Airlines have to stream the black box data because they have to ensure that none of it gets lost in case there is an accident. The possiblity of having this black box data live streamed has come up on the surface once again after the incident of the missing Malaysian Airlines flight. This data is extremely crucial because in instances of airplane disasters, this is the only available data which can be relied upon and flight investigaters often make use of it to reach to sensible conclusions.
Though this 'black box' has proved to be very beneficial but this use of technology has its limitations as well which probably no one paid enough heed to until now when there is frantic search for the recorders from the Malaysia flight MH370 and not to forget the time taken to find this recorder for the Air France Airbus which plummeted into the Atlantic in 2009 after it departed from Rio de Janeiro for Paris. Since the black box of the flight MH370 will stop sendign signals after 30 days, there is a higher possiblity that it may never be found. This explains why many professionals have asked for this data to be stored in cloud and one of the callings in favor of this has been from Oliver McGee who is a former scientific adviser to President Bill Clinton.
The director of research and engineering at the National Transportation Safety Board, Joe Kolly, has stated that a debate has already begun regarding what measures need to be in place to prevent the important flight data from getting lost. Other ways of bringing in changes are being reviewd by the safety regulators and the International Civil Aviation Organisation which is considered as an arm of the United Nations. An International Air Transport Association summit is going to take place at Doha and this presents an opportunity to discuss some initiatives.
