search of MH370 with Geographic Information System

Airplane is known as the safest transportation that you can use. It said
 that the chance of accident happen during airplane flight is only 1 in
million. It’s way safer than land transportation. As we all know, the
number of people killed on the road in a year is way higher than the
number of victim of war. However, few weeks ago, there is big news
related to this air transportation. Yes, you must know about MH370
flight crash. The most interesting part of this accident is the crashing
 location. The MH370 flight was originally flying from Kuala Lumpur to
Beijing. However, because of some reason, this flight turned around
their route and fly to the Indian Ocean, West of Australia. More than
that, there is indication that pilot turned off the signal that can be
used to detect the location of the airplane. From this point, there were
 many issues and opinion about this case. Some experts said that it was
technical error and the hottest issues that moment was hijacking
accident by terrorist. It make sense, because, there were two passenger
of MH370 using fake passport to take that flight. Now, after some debris
 of this airplane has been found in Indian Ocean and there are four
signal that is predicted to be the black box signal, was detected, the
search for MH370 will continue. There are many ways that can be used to
find MH370. One of them is Geographic Information System (GIS). This is
also the system that helps to pinpoint the location of MH370 in Indian
Ocean. As we all know, the last signal of MH370 was detected in Malacca
Strait. This is also the reason why this case becomes the hardest case
in air transportation history.
 The Geographic Information System
 The GIS itself is a system that use many data and factors, which is
usually related to the geographic location of some event, to find the
fact about some event. In MH370 case, there are various data and
parameter that has been used to determine the exact location of MH370.
For example, the last detected signal, the climate at the moment the
accident occur, the airplane factor, and many more. This case is similar
 with the Air France case few years ago. However, the different is, the
last signal of Air France that was detected is really close to the
crashing location of this airplane. However, MH370 take about 2000 miles
 to the South of its original destination, which makes it really hard to
 find. The GIS collect all these data, including the trace of airplane
engine signal that was detected by British satellite. With this data,
the searcher can say that the MH370 was crash landed in Indian Ocean.
The data that expert got to conduct the search with GIC method was also
acquired from the online global mapping that we can found on many
websites. Many people all around the world use this method to look at
the Indian Ocean and try to find possibility that there is some debris
of MH370. In fact, the first information about debris came from this
method.
 GIS Data
 Like mentioned before, the most important data that can be used in GIS
in searching for MH370 is the signal lost data. It was last detected
above Malacca Straits. From here, there are many possibilities that we
can find. However, the most reasonable cause it happened is because, the
 transponder, which is the device that sends this signal, was turned
off. This device is located inside the cockpit. And, in commercial
airplane like MH370, the only person that can access the cockpit was
only pilot and co-pilot. Other person who wants to enter the cockpit has
 to get permission from the pilot. Therefore, according to this data,
the expert say that the pilot was turned off the transponder or pilot
was under a threat, so, he had to turn off the transponder. The other
data is the flight conversation. Pilot reported that the airplane and
flight was okay, there is also no problem and everything was normal.
However, after pilot reported this information, the signal was lost.
But, the aircraft tower detect before they lost completely, there is
indication that the airplane was turned around and try to go back to
Kuala Lumpur. This data means that there was some defect, problem or
malfunction on the airplane. According to the right procedure, pilot has
 to turn around and land on nearest airport. With this data, the expert
can predict that MH370 fly to the Southeast or Southwest direction.
However, the possibility of MH370 was flying to Southeast direction was
eliminated, because the military radar in Indonesia hasn’t detected
anything. Therefore, many countries that join the search were focusing
to search on the opposite area. However, there is new data entry from
British satellite that captures the trace of signal of MH370 heading to
the southeast. This seem not possible, because, how comes this plane can
 fly through Indonesia undetected. But, this data has been used by the
expert that they try to locate the exact location of this signal trace
until it’s lost. Then, Indian Ocean becomes the place where it last
detected and debris of MH370 was found in this area. Plus, US ship also
detect ping signal on four different locations in Indian Ocean that can
become the signal of black box of MH370.
 Current Situation
 Although the battery of black box is running out one month after the
crash and today is more than one month, Malaysia say that they will keep
 looking for MH370. With all data that they got and now, they also get
3D model of the area where the last ping of black box was detected, they
 believe that this plane will be found soon. This case also becomes the
lesson for this industry and also the world. Now, many experts suggest
that every airplane has to be equipped with signal that can be detected
by satellite and can’t be turned off. That way, the accident like MH370
won’t happen again.
