Why are Europe and the United States on a plane using a mobile phone, China cannot do so? -Airplane, WiFi, mobile phone-IT news

Provision for prohibition against using cell phones in the plane in flight, public opinion has been debated. Supporters argue that this is related to flight safety. Opponents say, China and Europe and the United States are the same type of aircraft, why not open cell phone use as those countries do.

Science VS rules

Zhang was a radio enthusiast, some kind of electronic products for mobile phones. Every time I take a plane, he does not turn off my cell phone. "Advanced phone, will not cause interference to aircraft. "He selected a seat by the window, with a cell phone video views. He will also open the GPS using cell phones to map to see location. "Watch the planes fly over the mountains to the sea, it is also a fun journey. ”

However, he always blocked. Even escaped the stewardess scolded, he often was criticized by with older machines. Zhang will make older popular science, talk about why the phone would not affect safety, but older people do not listen to him.

Lao Zhou was an elder. When flying, he saw a young man does not turn off my cell phone furtively. "If provided to turn off my cell phone, it should abide by the rules. "This is week old point of view.

Small and old weekly debates, public opinion on the plane "cell phone bans" in miniature. Chamberlain's main arguments is used in China and Europe and the United States the same brands and the same type of aircraft, Europe and the United States has opened a "cell phone bans", but China is a long way off.

Europe and the United States opened the plane's "cell phone bans" a long process. Aeronautical communication researcher Xie Ying introduced in 1958, the United States Federal Aviation Administration frequency modulation radio receiver can cause interference to aircraft navigation systems. Originally of electronic products such as hearing aids, electronic dictionary is also prohibited. With the rise of mobile phone products in the last century 890, phone is full in the aircraft is prohibited.

In 1991, the United States Federal Communications Commission think the scope of the use of mobile phones on airplanes larger than the scope of the phones on the ground, use the mobile phone signals will be received by many base stations on the ground, will cause interference on the ground network, also made clear the cell phone ban on request.

With the rapid development of mobile communications, wireless communication technology developed more and more fast, planes are increasingly taken into account in how to resist the interference of mobile phones and other devices. Cell phone ban was gradually relaxed. On October 31, 2013, the United States Federal Aviation Administration official, cancel the ban on cell phone use on board. Following Singapore, and Australia, and Brazil and other countries authorities also liberalised mobile phone ban in succession.

Airline:

China not to boot, free flight models in foreign countries

Reporter visits including Air China, China Southern Airlines, China Eastern Airlines, and the answer is the same: no opened mobile phone on the aircraft, not even flight patterns.

In this regard, the provisions of foreign airlines are not so consistent. Most airlines allow in-flight cell phone, but some allow texting, calling, and some only allow you to use flight mode on.

Singapore Airlines stated that in-flight use of mobile phones will have no impact on aircraft systems, you can select network connections on the flight, even using a mobile phone during the course of taxiing, takeoff and landing. Lufthansa Airlines, Qantas, South Africa aviation provides, it is possible to "airplane mode" use mobile phones, but during takeoffs and landings, many airlines are required to turn off the phone.

Some airlines allow cell phone use, but not voice or video calls, such as United Airlines, Japan's all Nippon has a similar provision. United Kingdom provisions of the Virgin are broad, "some models reach a certain height or more can turn to open international roaming and calls and send and receive text messages. "Egypt air also allows A330-300 models use phone calls, send and receive text messages and the Internet.

Lawyers:

There is no phone interference flight case

Two weeks ago, civil aviation administration of China published the revised draft civil aviation law, it is the Civil Aviation Act a major revision since its began in 1996. "Cell phone bans" exposure draft also explicitly prohibit illegal use of mobile phones. Violators could face fines of up to 50,000 yuan.

Beijing law society Executive Vice Chairman and Secretary-General Zhang Qi Huai in counsel's view, the provisions of the civil aviation law draft on mobile phones, is relatively backward.

In his view, the present effects of mobile phones on aircraft flight interference, and its extent, there have been many investigations, research, and theory. CAAC provisions of the law on this issue should include treatments for other airlines, aircraft manufacturers, all prohibitions and restrictions are unreasonable.

Zhang Qi Huai believes that because cell phones use radio and radio belong to one of the aircraft used by the band, and likely to produce harmonic disturbances. But until now, because cell phone use caused a plane without any communication, navigation case of interference.

Aeronautical communications researcher:

Ban on open is the trend

Researchers introduced Xie Ying, China domestic flights, aircraft, 93% of aircraft for Boeing and Airbus, 5% to 6% for Bombardier, Ba Hang, the rest of the 1% for the Chinese domestic airliner. Aircraft hardware, China's domestic airlines are flying planes with no difference between American and European countries. In other words, using a mobile phone abroad has opened on the machine, China domestic routes also have the same hardware requirements.

Xie Ying said that the United States zhihou, two years in most countries in the world have opened up the machine for use on mobile phones. Current opening is conditional, it is only used in aircraft flight patterns, not make a voice call, and some airlines require may not use cell phones during takeoff and landing stages.

Outlook for China's opening up machine for use on mobile phones, Xie Ying described, this is "trending", is currently in the industry for comments. But, he said, this is not a simple one, relevant to the needs of policy preparation, technical preparation. He explained that the opening machine for use on mobile phones, not just the phone look a article, look up a Word, more importantly with mobile Internet access. In this regard, technical preparation of individual airlines for in-flight WIFI, there's more work to be done.

Xie Ying stressed that the current civil aviation law of comments, it is stressed that "illegal" penalties. He said that he supports opening machine for use on a mobile phone also supports opening for "illegal use" of heavy penalties. In his view, serious misuse of mobile phone acts that endanger flight safety, even into the penalty.

