Flying with a Garmin GI 275
The AI version of the gi 275 only has that one page
did you wait to the 4 min mark? goes to a video
Excellent analysis and discussion. Very helpful.
Nice video... I had a G5 and swapped if for a 275 during a panel update. Integrated WiFi simplifies updates and if not mistaken will facilitate syncing databases with other Garmin products.... Plus I think it looks cool.
I've got 275 ADI, HSI, EI. I love it. I keep my ipad on my knee thinking i'm going to use it but end up just closing it. I only really use the iPad for preflight prep and the scratch pad now.
Can you post a link to a pic of your panel..?
Thanks for sharing, Very helpful video! Answered some questions
I have a pair of G5's with an Avidyne IFD440 Nav/Com. I love the G5's. You get both RNAV and ILS glide slopes on the G5 HSI. I did keep my old CDI hooked to my old KS 165 as a back up, which I've never had to use. 95% of the time I do RNAV approaches. The one thing I'd check before committing is install cost, install a lot of times costs as much or more than the unit themselves. The other advantage of the 275 is being newer I'd expect it to be supported by Garmin longer, can be a big deal for software updates.
Good info. Thanks!
We are installing 2 GI275's in our TB10. It pairs up nicely with our 530W. I am looking forward to it. Just dropped the plane off yesterday to get them installed. Looking at 3 weeks turn around time
Great unit. You have to continually update them, which kind of surprised me. Probably worth it for the internal navigation information it gives you
Only just started researching but part of the genesis of gi275 seems to have been the ability to link with legacy autopilots
Another big advantage is - as you mentioned - when coupled with correct navigator the ability to shoot approaches with full digital cockpit, also brings gps lpv to the party
Install - round peg in a round hole for gi275
One can get rid of vacuum completely as well as ability to bring digital EM display
A LOT of functionality really for the gi275 so as per usual mission is key to decision
If you lose a 6-in-1 you lose everything. Don’t discount the value of a six pack. They got us this far.
Love my GI275’s. I use the synthetic vision too.
I battled with the same decision. My avionics shop was most helpful in giving me all the information on the differences between the two and what it would take to make them both work with my existing avionics. It was more money at the end of the day but i went with the 275. Nothing wrong with the G5, but the 275 is a state of the art unit able to do many things and it will get many more software updates going forward. It's much more complicated than just comparing unit prices. There is installation differences, how things connect, extra components required etc. My 2 cents worth.
Very true. I'm leaning that way.
@@quinnjim I installed the 275 as a back-up AI. Garmin has announced further software changes. In the near future the 9 screens will be available for use as well with the G500/600 PFD/MFD. If the G500/600 loses power, the 275 will automatically switch back to AI mode. I'm thrilled with my decision to go with the 275.
@@rfriesen1644 Good to know!
Popper and I were just talking about you and this exact subject...we are all looking into these for our respective aircraft...
Popper is trouble. He loves it when other people spend money on their airplanes!
They were running a special pricing on the 275 when you buy two. I don’t know if they still have that in effect.
Since I'm sitting at my computer spending your money....the 275 is a no brainer. Newer tech is newer tech; quicker processor, lots more display info... The G5 looks tacked on while the 275 will look gorgeous on the panel. I feel that you are also leaning on the 275 too, may be just need a little nudge to justify haha! I only dream sometimes by sticking my cell phone on my panel with an AH app running, pretending I am flying something fancy. You are living my dream!
If I get the G-5's I might be left wondering if I made the right decision passing on the newer technology and added functionality. I think buying the two 275's would leave me with no regrets other than missing the extra money in the bank!
I battled the aging eyes comment when choosing what to upgrade for my 172. I went with the larger screen gtn750xi over the 650 for that exact reason. Get rid of the iPad and now the dual G5’s work seamlessly for any approach (rnav, ils, vor, dme).Also your radio is older and takes up a lot of space. Consider replacing it as it may go out in the future. I find all the whiz bang features on the small instruments marketing fluff. During actual flight a quick scan is all you have to get the necessary information and the dual G5’s present that in a clean easy to use format. If you are getting into the panel, my suggestion is to do it once, and do everything so it is in the shop once, then you can go and fly and enjoy !! It’s just money.... but you won’t regret the bigger screen.
