Flying with a Garmin GI 275 MFD 

Just announced... the GFC-500 is now approved for the G5's Saw it in a Garmin email earlier today!

@@sparkie951 Awesome!! Thank you John! That is good news 😊

Thanks, I would love to see the panel of your Baron when finished. What model is it? I flew 55’s and 58’s back in my corporate days, even a 58P for a while. You’ll like the 275s for sure.

@@dcheever777 I plan on doing a video and uploading it to YT... My old Audio Panel didn't like and audio recorders so I'm having to get the GMA345 as well so I can finally start creating flying videos

@@dcheever777 it is a 1973 B55

Thank you. I really enjoyed your video comparing the two, it inspired me to do an airborne comparison.

@@dcheever777 I'll be looking forward to it. I'm definitely going with the 275's.

@@quinnjim It’s up now. I mentioned you in the comments, hope that’s ok.

@@dcheever777 No problem. I'll check it out!

The problem with including the cost is it may (will) change. The best source of the instrument cost would be Garmin's website, I'll include a link and hope it works. Regarding installation, there are so many variables only dealer could give you a true estimate after looking at your plane. In my case the 275 was part of a bigger install job and certainly cost less than had it been a standalone installation. The price has gone up since I installed mine. I hope this will help: www.garmin.com/en-US/p/719027/pn/010-GI275-06

That’s a good question, I’m not sure which screens are accessible in that configuration. My guess is that they are limited, but a call to Garmin will tell you. I haven’t flown the AV-30, but don’t like the fact it has no magnetometer. In my opinion it’s a VFR instrument, the Garmin’s are both very capable IFR tools. Best of luck and happy new year.

Hey Paul. You should definitely talk with a Garmin dealer and get the correct configuration for your needs. Although the MFD does have an HSI display I don’t think it’s certified as a primary instrument. A dealer will steer you to the proper model.

That's a good question, I don't think there is a simple answer for everyone. I like the slightly larger screen size of the G5's and would not trade them for GI 275's, however I can also envision many installations where the 275 would be preferable. Instances of that might be not wanting to change the appearance of a vintage panel or not wanting to install analog gauges on a small panel. With the G5's airspeed and altitude are not primary, with the 275 they are. Another case would be integration with a third party autopilot that won't work with the G5. I'm sure you can find RU-vid videos of them installed as ADI and HSI that may help your decision. It won't be an easy one to make.

Hello Hiago. I fought with this issue for months after installation of the GI275s. Finally I had the latest firmware update put in ( which is probably not your problem if they are new, but check anyway) and tried a direct connection via the USB dongle. That finally worked. It seems like neither the Wi-Fi connection or pushing from the GTN works for the Terrain Database. Garmin tech support is nice, but they had no idea how to solve it. This was quite sometime ago, perhaps they know more now. Please let me know how you resolve it, I would be very interested to know.

@@dcheever777 thanks for your answer! So, I guess that Garmin still didn't figure how to solve this nowadays... Because just like you, I tried to push the Terrain Data from my GTN and also with the Wi-Fi connection. No success. The main reason must be the size, Terrain Database is too large compared to others. So it demands to upload and update via USB only. I will try to do that later on. I'll let you know if I succeeded or not, thanks again for the help!

You should talk with the nearest Garmin dealer and get an estimate. There are so many variables that any guess would most likely be way off.

@@dcheever777 thank you. As to the “why the HSI” I can see people utilizing it if it’s their only GI275 and having to fly an approach. Had the dual EIS finally installed….love it (have uploaded a video)

Yes they are. All LRU’s talk to each other on the CAN bus.

Hi David. If you want to do VOR/ILS approaches you need a GTN650XI instead of the GNC 355 unless you also have another NAV/COM. I highly recommend you set down with a CFII and your Garmin dealer to discuss your needs and options before making any decisions.

Hi Cap. Yes, the GTN does reflect whatever fuel status is showing on the EDM 830. I haven’t flown much lately, seems like there’s no place we want to go right now. Looking forward to getting back in the air soon.

It’s actually easier to see than I had imagined. You can check prices at any online supplier. This is an item Garmin doesn’t require a dealer install, an A&P can do it. One caveat though, be sure they are well versed in electronic installation, the CAN bus must absolutely be wired correctly. I’ve heard of intermittent problems when it isn’t.

It’s height above sea level as determined by the GPS, not barometric. The acronym is for Geometric/Geodetic Sea Level. I put it next to MSA for a quick reference, but didn’t find it useful and have since changed it.

nevermind, I it doesn't look like you have a nav2 only comm2.

You are correct Dan. It’s still a good question though. If there’s a second NAV I expect having the MFD set up to display it would be great. Honestly until after it was installed I had no idea that I would be able to use VOR on the 275 simultaneously with GPS on the G5 both from the GTN. Whew, that’s too many abbreviations in one sentence!
