Airplane is the safest means of transportation in the world, relative to the car and ship, such as land and sea transportation has a higher security. But each accident due to its severity, tend to be more and more people's attention. As the field of Internet and the emergence of new technologies in the field of science and technology is one aspect to the journey, especially long-distance journey more comfortable and convenient, but the emerging on the other hand has brought some new risks to aircraft. In-flight wi-fi At present in the world, air France, KLM, etc. More and more foreign airlines have opened a WiFi flights, Air China has started trial operation of WiFi, and completes its A330 aircraft fleet will be modified. But Air China still does not support mobile Internet WIFI. Wireless LAN security hidden dangers remain, however, if there are not enough safety, passengers can easily access the crew special network, will also affect aircraft navigation. The Times says the security hidden danger means that malicious hackers just need a laptop computer, you can sit in the cabin "hijacked" the whole plane. It is understood that the air the plane wireless network system and other systems are physical plane on respectively independent system, even if encounter hacker attacks, also won't affect the flight safety of the plane. Electronic equipment The international air transport association's latest report, by the passengers carry portable electronic products, there will be more chance to cause the crash. According to the report, from 2003 to 2009, according to the statistical data of 125 airlines, aircraft flight control system, automatic navigation system, automatic driving system, ups and downs installation and communication tools are on the plane are using electronic products. The flight risk of the electronic device, the first is popular in the world of the iPad. New electronic digital products such as the iPad have a network interface, the network interface include bluetooth, infrared, wifi, etc., which is able to at close intervals sends out high frequency radio waves, but these high frequency waves according to guess there are some close to frequencies of civil aviation. Mobile phone app Pilot Hugo Teso recently In The Hack In The Box made a speech In The Conference meeting, he said aviation security system and communication protocol of security is very worrying. He demonstrates how to use the meeting an Android device successfully remote to hijack a plane. Hugo Teso utilization is a mobile App called PlaneSploit track near the aircraft, reuse of target aircraft on its own research and development of hacker technology; Invasion of its instruction system, aircraft in flight, including direction, height, speed and flight displays, etc., even can command issued a crashed. Hugo Teso destruction mainly is the plane automatic tracking to monitor radio and aircraft communications addressing and reporting system. These two systems exist very big security hidden danger, is vulnerable to passive and active attacks, which affect the plane. Currently, Hugo Teso is only in the virtual environment test is successful, has not been used in a real plane. Mobile phone "flight mode" Banning the use of mobile phones on aircraft, the FCC (federal communications commission) is a regulation in 1991, the reason is that cell phones emit radio waves, may interfere with ground-to-air communications. Even adjusting to the flight mode, mobile phone will launch signal outward, is still possible to interfere with the frequency of the connection between the aircraft and the ground. In early 2001, NASA (NASA) compiled a report, 14 years from 1986 to 1999, the agency received 65 cases by personal electronic devices interfere with the aircraft electrical system. Last year the international air transport association, according to an internal report, from 2003 to 2009, 75 such events happen again. The plane lithium ion batteries The same concerns from a Boeing company is the latest generation of 787 "dream (Dreamliner). In order to lose weight, a Boeing 787 chose Japanese production of lithium ion batteries to replace the traditional nickel metal hydride batteries (NiMH) as accessories. But this is the lithium ion battery for its flight safety. On January 16 this year, Japan airlines and all airlines announced that due to the diurnal airways Boeing 787 failure occurs during the flight, and made an emergency landing. And the cause of the accident is the lithium ion battery is on fire, a day earlier, in Boston, another aircraft operated by the airline against fire in 787 and reason as the planes underbelly of battery fire. Although lithium battery capacity is much higher than nickel metal hydride battery, but its internal use liquid as electrolyte material, afraid of high temperature and flammable and explosive, is not suitable for used as accessories on the plane. Atc software On July 28, 2012, 26, a computer security experts warned that the air traffic control system has vulnerabilities, flashpoint for computer hackers, endanger the flight safety. Computer security expert Andre coase katyn 26 "black hat" in the United States city of Las Vegas professional network security conference, the global use of ads-b control system software has a defect, a common technical knowledge people spend about $2000 to buy electronic equipment, you can decide. Ads-b control system can make the plane and plane, plane and ground controllers to contact each other, improve the efficiency of air traffic control. However, ground controllers can't confirm whether information is sent from the plane. Hackers can pretend to be crew, give false information to traffic controllers. Toshiba PA3534U-1BAS batteri
