The Federal Aviation Administration issued an emergency order on March 13th grounding all Boeing 737 MAXs, citing new information displaying a doable hyperlink between the crash of a flight and theft. Ethiopian Airways on March 10 and that of a Lion Air airplane off the coast. Indonesia final October. In an interview with NPR's David Greene this morning, FAA Appearing Director Dan Ewell stated that "lately refined satellite tv for pc information" from a flight telemetry system had led the company to make the transfer.
Ethiopian Airways flight 302 and Lion Air flight 610 (JT610) had been lately acquired from 737 MAX eight plane, and each had been misplaced on board simply minutes after takeoff. In keeping with the emergency order issued by the FAA, "new info from the wreckage in regards to the configuration of the plane simply after takeoff", mixed with lately refined information from the satellite tv for pc monitoring of the flight path of the plane, point out some similarities between the accidents of ET302 JT610 this warrants additional investigation into the potential of a standard trigger to each incidents that he must be higher understood and handled. "
The information in query comes from a mixture of telemetry sources from the Computerized Dependent Surveillance (ADS) system of flights. Launched in the USA in 2001 and extra extensively world wide after the Malaysian Airways Flight 370 crash in 2014, Europe has compelled most planes to hold ADS-Broadcast (ADS-B) UHF band since 2017, in addition to the FAA. mandated ADS-B for many plane by 2020.
Whereas the ADS-B information was initially to be collected by different plane and floor stations, they’re additionally tracked by satellites. Different much less detailed telemetry information despatched in subscription-based ADS-A / ADS-C (ADS-A / ADS-C) format, the long run air navigation system (FANS), and addressing and reporting system Plane Communications (ACARS) are additionally captured by satellite tv for pc.
The investigation will not be over and a direct hyperlink between the collisions will not be sure. Witnesses of the accident on ET302 stated they noticed smoke popping out of the airplane earlier than the accident. Nonetheless, the vertical velocity profile of the ET302 transmitted by way of the plane ADS-B telemetry indicated a sample of sudden dives just like that of the JT610. The ADS-B information recorded for ET302 by FlightRadar24 exhibits that after reaching an altitude of eight,025 ft, the plane plunged all of the sudden, plunging to 400 ft earlier than recovering briefly. However the plane's vertical velocity remained unstable and some minutes later he plunged into the bottom.

The ET302 broken flight information recorder was despatched to France for later evaluation. The FAA and the Nationwide Transportation Security Board (NTSB) assist the investigation.
