Year, has lost contact with two aircraft, led us to think of security, communications, search and rescue, and many other technical capabilities. Faced with successive flight safety incidents, these issues must be sufficient to arouse the attention of the airline.
Why not play a role in tracking system?
AirAsia tracking technology in the use of professional action earlier than the airline industry and promote comprehensive flight tracking system one step ahead. But unfortunately, QZ8501 yet accepted the transformation tracking systems.
Foreign media said, Inmarsat Inmarsat responsible for outreach Affairs Chris McLaughlin, vice president, said earlier this year that AirAsia installation of satellite communications equipment on some of the A320, every two minutes to provide the latest information on aircraft position. If QZ8501 can update these systems, perhaps the progress of the search and rescue work will be much faster. Up to now, AirAsia has not replied why not QZ8501 tracking system upgrades.
The same lesson also occurs in MH370 body. "Washington Post" quoted experts as saying that satellite communications, Malaysia Airlines passenger plane missing for a long time and can not determine the scope of the missing, one of the reasons is that the airline did not pay, provide critical for an upgrade worth 10$ per aircraft flight, may endless computer software --Swift system data.
In 2009 Air France crash, for example, the aircraft is equipped with the latest Swift system, relevant information for investigators to narrow the search to a radius of 64 km, and 5 days in the accident found evidence of the crash.
Why can not radar surveillance aircraft?
Malaysia Airlines MH370 and AirAsia QZ8501 easily escape radar surveillance and disappeared in the air, two incidents highlight the modern airline industry an unpleasant paradox: even the most advanced aircraft, but also had to rely on aging infrastructure ground navigation. For many pilots, radar surveillance and radio communication system has not changed much compared to the past and in the cockpit.
Aireon space-based aircraft tracking company president Don Thomas, said: "We can track our cars, track our children's cell phone, but when the plane flew over the ocean or other remote areas, we can not track." "future surveillance aircraft direction of satellite navigation and communications. In the navigation area, we need to get rid of ground radar, in communications, we need to get rid of the radio. "radar experts and aviation consultant Hans Weber said.
Why can not the black box data in real-time transmission?
QZ8501 flight in the end what happened, I am afraid to uncover the truth, only to find the black box later. But the question is: Why can not black box real-time transmission of data to the ground, the aircraft dynamics are all under control? From a technical point of view, the black box really can do it, but the economy is likely to be a problem.
Black box flight data recording, is said to have more than 700 flight data, continuous recording during the flight. Not a small amount of data, regular maintenance will take the disc to the plane download.
There cockpit voice recording, the original record only thirty minutes, and now real-time recording, it can be understood as an uninterrupted satellite phone plus real-time recording, the annual cost of each aircraft certainly reach ten million US dollars of scale, cost of this measure is not high , but does not improve security.
In addition, the transmission of such data is also likely to require strong anti-interference, confidentiality, use of this technology to the satellite, if it is military, then no problem, if involved in civil, or enough money problems.
Also related to the pilot of privacy, real-time communication, all conversations are in it, you can always listen to the ground, the pilot may infringe on privacy.
Of course, according to media reports, so far, the world has hundreds of aircraft has been configured features real-time data via satellite transmission, thus shortening the time the crash related personnel struggling to find time for cause of the accident.
Why communication system suddenly out of control?
When MH370 lost contact, there is the aviation industry have pointed out that Malaysia Airlines lost contact event indicates that the global aviation industry, data communications, data backup technology is too outdated, today's aviation industry, the technology is still in use behind the 70s of the last century!
European air traffic control organization to communicate with the frequency coordination department head Jack • Puze entitled "Let the aviation industry in the 21st century communication system using" the report had pointed out that multi-pronged strategy should be adopted to improve information exchange aviation industry. Puze that for critical flight information management, should the use of advanced automation system. He pointed out in the report, "With the number of flights rose more than expected in some areas even busier, the current voice communication has to run the limit. Aviation sector has been in the development and deployment of digital data communications begin to support and replace in the future voice communications, as the next major means of communication. "
What possible future tracking technology?
The United States is the development of David called "Next Generation Air Transportation System" (NextGen), a former Obama adviser Air Safety. Susie think this may be the best answer to avoid similar incidents in the future.
The aircraft came not only transmits a signal to the satellite, and also transferred to the nearby aircraft, making it easier to lock the specific location of the aircraft and waterways, "like several flight in the air in the air can console communicate with each other. "
David. Susie said the US regulations in 2020, all of the cockpit must be equipped with not only the technology, but had to send and receive signals. In other words, all aircraft must not only have to transmit signals in accordance with the current situation, while others had to receive signals emitted by aircraft. In MH370 and QZ8501 example, once they disappear from the radar, the other around the aircraft will be able to transmit a signal that tells where to find lost contact with the ground plane, in order to accurately identify its location.
