As I understand it, this particular data was via GPS.
Plane gets its position via GPS but sends it to the ground receivers (flightradar) via radio transponder. On receiver's density and distance depends accuracy. The plane's black box will have more accurate position data.

FlightRadar didn't gave the GPS data on the plane's physical (geographical) position, distance traveled from the moment when event happened till the moment when plane was lost on instruments. That data could tell, to the some extent of course, in what physical state was the plane after the event. Was it able to continue normally, glide or get into free fall.
Perceval said:Avala said:Perceval said:Here's my question. If for some reason the plane's engines abruptly failed while on an slight ascending course, and the plane began to fall, or rather glide, how long would it take the plane to register a descending speed of 153km/h? 3 seconds?
Immediately. But if it starts to glide the speed would decrease gradually, or increase gradually (but much faster) if in free fall. There is a difference in fall and glide, the gliding is controlled fall. For example gliding from that altitude with good pilot, plane can travel hundreds of kilometers.
Why do you say immediately? How could a plane travelling on an ascending trajectory at 10km/h gain 153km/h descending trajectory "immediately"?
Avala said:If that was a meteorite, I would say that it was rather small and that it didn't smashed the plane at the moment of impact, but more just pierced through the hull and substantially damaging it.
As I've mentioned several times, the theory does not involve a space rock actually hitting the plane but rather the shock wave from a space rock exploding above the plane.
Because I was confused with 'register'. The plane would 'register' any change immediately, but it would take some time to start to physically behave in such manner (going down), which I now assume was the question? Also, I was confused with 'glide', in such case it would be free fall, not gliding. Fall and gliding are different. I believe I answered that with this:
Immediately. But if it starts to glide the speed would decrease gradually, or increase gradually (but much faster) if in free fall. There is a difference in fall and glide, the gliding is controlled fall. For example gliding from that altitude with good pilot, plane can travel hundreds of kilometers.
I agree with the shock wave, it would done essentially the same as if hit. I was assuming the physical hit because of lack of the meteorite's heat trail. I don't know much on the meteorite's but wouldn't be there the heat trail from the burning in the atmosphere, especially if the meteorite exploded (and thus made shock wave)? The alleged lack of the meteorite's heat trail is the only what puzzles me. Is it possible? Also it would help if they said in what altitude they registered the "heat flash". If higher in the atmosphere, that maybe would explain why there is no heat trail, but in that case it would be one very mighty explosion and the shock wave. Just applying 'everyday' logic with that, I am aware that I don't know enough on that.
