Two thousand black box parameters from planes that do not crash can be harvested via computer analysis to further increase airline safety. Cynthia Graber reports.

飛機失事沒有碰撞的兩千個黑盒子參數將通過計算機分析獲得，將進一步提升航空線的安全性。辛西婭·格雷勃報道。

The little black boxes in airplanes provide useful information after a crash has taken place. Now researchers have devised a way to use black box info from planes that do not crash—to help prevent accidents from ever happening.

飛機上的小黑匣在撞擊后提供的有用信息已經形成。新的研究者們已經找個一種途徑-利用飛機上沒有碰撞的黑匣子信息-去阻止有可能發生的事故。

Some airlines already use a program that checks 88 flight parameters in the black box. But a Boeing 787 can record 2,000 flight parameters. So the researchers employed what's called cluster analysis. They took data from 365 flights of Boeing 777s in a month of operations of a now-defunct European airline. They filtered the data into clusters, groupings of flights with similar patterns. Any data points outside of normal operations appeared as an anomaly.

一些航線已經運用一個程序檢查黑匣子的88條飛行參數。但是一架波音787可以記錄2,000條飛行參數。這樣一來研究者們就可以使用所謂的聚類分析。他們從一個月內失事的歐洲航線的波音777中提取了365條飛行記錄。他們把這些記錄過濾并按相似的模式組合。所有外顯的正常操作的數據都顯示很不正常。

The information generated identified three problematic flights. In one, for instance, the data showed that the pilot had trouble rotating the plane during takeoff.

這些信息可以得出三個飛行問題。比如，一，數據顯示飛行員在起飛時飛機的旋轉有問題。

The system can identify anomalies that suggest both physical and operational issues—such as those that caused a runway accident in Chicago in December 2005.

系統能識別物理上的和操作上的不正常-比如說2005年12月芝加哥的飛行事故是由跑道原因引起的。

The researchers from M.I.T. and Spain will present their paper in October at the 30th Digital Avionics Systems Conference in Seattle. Because to prevent future accidents, you might have to think inside the box.

來自麻省理工和西班牙的研究者們會在10月份的西雅圖《數據航電系統聯盟》上發表他們的文章。因為，要阻止事故的發生，你必須要認真考慮盒子的內部。
