An accident aircraft could possibly be gyrating through any axes before impact and thus unable to reliably stream data. The last moments of an accident flight tend to be the most critical to preserve. With current technologies, only a local storage device onboard can reliably store telemetry data when not in stable flight.
Emphatically disagree. Ask Rolls, who monitor their engines like they are separate from the airframe. In flight, the engines report in real time to a complex in (Devon?). If the data on the airframe can be streamed like Rolls does, the problem is solved. As an investigator in another life, I have been skeptical of the “authority” role in post crash research.
Almost like the truth is to be avoided....
