Emirates 777 sent flight data after crash landing

The crashed Emirates 777 wirelessly transmitted critical flight data within minutes of the accident to airline officials, the supplier of the data storage and transmission device says.

Raul Segredo, president and chief executive of Avionica, says the device spared safety investigators a search through the wreckage for the flight data recorder to recover immediate data about the last seconds of the landing sequence.

Miami-based Avionica supplies the miniQAR Mk III quick access recorder for the Emirates 777 fleet. The device receives flight information from the same databus that feeds the flight data recorder, Segredo says. The device is linked to a 3G wireless transmitter.

A key feature of Avionica’s design may have made the speedy data transmission possible despite the crash landing. Similar devices are programmed to begin transmitting data after the landing gear have touched the runway, Segredo says. The miniQAR MK III uses a proprietary algorithm that uses a mixture of parameters to determine when to activate the data transmission on the ground, he says. Emirates officials have confirmed to Avionica that the device worked on the crashed 777.

Flight EK521 crashed shortly after confirming landing clearance on runway 12L. The 777 came to a halt on its belly.
