I have recently frozen the SiriusXM account and on a recent flight I switched the weather source from SiriusXM to FIS-B (free). Passing by Beale AFB I did not see the TFR over that airport as I was expecting (it showed on my ForeFlight). Then I noticed the annunciation on the MFD top left of the screen, saying it was not available. Picture attached.

is there a setting I am missing?

thank you,

Yariv

Same here. As near as I can tell, the G1000 was designed before FIS-B and is incapable of displaying TFR's from that data source. It only can display from Sirius

What UAT device do you have that receives FIS-B?

I have been having the same problem with my GTX 345 connected to a GTN 650Xi. The GTN is receiving NOTAM-TFR, but the TFR with a graphic do not display on the map. I’ve been working with an FAA contractor trying to figure this out. Garmin has been no help whatsoever. Still, I would report this to them as they only seem to take issues seriously when complaints reach a certain threshold. Right now, I suspect there is an issue in decoding the FIS-B graphic information. If you have a GTX, that might point to the issue being in that unit.

You cannot really use ForeFlight to compare FIS-B with the Garmin equipment in flight if the iPad had been connected to the Internet recently because ForeFlight gets TFR data from its server over the internet and caches it on the iPad. In flight, there is mo way to know if what you are seeing is current ADS-B data or cached and there is no way to clear the cache. I submitted an enhancement request to add a means to clear the cache.

The G1000 uses the GTX-345. My Foreflight is connected to Stratus 2.

I believe it is a software issue with Garmin. I can display TFR's on my iPad with Garmin Pilot using the GTX-345 via bluetooth. However when you consider the G1000 MFD was not designed with FIS-B in mind until later updates I believe they left the feature out for whatever reason. The Sirius overlay is different, and much more complex. I live in the South so I keep my Sirius subscription because of the quicker Nexrad updates. I only discovered the anomaly when my GDL-69A quit working and I switched for FIS-B while it was being repaired.

I asked Garmin if Pilot caches data like ForeFlight but never got an answer.

My last G1000 experience was before datalink weather, so I’m not current on that. Is there a way to display the Current Reports List and NOTAM text on the MFD?

I’m not sure what the G1000 “TFR N/A” annunciation means. It seems similar to the “TFR: No Data” annunciation on the GTN map which appears to mean that no graphical TFRs are available for display even though the text of the graphical TFRs may have been received. The FAA contract engineer explained to me that the graphical data is sent separately from the text. So there is probably a decoding problem somewhere in rendering the graphic.

What software level do you have on your G1000?  401.XX

Yes, you can display text,  you just cannot display graphically. I agree it is a decoding problem. Simple way to fix, Sirius.

401.34

I think the latest version is 401.36.

I asked the mechanic to upgrade it during the last annual but he didn't think it was really needed and told me it would take a long time to do it.

Another weird tfr display issue…. 
the ipad has not been on internet for a week and I didn’t turn it on until airborne, so that “should” only be adsb display on it from the gtx345.  The g1000 has gtx345 and xm (not sure if xm has tfr info?).  If you look close, there’s an active tfr on the ipad that doesn’t show on the g1000 and one on the g1000 that doesn’t show on the ipad?!  Be careful out there assuming everything is showing!

(sorry they aren’t oriented the same. Also the south one near Yakima, isn’t on the g1000 even if you scroll further south)

It's kind of a mess. I haven't flown a G1000 with ADS-B In, so I don't know what peculiarities it may have. But I have noticed some interesting things with ForeFlight and the GTX 345/ GTN/ G3X combo:

1. ForeFlight when connected to the internet seems very reliable in depicting TFRs from the official source: tfr.faa.gov (ADS-B uses the same database). "Stadium" TFRs for major sporting events are not included in the FAA database, but ForeFlight uses other data to depict these also. ForeFlight caches whatever it receives and so if you connect it to the internet before flight, it will show what was then-current even if it receives no ADS-B data. If it is receiving ADS-B data, it ignores the internet data.

2. On ADS-B, textual NOTAMS (including NOTAM-TFR) are usually received fairly quickly, but the graphics are transmitted separately and are more data intensive and may not show up for some time on the GTN map.

3. Garmin claims that the original problem I reported (some TFRs not being depicted) has been fixed by software releases for the GTN and GTX 345 earlier this year. The problem was that if a TFR was active for more than one day, the software only depicted it on the first day. However, there was recently a VIP TFR in the Seattle area that was depicted on the GTN but not the G3X. I reported this to Garmin and so far they have no idea why.

So, it's a good idea to always get a weather briefing and check the TFRs because the ADS-B information is sometimes missing some.

I have an issue with TFRs on my system.  G3X, GTN Xi, GTX-345R.

NO TFRs on the G3X or GTN-750Xi ( I did not check the 650Xi).

I have SXM, but it is not working well due to antenna position and low signal strength (may be fixed on Friday).
