Didn't see this posted. If it has been enjoy again. :)

Here's a video and at the link there is a comparison chart. Pretty much equals the Stratus 2s and includes a carbon monoxide detector.

Made by the same company as the Stratus?

If not I wonder what they did to make ForeFlight mad, since Foreflight always wanted sweetheart deals with commercial expensive stuff and blocked stuff like home brew AHRS in Stratux devices.

Oooh they got into bed with someone else.

Wonder if Stratus will file for divorce? :) :) :)

I think so... saw something on another board hinting at that the next model Startus will work with the other popular EFBs
 
Can't beat that price though for the same function and a carbon dioxide detector. $400 cheaper. Wonder what Stratus if anything will come up with to combat it? And I wonder if Sporty's will sell it.

Maybe the same function. That box looks pretty small for decent antennas. It’s probably a bit “deaf” on receive but “good enough”.

It’ll lull someone who hasn’t studied how this NON-safety engineered system works, into the same false sense of security that my expensive certified one in the panel tries to do to me.

I know better. Lots of people don’t. They think they’re going to see all traffic or worse they think the weather isn’t delayed. All sorts of misconceptions that don’t match the (lack of) engineering effort behind ADS-B.

Still double the price of a DIY Stratux too, but at least it’s closer than the Stratus was.
 
I woulda bought one, but it's from California. Just can't swallow that fact.
 
Wonder if it accepts an external antenna? I didn't see that feature mentioned or in any pic.

What can they do about that? AFAIK, the math is the same as we use in microscopy to deconvolve 3-D images. It takes a fair bit of time to both generate the data and then make that mess of radar returns into meaningful data. Other than attempting to educate people, I don't see much that can be done about it, but I'm willing to learn otherwise.
 
FF and Garmin are pushing hardware and after 2020 you going to pay ransom for service.

Nothing. The public just thinks that what they see on their phones is in real time and it carries over negatively as a trained experience to the cockpit where the delay can be much higher and more life-threatening if they don’t understand the limitations of a data network essentially designed in the late 90s being marketed as “new tech”.

Their expectation of “new tech” is what’s in their pocket. Not 1996.

No..... from this page. https://foreflight.com/support/sentry/

WHAT COMPANY MANUFACTURES SENTRY?
Sentry is manufactured by uAvionix, an innovative avionics company based in Palo Alto, California.​

They heard your complaint and moved to Montana.

Apparently Foreflight didn't get the memo. Hopefully the post office is still forwarding the royalty checks. :)

I'm sorry, I still don't understand. The collection and processing of the data is completely separate from the data network. The data collection and processing is non-trivial and that leads to the delay in the data being presented. They need to:
  • Do a sweep with the radar
  • Detection and removal of artifacts (ducting, multi-path returns, insects, wind turbines, etc)
  • Adjust for the data being smeared in volume for more distant returns
  • Do a sweep at a different angle and repeat the calculations above
  • Combine the data with other radar systems
  • Generate the presentation
None of that has anything to do with getting the data from the ground station to the plane and I understand the bulk of the delay is in those steps above. There are almost certainly more steps involved than I listed above.

You aren't explaining, in a way that I understand, how the data network is contributing to the delay in data presentation to the pilot.

I don’t have a clue but I can say that the minimum delay hasn’t really changed much since Cheapbastard pre-XM days. It is more consistently close to the minimum for sure but that’s what I perceive.

I thought I saw somewhere the FF is AP is a partner with the Sentry producers. Maybe not.

Even though I have all of those functions on my experimental panel, I’m getting a Sentry for sure. It improves my backup capabilities and it will be nice having it all on my iPad as well. Great price point.

The FAA claims their transmission of ADS-B weather can be as much as 30 minutes delayed due to the nature of ADS-B multiplexing traffic and weather data together.

Not just the usual “few minutes” direct from a public NOAA derived source. Traffic takes priority over weather in ADS-B.

Maybe that’s the part you were unaware of? There’s added significant delay and buffering on the FAA side after reception from NOAA. It’s variable and built into the system.

I can get automated thunderstorm warnings from private sources that’ll predict their path and warn in minutes at a particular location.

ADS-B weather doesn’t work that way.

I've heard up to 20 minutes delay, however, XM uses a different network and they have similar delays as noted in the safety alert link below. Within that link, there are other links to incidents using XM. So two different delivery system have similar latency despite having two different network systems, to my eyes. I read your reply, it makes sense until I compare it to a product that doesn't deliver traffic information.

I believe there was an exclusive partnership between ForeFlight, Appaero (maker of Stratus), and Sporty’s when ADSB In was first introduced. That exclusivity agreement must of expired at this point. It is going to be fun to watch how things evolve over the next two years. Glad I didn’t purchase a 2 or 2S within the last six months. Almost did. My first generation Stratus has been working just fine for what I need. The new price points will probably convince me to purchase something new in the next 6-12 months.

I agree. One more each of AirVenture and Sun n Fun to go before the mandate happens. Could be some interesting solutions ready for sale by then.

I live in the heart of Silicon Valley, surrounded by Google, Facebook, Apple, Intel, Tesla, and Stanford University. On my daily commute I pass by countless pharmaceutical companies producing cancer drugs that I use to treat my patients. Is there something about products from California that concerns you?

Yes....I lived there for 35 years. Moving out is the best thing anyone can do unless they enjoy being a slave to the state.

Well, I'm happy that you found your new home. I think it probably raised the intelligence level in both states.

I'm from a flyover state, so I'm not smart enough to get that joke. Dadgum it!

He's calling me dumb because I called him out in another threat. A rather crafty quip, I must say.

You asked, we listened. Our new Stratus 3 is OPEN to the most popular flight apps, has new features, and is being introduced at a lower price. Stay tuned for the full announcement next week. The best just got better.⠀

LOL...

“We just got our butts kicked by half the price by a competitor. You noticed. Here’s a cheaper version of what we’ve been making a fortune on by using code from Stratux GitHub.”

Do you know of anything that cures Prop 65 warnings? :rofl:
