Inaccuracy in Flight position

Today (23rd Oct 0935 UTC) i tracked AI 144 KWER to VABB. The Location of flight was totally different as seen on my Local DATA of ADS B and as shown on Flightaware (as ESTIMATE). Why Estimate data when Live feed is active and available.

Link to the flight?

Your data is here: … Z/tracklog
Not sure offhand why that generated a position-only flight segment rather than merging it with the existing flight.

edit: I’d speculate that the bogus planned route via Mongolia meant that your position data was considered too far from the expected route and so was split off into a new flight. if you look at the previous day’s flight: … /KEWR/VABB then you see that it has a better planned route and it’s picked up your data there.