Finally someone that went big with the avionics in their 172. My 172 is in the shop now getting a 750xi, two G5's and some other stuff.
I'm 39 and I prefer bigger is better, because why make things harder. Especially in the event of an emergency, with my family on board... 750 and G5's all day.
Thx for making this. While I don't see an upgrade from my steam gauges in the near future...I've certainly thought about this comparison. The 275s are obviously the better unit, I'm still not convinced the added cost is worth it. I say that because, from what I've heard, the labor price will be much higher for the 275s..when using for ADI + HSI. Somebody please correct me if I'm wrong.
Thanks for your input
G5 has no noticeable lag in the airplane. I’ve got a GTN650 wired in to the G5 HSI and the G5 attitude indicator. CDI and glideslope pops up on the attitude indicator when you’ve got em dialed in. Looks damn good, I prefer square to round. Should have had the avionics shop flush Mount em. Plays nicely with the STEC 60-2. Not worth the extra cash for the GI275 IMO - save your $$$ to put toward a new navigator or a GFC500.
Question : On the new GI275 do you still need the standby/backup as you do for the G5 ????
David Rendon I do not think you do for it. The GI275 is so small though it would be nice to have the turn coordinator as a backup. Even on the G5, I still find myself referencing the actual turn coordinator. Also, TC was required to stay in place for the autopilot anyway.
Thank you for this comparison, I was thinking the exact same thing about the size of the G5 looking 'bigger', simply due to the square corners. I'll be going with the dual GI275 now
Me too!
Thank you for the info!
This is a great video, more so, I had the same question as a theoretical what if I had my own plane and spec out a moderate panel upgrade. GI 275 has great features but the same duplicated info on the foreflight. However, I assume that the GI 275 is more upgradable than the G5.
I am going with a 275 in my panel for backup to the g500txi. I think the 275 will get more software updates. 275 is just newer stuff.
I forgot another issue. The compass rose on the 275 in HSI mode is cut off at the bottom to fit the Heading and Course digital display in soft buttons. Unfortunately, they block the portion of the directional ring where the reciprocal heading would be. So you aren't able to determine your reciprocal heading by just looking at the display. The G-5 has a smaller directional ring that is not blocked by anything, so the reciprocal heading is small, but readable.
Unless I'm missing something, can't you just look at your heading and add or subtract 180 to get the reciprocal? Maybe I'm extra good at math and don't know it, but that isn't hard to do in my head.
@@davidtroup it's not a question of hard or easy, but of bandwidth. It takes some bandwidth for headings >180 degrees, but not that much. It takes more for those
@@barrysperonello5822 You're right, of course, that when workload is high, having to do an unnecessary mental calculation (even a simple one) just adds to the stress. Too bad Garmin couldn't have come up with a way to display the reciprocal on the GI-275.
Was just talking about this again today. I actually already have a G5 HSI, which I put in a few years ago when my mechanical HSI needed overhauled. I think if I didn’t have that already I would go with the 275. It’s not that much more money in the big picture. That being said, I do think most of the extra features, the screen is too small to really be the go to. It’s there when you need it I guess... but will you even use it enough to be familiar with what’s there and how to access it when you’re in a pinch? I don’t know. I have two GTN 650’s, and I find myself not using MANY of the features just because the screen is small... and that’s a lot more real estate than the 275. I will say the flight path vector would be nice, and I think everything you need for that to be useful is right there in the center anyway, so not a big deal it’s small. Just “put the thing on the thing” and you’ve got it nailed. Anyway, it only makes sense for me to do the G5 as it’s a very simple install, whereas to go 275 would mean gutting what’s there and basically starting over. I guess I’ll hope someday they will offer a plug and play G5 upgrade with a touch screen and faster processors like the 275... Looking forward to your 182 refurb content. I love watching other people spend stupid money. Makes me feel not as nuts when I do it haha! It’s fun though, and you only live once.
