>>1682961never had one myself but I saw one on a sector next to mine. atc told a plane to descend and didn't see the one under it. nothingburger in the end though, I don't even think TCAS RAs were triggered.
a lot of Air France pilots act like they're entitled because they think they have some national privilege (they don't). some of them just politely insist on directs, some of them are straight out dicks. never had a dick on freq though, they usually act like this with Paris because they think they own the airport
>>1683319Basically our standard display is computer generated and mixes radar data together and does some kind of "mean" to display a single blip. so it's not a true radar view. in case that software has issues, we can always switch to single radar view, select one convenient radar that's near our sector and see the raw data without enriched information or flight plan correlation.
we only have secondary surveillance radars where I work (SSR), so we only detect transponders that are actively responding to our radar queries. a plane turns off their transponder, we immediately lose radar contact and we have no way to see it, only the military guys can with their primary radars (PSR) that physically detect flying objects. obviously the military need those because enemy aircraft wouldn't voluntarily answer radar queries.
so I guess I could see LEO objects if they somehow have an active transponder, but I don't think they would. But they could very well detect Concordes back in the day when they were around FL600 on cruise.
