Reinventing the black box


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.’

Malaysian Airlines flight 370 disappeared in March 2014. In spite of many searches, the plane and black box have yet to be found—leaving the family members of 239 presumed dead without closure.

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.’


  1. While having realtime access to black box data definitely has advantages, one should also consider the fact that black box information (DFR and CVR) is protected under ICAO Annex 13 and only to be used to help safety investigations. In the (recent) past confidential data has been released almost immediately after an accident by overactive prosecutors or authorities, causing the crew to be publicly convicted by (social) media and possibly hampering the investigation. In terms of predictive maintenance and tracking there are other solutions available.

  2. We can put a man on the Moon in the late 60’s yet can’t find a modern day Airliner? WTF?

  3. INVENT: a Black Box, which breaks away from an aircraft upon a crash.
    Include with it a compressed “gas” capsule which will fill a balloon around the Black Box, which will bring it to the surface in the case of an ocean or water crash.
    Such an item would surely have found Malaysia H370?

    Such a method could be used to ensure all sorts of items to the surface of any sea or ocean eliminating the extensive searches conducted to the present?