They have a deal right now where the synthetic vision is only $500 (instead of the usual $1,000). It might be worth it for that.
Dual G5’s with GAD 29B, GAD 13 and hooked up to GTN 750 and old Century IIB autopilot. Also have iPad mini on the yoke which is connected to GTN and GTX 345. Love the G5’s!!!!! They give me everything I need and more, easy to read as depictions are simple and less cluttered. Friend got 275s as he always has better kit - was jealous at first, but after flying with him, I find that most of the functionality doesn’t get used in his cockpit since he has a good navigator (430) and an MFD. they are small for what they display, but man they can do a lot. You have to look at what you need, and what other instrument you already have. Sometimes “too much” can cause problems from a human factors point of view. That being said, if you have limited panel space and are looking to obtain these to truly improve situational awareness cause of other old equipment (old radios, small gps screens, etc), then the 275’s are a better way to go for sure.
The main thing I think I'd use is the moving map combined with the HSI. I think seeing the fix coming up on the small map may give me some additional situational awareness without having to look over at my iPad. That is my setup at work on the 737. I'm used to seeing a map in my main scan. This map is so small that I'm not convinced of its usefulness.
@@quinnjim I could see that being useful - especially if you have a similar scan already with your EFIS in the 737. I am going from steam gauges, but with my cockpit, the GTN750 is just a little to the right (Cessna center stack) so I can quickly see my progress. I'll be honest, I tend to use the iPad only for my weather (METAR, TAF, etc), approach plates and other ancillary stuff. Good luck on your decision!
@@jeffreygoyer7760 Thanks Jeffrey! Lots of good points.
I have a dual G5 set up now and am moving to 3 GI 275s as they work better with the STEC 3100 that I am installing in April. Keep in mind the 275 replaces the whole 6 pack, the G5 does not.
Good point.
Swapped out an old Sandel 3308 for the G5 HSI. Great replacement. The screen is smaller than I thought.
I remember when the 3308 was cutting edge technology! I'm leaning towards the 275 so I'm not outdated as quickly.
In the experimental world I think G5s make sense. Certified world probably suits the 275 -- this is no doubt how Garmin positioned these products. Good video.
I think you have a good point there.
To me it depends on if you plan on keeping the 182. If it’s your dream plane, the 275. If its a goner, the G5. It’s fun spending your money!
I need to keep it for at least 3 years. After that, I can't think of a good reason I'll sell it. It seems to do everything I want. I'd still like to have an RV-7 or 14 someday.
@@quinnjim- One question, what is the longest you have ever keep any airplane? Thanks for the reply.
@@thesearcherman6652 I kept my Cherokee for 3.5 years. That was the longest.
I just installed 275s in my 182. The cost in savings for installation on the 275 pretty much makes up the difference in purchase price. I absolutely love the 275s, both in functionality and looks on my panel.
I was under the impression that the 275 install is actually much more involved than that G5 install. How much labor did your 2 275s take? I've heard to expect 40 hours.
@@Wolficorntv My estimate is about 40 hours for the 275's, a new 345 audio panel and the GNC 355 NAV/COM

Club just installed 2 G5s. We have the old King 155 radios. Hindsight being 20/20 board now says should have gone with the dual 275. Main reasons: ILS on the HSI and our KAP 140 cant do vertical guidance LPV from our Garmin GPS 175.
Good to know.
Could you go with a G3X and a G5, both with ADHRS (versus 2 G5’s or 275s). That would solve the “tiny display” problem, allow you to fly off the G3X and have the G5 as a completely redundant (elect source, ADHRS and batt backup) IFR backup. It might take more panel work, but now’s the time.
I would love to see how that option compares.
@@thomasgross2841
I would as well
Garmin is currently running a promotion if you buy two GI 275s. So if you price out two G5s with magnetometer, the OAT, and the GPSS vs two GI 275s with the same options (some of which are included) the price isn't that much different. You also get wireless connectivity with the GI 275 which you don't get with the G5. If you hook up the optional VFR GPS antenna you get a backup VFR GPS in case your IFR GPS fails.
