Hi,
i noticed that Flights operated by Air Dolomity for Lufthasa under a DLH callsingn are not tracked by adsb, although they are in the coverage area. Maybe theres a possibility to change that… 
For Example DLH1946
Do they actually send ADS-B? There are quite a lot of regional flights that don’t.
yes they do, i can track them locally on my Pi.
Do you have an example of a particular flight which you can see positions for on your local Pi, but there is no FA tracking?
Yes. DLH1896 MUC-TRN
Here Just the estimated Data de.flightaware.com/live/flight/DLH1896
and here the screenshot of my local dum1090 data, that i’m feeding to you 
and also DLH1950 MUC-PSA

hmm, so theres the data from the flightplan which i can find here de.flightaware.com/live/flight/ … 0617/0919Z These two links show the same flight. Why aren’t these data matched togehther?
