Solid State RADAR

Any one who thinks that primary radar is old and out of date should grab their ears and pull their head out of their ass! It keep me from being involed in a Midair with a Northwest DC-9 and a non txp equipped Cessna Agcat out side the Chicago 30 NM mode C vale.

Its not.

Not yet.

Well I'm assuming you guys have PERF scenarios, radar outage scenarios?

You can lose one plane just as easy as you could under ads-b?

My understanding is that ads-b equipment is "supposed" to get so cheap and so affordable it will replace even mode C transponders in the near to medium future.

I'm not strictly speaking gps direct routes either, I have an in depth knowledge of terminal control for various different reasons but you are correct I'm currently an Enroute guy.

Maybe the 15 year is optimistic but technology is rapidly advancing and the ability for ADSB to replace radars for civilian applications is a real possibility, even for terminal control, were talking fidelity that updates target position faster, more frequent and more accurately than any radar system can, and at a fraction of the cost.

Are there pitfalls? Absolutely. Do I have the answers? No, but given the rapid advance of some of this technology I imagine those who do work in those fields have Or will have ways of making it work as good or better than current systems.

Radar failure scenerios? Nope. Non radar is taught in two terminal facilities that I know of in the states.

I'm not going to pretend I've read all you've wrote since my last reply.

I'll reply respectfully in full if you can tell me you've never worked a Cirrus without mode C failure. Those things in my experience are bags of garbage.

I've had a hard long day yet the oh boy Cirrus number four has a busted xponder is still burned painfully in my brain. How does this change with no primary adsb?

Watched three more jets go allegedly backwards on adsb dependant fusion btw today. Atpa can't even agree that it works. The stitching alone is horrible enough.

I'm sure it's taught at more than just Twin Falls and Helena, but yes, they are the only ones that totally rely on non-radar rules all the time. I went through a week of non-radar procedures in case we ever need to use it, but essentially all I need to do is separate the planes and issue holding instructions to them, then give the airspace to the Center. (I think I heard Erie does some non-radar in a few areas, but I can't verify that.)

We are flying over Bozeman with Salt Lake right now and he was saying they are installing new solid state radar. What are the improvements going to be with this system?

Is the radar for Salt Lake Center or a new terminal radar for Bozeman/their approach?

How homogeneous is the software and equipment between the different terminal areas? Having been on the end user side of ADS-B since its inception as the Capstone project and done a lot of glitch reporting over the years, and I can say that up here its works pretty much flawlessly now. But I took a tour of ZAN last month and was told that the Micro-EARTS they run is a one of a kind build due to it being the initial test bed for ADS-B and Wide Area Multi-Lateration. Would the Anchorage terminal software and equipment be significantly different from the stuff in the lower 48? As its also had all the bugs ironed out.

Also how responsive has the NextGen office been when bugs in the integration pop up?
 
To the limited degree I know, it is a scatter shot of technology. ARTS IIE, ARTS III, ARTS IIIE, ARTS IIIE in ACD format, STARS, MEARTS. To put the various time lines in perspective I believe ARTS III was developed around 1980 and ACD/STARS are more of a 2000 development. MEARTS is a unicorn. That's not including the Windows XP, Windows 2000, Windows 98, Windows 95 and MS-DOS devices that have to interface. Its hard to say since you toured ZAN and are asking about terminal. The bugs are real and to be honest, its hard to know how to approach it. ATPA says ADSB said that. ATPA is no perfect program either. You start the picture with 2.52 miles needing 2.5 at the threshold. You have 7 ADSB one second updates to go and the trailing aircraft is 40 knots faster, by my mind you're sending the trailing aircraft around. Turns out with the ADSB ATPA set up you'll end with 2.6 in trail. Its like you have to lose separation to even run tight.