My shop had a "bundle" deal that saved $400 plus got the synthetic vision for $500 (instead of $1,000). It was still $2,300 more for the 275 ($2,800 more if I went with the synthetic vision). Where did you see the deal where the price wasn't that different??
@@quinnjim Sarasota Avionics is one of the few places that has the bundle prices online. 2 G5's with GAD 13, GDP 59, GMU 11, and GAD 29B = $6964. The two GI 275 bundle with ADAHRS and A/P interface includes the GAD 13, GDP 59, GMU 11 and you don't need the GAD 29B for $7429. The GI 275 will also wirelessly transfer flight plans to Foreflight or Garmin Pilot provided you have a GPS 175, GNC 355 or GNX 375. That's a $1300 option with the G5 for the Flightstream card.
I have a pair of G5’s in my Comanche.I’ve loved them over the last couple years. The 275 is nice but if you don’t need the interface with legacy Nav radios, go with G5’s. Put the $2500 savings towards 700gals of 100LL.
If your renovating a 182 panel like me I went with a single G5 as backup, mainly because the Garmin autopilot needed the G5 AHRS input. I don't think the 275 unit is large enough to sub for a PFD, just can't see it well enough. But I junked the entire 182 panel and put in a whole new Garmin system. If your thinking about adding a Garmin autopilot in the future be sure the 275 supports it.
It took a bit but now I fly an ils and only look at the 275 pfd. It has 100% of what you need
Thanks for Sharing, Great info.. I am getting ready to purchase a plane and working on an Avionics Upgrade plan. This video is very instrumental. thanks for sharing. Also, I just subscribed to your channel, Will be checking out a lot more of your info.
Thanks! My upgrades are all complete. I’m hoping to do a video of my final avionics setup soon.
Can I ask what you ended up going with? I am working on this exact same project with a Cherokee 180 that I just purchased. I am considering the 2 G5's or GI 275's to update the panel and get rid of the vacuum system as I complete my PPL and then I want to add a GNX 355 to continue on with IFR training.
I went with the 275’s. I added a Garmin 345 audio panel and a GNC 355 NAV/COM. I really like this setup, but the G-5’s are a great way to go as well. The 275’s have a better display with multiple screens (which is nice). They also have a navigation database built in, so you can navigate via GPS even if the 355 fails. I’ve flown the G-5 setup a LOT lately while preparing my buddy for his instrument rating. They work great too.
@@quinnjim thank you. I actually ordered the G5's today. Seemed more appropriate for the age and value of my Cherokee 180. That will give me better instrumentation through my PPL. Then I plan on going with the same 345 audio panel and 355 unless I decide to update my transponder and then I will go with the GNX 375 and new GTR 225 comm with the new audio panel.
I came close to installing 2, 275's last summer until I read the manual and found it takes one hard button push and IIRC 5 soft (screen) button pushes to change the HSI from Nav mode to heading mode. Same to go back. Couldn't imagine having to do that in turbulent IMC. Garmin acknowledged the issue and said they were working on a panel button to toggle between the two, and they would contact me when it was approved. Nothing yet.
I haven't heard of that being much of an issue. Most guys just turn the knob between the screens and have plenty of information.
@@quinnjim I wasn't referring to changing the screen appearance, but to changing the mode of interacting with an autopilot when using GI-275's directional guidance to control the autopilot. Consider being on an IFR flight plan enroute with navigation controlled by the GPS and the autopilot being driven by GPS roll steering (i.e., the system is in Navigation mode and is following directional signals from the GPS to keep you on course). As you get close to the destination the controller gives you a vector (i.e., heading) to fly as the beginning of vectors to final. To continue using the autopilot you need to switch the GI-275's from following the signal from the GPS to following the heading bug you set on the HSI (i.e., Heading Mode). To make that change you have to press the main button, and then burrow down into the menu system using several soft buttons until you can change to Heading mode. Then, as you get to the final approach course the controller gives you a last vector to intercept the approach course and clears you to fly the approach once you are established on the final approach course. That means you have to return to Navigation mode with the GPS controlling direction. Another set of a hard button plus several soft buttons to make that change. In IMC and turbulence (hoping that a bump doesn't cause your finger to brush against the screen and make a wrong menu selection).
