It is if you are an exec in a publicly traded company. Where you travel can be considered insider information, and disclosing that information is a violation of federal law. Just ask Martha Stewart about how that works....
Yes, she's OK with her whereabouts being public and all-over social media if it's about her concerts or celebrity appearances but if that public info is about her jet - cease and desist! As for the guy mentioning the license plate issue, most people that own jets (speaking from experience lol) don't have the registration in their name - most of the time they're registered to a company.
Again, if you are an exec in a publicly traded company, and you cannot figure out how to shield your travel info with corporate structure such as an aircraft leaseback, then you probably should not be an exec in a publicly traded company.
I'm not sure if you're arguing that government transparency requires that nationwide ADS-B data dissemination be facilitated, as is generally currently the case, or if you're arguing that its not a privacy concern because the methods to circumvent this dissemination are so easy and readily available, in which case the dissemination itself seems pointless.
ADSB requires an operating mode C transponder, so if the ADSB is reporting one position and the radar/transponder is reporting something different...
It's not about whether it's possible to shield the info. It's about a reasonable expectation of privacy.
Because it was convenient for a couple of engineers when they wrote the specification. (said sarcastically, I have no idea if there was a reason, I just have not seen one, and it makes no sense to me from a cyber security view)
The real answer probably isn't too far off from "Because we could." Digitization of the data and massively cheap computer storage makes it possible to save and search lots of "Big Data". I imagine this is a small and relatively insignificant example.
How does publishing real time flight tracking on the internet provide safety?
Mode S can be tracked as well via a process called “multilateration”.
Because we could, and inertia are the most likely answers. ADS-B actually dates back to the late 90s if memory serves. But at no point did the FAA every think about updating it to deal with cyber security, privacy or anything remotely related.
What they do is drop the case if you appeal it to Federal court.
The government does not publish ADS-B on the internet. FlightAware obtains that information from crowd-sourced ground based receivers, which it cross references with flight plans via ASDI.
If you do add it to the ASDI block list, I would advise the “source blocking” option since the FAA will literally give the feed to anyone who asks.
We're probably only a couple years away from fully automated real time transcription of LiveATC feeds given the current state of machine learning.
I repeat. The cops still have to interview him when the complaint is made. She didn’t tell the cops she was using adsb, she would just call them when she got the alert and claim he was circling her house. The guy had to show them every time that he was not.
That's not substantially different from photo-based radar used for traffic tickets. The responsibility lies with the owner/registrant of the vehicle until proven otherwise.
True, and stoplight cameras are effectively illegal here in TX.Except that’s not standard across the 50 states.
Not likely to see it on my plane. I've got small (non ADIZ) numbers.
It's not required by law, it's just not prohibited (like airman data which is SUPPOSED to be covered by the privacy act that the FAA just decides to ignore).
Alas, that also is not true. Specific parts of the RF spectrum have indeed been regulated by law subsequently (notably the ECPA).
MODE C or MODE S to get a position requires you to use active radar... you know, a spinning antenna that can send the interrogation and figure out where the reply is coming from (and suppress the false returns that come from that system). Getting the identity and position from UAT or mode S ES just requires a passive receiver.
This can (and is) done with amateur receivers working together by ADSBexchange, FlightAware, and other sites.
That means that every mode C (and S) plane out there will respond to the interrogation at once? How is that resolved? I understand how you could do it with mode S.
All Mode C transponders at the same distance from the interrogator will get the interrogation signal at the same time on 1030 MHz. After a 3 uSec delay, each transponder will start the transmission of the reply on 1090 MHz. Each nanosecond of time difference represents one foot of additional distance from the receiver. Precision to the nearest 0.2 NM is what the surveillance requirement is with ADS-B, so that is to the nearest 1.2 microsecond. So although aircraft at the same distance from the interrogator will generate a reply at the same time, the distance to each of the multilateration receivers will be different when the aircraft are not at the same position. The multilateration receivers are going to be able to see aircraft responding to the same interrogation because of the very precise time differences they use to determine the position. My understanding is that ASDEX ground position radar uses similar technology, because the round trip time for a transponder query to reply is too imprecise. The 3 microsecond delay alone between the end of the interrogation and the beginning of the reply is more than a half mile in position, so precise timing is used to triangulate the position of the aircraft on the ground.
there is no law or federal prohibition from yelling 'fire' in a theater.
The fable about smallpox blankets is just that - a fable. There is zero evidence that it ever actually occurred. In fact, the history professor who first wrote about it was fired from his position at University of Colorado for fabrication and falsification of evidence in conjunction with that very myth.

Neither is true. There is no verified factual account of the blankets legend. In the Tuskegee Experiement, no one was injected with syphilis. People who had syphilis were not treated, but no one was given the disease.
