caption A Boeing 737 Max 8. source REUTERS/Jason Redmond Ethiopian transport minister Dagmawit Moge told reporters on Sunday that an evaluation of the black boxes from crashed Boeing 737 Max 8 jets in Ethiopian Airlines Flight ET302 and Lion Air Flight JT610 showed “clear similarities.” Flight ET302’s black boxes were flown last week to Paris for evaluation by the BEA, France’s highly-respect aviation accident investigation agency. An airliner’s black boxes refer to its flight data recorder and cockpit voice recorder. They are bright orange instead of black.

Here’s what a black box really is.
Black box repack
In the five days since Ethiopian Airlines Flight 302 crashed a few minutes after taking off from Addis Ababa, killing all 157 people aboard, regulators around the world have grounded the Boeing 737 MAX 8. That’s a reaction to the fact that the circumstances of this disaster match those of Lion Air Flight 610, another 737 MAX 8, which crashed into the Java Sea in October, killing all 189 occupants. But to find out what actually brought down the Ethiopian jet, investigators must get to the vital data stored on the plane’s two black boxes. Those boxes are the flight data recorder and cockpit voice recorder. Both use solid state hard drives, with memory cards on a circuit board. The first logs all the details that together provide a picture of everything the plane was doing as much as 25 hours before a crash: the positions of various switches, engine settings, airspeed, altitude, and more than 1,000 other parameters. Examine that data, and “you know what happened to the … [Read more...] about How Investigators Pull Data off a Boeing 737’s Black Boxes

By Andy Pasztor The Wall Street Journal Thu., Feb. 7, 2019 Honeywell International Inc. is introducing a new line of aircraft cockpit and flight-data recorders that offer more data-storage capacity and the ability, for the first time, to use satellites to retrieve accident information in real time. Honeywell officials and other proponents of the new technology said the devices, commonly called black boxes, promise major benefits for future plane crash investigations. Such options have been debated for years by aviation industry officials, and have been championed by many safety advocates and accident investigators. The aim is to ensure vital crash data can be gathered quickly, avoiding the uncertainties of lengthy and sometimes fruitless searches for conventional recorders. Without satellite data-streaming, investigators so far have had to find and physically recover black boxes—sometimes from miles underwater or remote mountain peaks—before being able … [Read more...] about New black boxes offer ability to send real-time data from plane crashes
The airline black box is getting an upgrade for the Internet of things and data analytics age. Honeywell and Curtiss-Wright are planning to use satellite connectivity and streaming data to reinvent the airplane black box recorder. The airplane black box is designed to record flight data and give investigators key information in the event of a crash. The problem with the current black box approach is that investigators often struggle to find it after a crash. Honeywell and Curtiss-Wright plan to launch next-generation Cockpit Voice Recorders (CVRs) and Flight Data Recorders (FDRs) that are always connected. For airlines and aircraft manufacturers there will be an option to access aircraft data to improve maintenance and operations. In other words, the airline black box will become more data driven, timely and able to plug into the Internet of things like other sensors.