为什么欧美国家能在飞机上用手机，中国却不能？ - 飞机,WiFi,手机 - IT资讯

对于飞机在飞行中禁止乘客使用手机的规定，舆论一直争论不休。支持者认为，这事关飞行安全。反对者认为，中国民航使用和欧美国家相同型号的飞机，为什么不能像那些国家一样开放手机使用。

尊重科学VS遵守规则

小张是个无线电爱好者，对于手机一类的电子产品有些研究。每次坐飞机，他都不关手机。“如今手机先进了，完全不会对飞机造成干扰。”他总挑选靠窗户的座位，用手机拍下美景。他还会打开GPS，用手机地图看看定位。“看着飞机飞过大山大海，也是旅途中的乐趣。”

可是，他总会遇到阻拦。即使躲过了空姐的斥责，他也常常会被同机的年长者批评。小张会给年长者做科普，讲一讲为什么开手机不会影响安全，但年长者并不听他的。

老周就是这样一位年长者。乘飞机时，他总看见有年轻人偷偷摸摸地不关手机。“既然规定让关手机，就应该遵守规则。”这是老周的观点。

小张与老周的争论，正是社会舆论中关于飞机上“手机禁令”的缩影。小张的重要论据，则是中国使用着和欧美国家同样品牌、同样型号的飞机，欧美国家已经开放了“手机禁令”，但中国国内却遥遥无期。

欧美国家：手机禁用直到2013年开放

欧美国家开放飞机的“手机禁令”经历了漫长的过程。航空通信研究者谢鹰介绍，1958年，美国联邦航空管理局发现频率调制的无线接收机能对飞机的导航系统造成干扰。最初对于助听器、电子词典这类的电子产品也是禁止的。随着手机产品在上世纪八九十年代的兴起，在飞机飞行中手机是全程被禁止的。

1991年，美国联邦通信委员会认为飞机上使用手机的影响范围比地面手机的影响范围大，机上使用手机的信号会被地面许多基站都收到，对地面网络会造成干扰，也明确了机上手机禁令要求。

随着移动通信的快速发展，各类无线通信技术发展越来越快，飞机制造中也越来越多地考虑如何抵御手机等设备的干扰影响。手机禁令开始逐步松绑。2013年10月31日，美国联邦航空管理局正式发布，取消机上使用手机禁令。随后新加坡、澳大利亚、巴西等国航空管理当局陆续也放开了手机禁令。

航空公司：

中国国内不许开机，国外可用飞行模式

记者探访了包括国航、南航、东航在内的多家航空公司，得到的答案都是一致的：飞机上不许开手机，即使是飞行模式也不行。

对此，国外的各家航空公司的规定却不太一致。大多数航空公司允许在飞行中打开手机，但有的允许发短信、打电话，有的只允许使用飞行模式开机。

新加坡航空说明，在飞行途中使用手机不会对飞机系统造成影响，可以选择航班上的网络连接，甚至可以在滑行、起飞和着陆过程中使用手机。汉莎航空、澳洲航空、南非航空等都规定，可以以“飞行模式”使用手机，但在起飞和降落期间，很多航空公司都要求关闭手机。

有的航空公司允许使用手机，但禁止语音或视频通话，比如美联航，日本全日空也有类似规定。英国维珍航空的规定则宽泛一些，“部分机型达到一定高度以上可以开机，开启国际漫游并进行通话和收发短信。”埃及航空同样允许在A330-300机型使用手机通话、收发短信和上网。

专业律师：

没有发生任何手机干扰飞行案例

半个月前，中国民航局公布了民航法修订征求意见稿，这是民航法自从1996年开始实施以来的一次重大修订。对于“手机禁令”，征求意见稿中也明确提出禁止违规使用手机。违反者，可能面临最高五万元的罚款。

北京航空法学会常务副会长兼秘书长张起淮律师认为，此次民航法征求意见稿中关于手机的规定，是相对落后的。

他认为，现阶段手机无线电对航空器飞行的干扰、影响及其程度，已有许多的调查、研究和理论论证。中国民航法对此问题的规定，应该综合其他航空公司、飞机制造商的处理方式，一概地加以禁止和限制是不合理的。

张起淮认为，由于手机使用的无线电与飞机所使用的无线电同属于一个波段，有可能产生谐波干扰。但到目前,没有发生任何一起因为使用手机造成飞机通讯、导航干扰的案例。

航空通讯研究者：

开放禁令是大势所趋

研究者谢鹰介绍，中国国内航线的飞机当中，93%的机型为波音和空客，5%至6%为庞巴迪、巴航，剩下的1%为中国国产客机。从飞机硬件来讲，中国国内航线正在飞行的飞机与欧美发达国家并无差别。也就是说，既然国外已经开放机上使用手机，中国国内航线的飞机也具备同样的硬件条件。

谢鹰说，在美国之后，这两年世界上大部分国家都已经开放了机上使用手机。目前的开放也是有条件的，那就是在飞机行驶中只能用飞行模式，而不能打语音电话，而且一些航空公司要求在起飞和降落阶段不可以使用手机。

对于中国国内开放机上使用手机的前景，谢鹰形容，这是“大势所趋”，目前也在行业内征求意见。不过他说，这也不是简单的一放了之，需要相关的政策准备、技术准备。他解释说，开放机上使用手机，不仅仅是用手机看个文章，查个单词，更重要的是用手机上网。从这方面来讲，各个航空公司对于机上WIFI的技术准备，还有很多工作要做。

谢鹰强调，目前征求意见的民用航空法，其实是强调对于“违规使用”的处罚。他说，他支持开放机上使用手机，同时也支持开放后对于“违规使用”的重罚。他认为，严重的危害飞行安全的违规使用手机行为，甚至应该入刑。
