Significant speed drop

Hi guys,
I’m currently tracking the flight KL591 from Amsterdam to Johannesburg

and I noticed a very significant drop in speed (to 698km/h). I don’t have any aviation knowledge whatsoever and was hoping someone could maybe explain :slight_smile: Thank you in advance!
Best regards

Sarah

I think you have seen a measurement error, when checking is is on it’s normal speed again.

If you check the indivual log, you will find the single entry.
Seem to be a tracking error, not really an aircraft problem

If you look on the map that was the time where the tracking moved fro a “green” to a “white” line. I assume tracking was lost. at this time:

Checking Flightradar there is no drop:

Thank you guys so much! It’s a big relief :slight_smile:
