Loud aircraft last night?

IFF is an encrypted system that would not be utilized by or available to any civilian application that tracks aircraft movement.

Thanks for the clarification and your service. Few people really understand the capabilities of the P-3 Navy, operating independently, perhaps 100's of miles at sea, away from any support. On the other hand, operating out of NHZ, it was not unheard of for the crew to serve Maine lobster on board. (XP3NFO).

Thanks Descant for your service as well. I never consumed lobster on a P-3, but on one of the crews I was a part of the lead acoustic operator enjoyed cooking in the galley and would prepare a full breakfast for everyone on early morning flights. Now that was a treat!

If you want to know what is round you right now try an ADS-B app like ADS-B Unfiltered. The common tracking apps like FlightRadar24 and Flightaware delay the data several minutes and don't show all traffic. ADS-B (Autonomous Dependent Surveillance - Broadcast) is directly transmitted by the aircraft and is available for anyone to receive. Ground stations forward the information. You can also receive it directly yourself with a cheap software defined radio and some software. I live near Pease and often fire it up to see what they are up to. Military aircraft frequently don't give all details, but civil aircraft will even tell you what autopilot mode they are in.

I'm familiar with the LADD program but don't fully understand PIA. I know ADS-B receivers will still pick up the signal, but the transmitted code is temporary, so there's no way to know what plane it really belongs to, right? Am I understanding that correctly?

Right, PIA allows them to get temporary IDs that aren't associated with them. But the military isn't doing that. I don't know what controls they have on a military ADS-B transceiver. What I see is that sometimes you can see the autopilot mode and a lot of other live data. Other times you only get basic information.

LADD only works when the FAA is the source, if you look at ADS-B data that was captured by random people with cheap receivers and an Internet connection you bypass the FAA entirely.

So LADD is useless. Anyone who really wanted to could probably spot the privacy ICAO address too, because it wouldn't come back to a credible aircraft history. The only time they'd provide real uncertainty would be when several aircraft on the PIA program were in the same place at the same time. Musk has been tracked despite his best efforts.
