1. The approaches mentioned in the answer would end up switching to ground-based navigation on the order of 2,000 feet above the ground. My understanding is that GPS spoofing and jamming are relatively short-range.
2. I should tell you about LPV approaches, which are GPS-only down to 200 feet.
3. GPS jamming is definitely a thing. I've never heard of GPS spoofing outside of either academia or the military.
4. (OK, more than 3) Aviation GPS units are more resilient to failure than standard consumer electronics. In the event of jamming they'd alert the pilot and stop providing positions before losing sufficient accuracy.
For spoofing, I imagine RAIM would make that somewhat less dangerous (though not an expert.) RAIM is used to exclude information from a malfunctioning GPS satellite, so you'd have to spoof multiple satellites to mislead an aviation GPS.
It's generally speaking legal to stop on the side of the road in the US, at least when you are outside of a city and there is a larger shoulder. There would be signs posted otherwise...were there signs posted?
What I do know is that it's illegal to mess with your cellphone when driving in California, and you're only allowed to make calls by bluetooth if you need to make a call. So I'm guessing that's why he stopped, so he wouldn't be breaking a law...
@NathanG yes, spoofing is very hard with an intelligent receiver, it ends up being effectively the same as jamming. With low power it will do nothing, or cause a slight increase in the error circle. With higher power it will make the receiver throw its hands up and report no lock
GPS that keeps an accurate lock in the face of jamming or spoofing is in the realm of military stuff, but GPS that knows when it's being messed with and tells you not to trust it is commonly-available consumer stuff, anymore
Not sure about the "generally speaking legal" part. Most states have "emergency only" regulations for freeway parking. In California it is CVC 21718. California's wireless regulations do not prevent a driver from dialing. dmv.ca.gov/portal/dmv/detail/cellularphonelaws/index
The title says it all, really: I visit http://meta.aviation.stackexchange.com and I have no problems; I try to go to https://meta.aviation.stackexchange.com and I first get a "bad cert" warning followed (if ignored) by a 403 error.
Why is that?
@BowlOfRed Man, I am screwing up left and right on my commentary on this particular accident. It's an uncommon couple of days where I repeatedly strike out like this...
I'm going to fall back to the "just going to wait for the official report" stance and hope they clear all of this up...
