AirAsia plane disappeared from the radar QZ8501 aviation
authorities of Indonesia, on Sunday morning, December 28, 2014. The Department of
Surabaya-Singapore Aircraft passenger and 7 crew of 155 people, the last time
recorded was above the waters of the Pacific at 06:16.
Some aviation experts provide insights about the cause of
the Airbus A320 aircraft disappeared from radar screens. The following theories
about the possibility of the loss of QZ8501, as reported by SkyNews, Sunday,
December 28, 2014.
1. Technical Failure
A320 has a very good safety record, with 26 incidents
experienced since it was first put into operation in 1988. According to pilots
and aviation experts Gideon Ewers, all incidents caused by other factors rather
than a problem with the plane.
The case of disruption to the A320 is the most famous bird
strike at US Airways plane owned airline of the United States was forced to
land in the Hudson River, New York, 2009. About 155 passengers survived when
the plane slowly sank in the Hudson River.
The Acting Director General of Civil Aviation said Djoko
Murjatmodjo QZ8501 just enough fuel to travel for four hours. "At least
four and a half hours long," said Djoko Murjatmodjo, Sunday, December 28,
2014.
Under these conditions, the aircraft is expected to run out
of fuel on Sunday, December 28, 2014, at 10:00, if it continues to fly after
the plane went missing from radar. AirAsia plane Surabaya-Singapore route is
estimated landed 07:57. "If you lost contact still fly, meaning that it's
been exhausted," said Djoko.

Irianto recorded radar captain asked permission to raise the
height of the control tower, before the plane disappeared from radar to avoid
bad weather. According to aviation experts captain Mike Vivian, at the height
of the storm can be rolled up thousands of feet and cloud lightning can cause
serious damage to the aircraft.
However, Vivian said, the weather conditions were changing
and strange in a specific area usually already anticipated the experienced
pilot. Vivian says an oddity on changing weather events can suddenly cause the
plane lost contact.
Acting Director General Djoko admitted AirAsia QZ8501
Murjatmodjo last report to the control tower to shift to the left and raise the
height of 32 to 38 thousand feet. When the pilot irianto claimed to want to
avoid the cloud cumolonimbus.
"For the shift to the left has been approved, but that
request was approved up because there is still air in the above, still
solid," said Djoko. Weather data in the airspace, said Djoko, is not good.
"Many cumolonimbus cloud," said Djoko. But when leaving the sunny
weather data in Surabaya.
From the observation flightradar24, then around QZ8501
AirAsia plane lost contact, there are at least two nearby aircraft. One AirAsia
plane QZ502 Department Denpasar-Singapore departing from Denpasar at 06:18.
Another is AirBus A320-233 aircraft carrier Silk Air.
3. Hampered Clumps of Ice
The plane could fly into a lump of ice that may cause the
aircraft "came out of the sky", according to Ray Karam Singh, pilots
are familiar with the route over the Java Sea.
He said AirAsia QZ8501 pilot could have tried to fly out of
the condition to climb higher, but could be even more problematic with the
situation. Singh added, the ice is the most likely cause than the storm.
4. Pilot Error
Irianto, Indonesian pilot who led the missing flight, has 20
thousand hours of flying experience. According to AirAsia boss Tony Fernandes,
seven thousand hours of flight was passed along AirAsia. He was accustomed to
flying the aircraft for short-haul routes and very experienced, according to
aviation experts to SkyNews.
5. Intentional Action
The AirAsia airline pilots maintain communication with the
control tower until the last minute. According to David Learmount, Global
Flight page editor, spell the pilot is flying, driving, and communicate. There
are things that annoy so that they can not talk to the control tower.
Learmount said there was something that distracts the pilot,
so that they can not continue to speak in the long term with the control tower.
"We did not know what was happening at the time, and if the aircraft does
not appear, there is a deliberate act."
To SkyNews, the event usually happens in the event of a
terrorist target. The situation in the cabin shows certain groups want to be
responsible and are eager to claim a "victory".
A pilot from Indonesia who are not willing to confess their
piracy issues among aviators. Allegations arose as there was no sign of an
accident, including radar did not catch the signal Emergency Locator
Transmitter. ELT is a device that sends a signal when the plane crashed.
"The tool reads suffered concussion or an emergency landing.
If the device does not ring, we can not conclude anything," said Head of
the National SAR Sutrisno East Java, on Sunday, December 28, 2014. However
Sutrisno reluctant to speculate happenings allegations of piracy issues it.
