Aviation is set to become even safer thanks to real-time data transmission from black box flight recorders.
In the 1960s, the black box—an Australian invention—became mandated on all commercial aircraft. It consists of two parts—the flight data recorder and a cockpit voice recorder—but one of the problems with black boxes is that they are physically on the aircraft—if the plane is lost so too is the data.
Aerospace conglomerates Honeywell International and Curtiss-Wright are collaborating to create a new kind of black box for aeroplanes that will increase data storage and, for the first time ever, use satellite connectivity that would allow for immediate, remote retrieval of plane crash data, the two companies announced recently.
‘The new recorders would serve as a “Black Box in the Sky”,’ the companies said in joint press releases. The owners, operators and manufacturers would have the option to access the data at all times, resulting in the potential for better maintenance predictability and operational insight through data analytics. In addition, in the event of an emergency, the data on board would be quickly accessible to investigators.
The new recorders would also meet or exceed the upcoming 2021 European Aviation Safety Agency minimum 25-hour cockpit voice recording mandate and would be ‘form-fit’ replacements for Honeywell’s HFR-5 series recorders.
‘It promises tremendous value for investigators by giving them early insight into accidents,’ air safety consultant Bill Voss said in the Wall Street Journal. ‘You’re going to have some data, and you’re going to have it immediately.’
In two high-profile crashes, black box data disappeared along with the aircraft. When Air France flight 447 crashed over the Atlantic Ocean on 1 June 2009 its black box wasn’t recovered until May 2011—two years later and after $40 million was spent combing the sea for the wreckage.
‘Fortunately, they found these boxes,’ former National Transportation Safety Board inspector Greg Feith told CNN. ‘But who knows, tomorrow we could lose another airplane and not be so lucky.’
There is an ongoing debate among aerospace industry experts about the benefits of streaming data versus physical, deployable recorders, which can be ejected from a plane’s tail and float on water in case of an accident.
‘The importance of reliable cockpit voice and flight data recorders cannot be overstated,’ Ben Driggs, Honeywell’s president of services and connectivity, said. The company is working with Curtiss-Wright (which took over British black box maker Penny & Giles in 2002), ‘to design and develop the next generation of recorders that leverages our full hardware and software expertise to meet the 25-hour requirement, to identify the right information and make it available to airline operators when it’s most needed.’
