从技术角度讲,让飞机实时传输飞行数据流是可能的。航空公司一直不愿意这么做,是因为飞行途中发生事故的情况比较少见,而实时传输数据流价格不菲。但在马航370航班失联带来的震惊中,航空业和航空监管机构开始意识到改变的必要性。
In the spring, the Malaysia Transport Ministry issued a preliminary report on Flight 370 with a single recommendation: that the United Nations’ International Civil Aviation Organization examine the safety benefits of introducing a standard for real-time tracking.
今年春天,马来西亚交通部(Transport Ministry)发布了关于马航370航班的初步报告,报告中唯一的建议是:希望联合国下属的国际民用航空组织(International Civil Aviation Organization)评估引进实时追踪标准的安全益处。
The International Air Transport Association has released its own voluntary standard: Within one year’s time, all aircraft should report their positions at least every 15 minutes, and more often during emergencies. There’s reason to suspect that the 15-minute standard, which is far short of live-streaming, is too lax. In 2009, Air France Flight 447 disappeared over the Atlantic. Search crews found debris within days, but it took nearly two years to recover the “black box” containing flight data. That aircraft had been programmed to transmit its position every 10 minutes.
