DG,
Hardly any Delta flights transmit ADB-S info. Today for instance, N174DZ, N175DZ,N176DZ, N177DZ, N187DZ, N188DN, N1501P, N1604DZ, all B767s appeared in MyFlights without any callsigns or other information. Only N707TW, a B757 operating flight DAL045 was transmitting ADS-B. data. Other 757s in their fleet have also previously appeared in my logs with data but apart from a couple of aircraft in the N8** series, their B767s always remain 'secretive'
Anyone know why?
Regards
Hawkeye
