Thanks, I am fighting with Excel as well.
DaveReidUK is right with the uneven distribution over time. But still we can see that the Groundspeed is not one or two glitchy datapoints but somehow a continuous increase in the last 7 seconds (speed stops to decrease at 5600ft, starts to increase again at ~3000ft)
Why is the question. GS surely is calculated. From INS? What happened to the sources for INS? Was 735 retrofitted with GPS anyway?
I'm also (and always) sceptical with FR24 collected data, you have a first but somehow fuzzy picture.
Only the ALT drop seems to be realistic. that's "impressive" unfortunately.
I don't read more from it at this time.
