ADSB Aircraft IDs

[ATCTech]

Another example of why what is entered into the aircraft FMS by the flight crew as the flight ID is not seen by ATC. As I've stated previously, ATC radar display data tags are derived exclusively from the Mode-S or Mode-C transponder code being correlated with the ACID (AirCraft ID) provided on the officially filed flight plan.

A P180 is a jet?

You'd have to ask Jimmy....

The FAA is threatening enforcement action against pilots doing that and sending out threatening letters. They're sick of it (and rightfully so)

I've seen N, TEST123, ASSH6073, and many other nonsensical things.

ATC radar display data tags are derived exclusively from the Mode-S or Mode-C transponder code being correlated with the ACID (AirCraft ID) provided on the officially filed flight plan.

The time that differs is where there is no filed flight plan, or the aircraft is not being tracked. In those cases, the ADS-B is used. There are even some times (though rare) when tracked aircraft will generate a ghost target, in which the ghost target is the ADS-B call sign.

While that statement in and of itself is true, that is only for the radar tag and the beacon code assigned by ERAM (or local subset bequeathed to terminals from the center). TRACONs using STARS (an automation system in the US) *can* see ADSB callsigns. We've done it often for Class B violators.

The blank green button (top left) on the keypack or slew/enter combo on a non-discrete works.

ERAM is the same. You can switch between beacon code and ADS-B callsign if it is being broadcast.

ADS-B Exchange direct from a browser here. Still learning, but it seems to be my "go to" for military aircraft. Unable to add much to the thread but I saw a helicopter last week with a "ghost" target shaped like a jet following it around. When the heli flew past my office it was plain to visually see it was a lone aircraft.

There are times with the online sites that they will display ADS-B positions and perhaps either corresponding FAA radar returns and/or MLAT position calculations, resulting on the ghost target. Not a major issue but it does happen.

I see that a lot with USMC Ospreys that used to fly over my humble abode shaking the foundations. Recently, though, they fly over emitting less noise than a Blackhawk at the same altitude approximately 3500 feet. Maybe those jarheads finally learned how to fly 'em...

I neglected to suggest that if you're using a site that allows you to select ADS-B, MLAT or other sources of tracking data simulataneosly that this too can cause multiple targets for the same aircraft. I've tripped myself up on that one in the past having multiple data source types "on" and seeing the same aircraft in very close proximity to itself, sometimes under a different data tag name. (ADS-B vs. ATC display tag for example)

A co-worker lives right underneath a VR Route. It's just infested with Chinooks and Ospreys. They are LOUD!