Then you have to go missed because you don't break out of the clouds in time. And as you're trying to reconfigure the airplane and transition from descent to climb, the controller gives you a heading to fly. You either have to repeat the button pushing, or, decide to forego the autopilot and be forced to hand fly the missed approach.
@@barrysperonello5822 I see the problem now. I can't believe Garmin makes it so hard to do something that you will be doing on most flights! Lucky for me I don't have an auto pilot! Maybe by next year they'll figure it out.
Just installing 2 G5s in our C182. 1 as a backup to a G3X, the other one on the right side should there be a pilot on the RH seat.
Had an Aspen before, loved it, however the Aspen does not work with the GFC 500 we‘re installing as well, so we went for all-G...
I considered Aspen too. Keeping everything Garmin should guarantee that all the components work well together (hopefully). I'd like to do a GFC 500 next year (although I may go with the Tru Track).
MrMono, I’m considering doing a complete panel upgrade in my Cardinal. I’d like to get a G3X instead of 2 G5’s. I believe the G3X requires a G5 installation as a back up for attitude. Do you know if the Garmin GI 275 can be installed as the backup instead of the G5? And can the 275 drive a GFC-500 autopilot (as a backup to the G3X)?
@@cessna177flyer3 I flew 177 before the family-van (182), my wife and I loved it...
It is my understanding that you basically could keep your vacuum gauges as a backup. If you want to get rid of the vacuum system, you can take a GI 275. However, I don't see any advantage over the G5, as you would use it only as a, well..., backup. I'd rather save the extra money, or even better, spend it on something else;-)...
Anyway, both G5 and GI 275 seem to work as a backup for the G3X with the GFC 500.
@@MrMonoTracer thanks for the reply. I definitely want to get rid of my vacuum system. I currently have a basic 6-pack and an old Northstar M3 GPS that I am thinking of replacing with a Garmin 355 (a $5000 savings over a GTN 650). I’ll keep one of my KX-155s for ILS capability (and as a second radio). I’d like to remove both of my mechanical “windshield wiper” CDIs but the G5 won’t play with the KX-155 to displace loc/gs. The 295 will. So if Garmin will allow the 295 to serve as a G3X backup, I can also eliminate both mechanic CDIs. Oh, and I want the GFC 500 autopilot as well.
After seeing them side by side I went with the 275. It’s like a Tandy computer vs an uhd tv
The 275 is also little less labor as it fits a standard hole.
You don’t get all 9 screens. I ai mode you only get ai screen. Dg mode you only get ai, hsi, mfd screen.
Not only do you see taxi diagrams in mfd mode you see traffic on top of it on the 275.
275 will also drive more autopilot.
I’ve also flown behind the g5 but by comparison it is very pixilated and slow.
Thanks for the information, Robert!
This is funny timing. Chris Palmer is currently getting his plane's avionics upgraded and is mulling over these two units.
I'll go check that out!
Hi, I have some thought on your dilemma. I just had to go through that hurdle with my panel upgrade (currently in progress) and at the end of the day, I chose two G5's. In my personal opinion, there is little (if anything) gained in the 275's unless you're planning to interface them with GTX in/out, GTN WAAS navigators. I currently have a GNS430A in my cherokee 140, and it's currently getting a gtx345 and a pair of G5's. Another thing that helped convince me is there seems to be some intermittent bugs happening with the 275. Now, that may simply be an installation error, but it could also be a manufacturing error. Regardless, I chose the G5; not only because of the price difference, but because it just fits well with the rest of my avionics package. That being said, I do plan to add a GI275 MFD in place of the NAV1 CDI (which is about to be emptied because the G5 STC requires the CDI be disconnected from the 430 if interfacing with the G5 - Which I am) and interface it with the GTX345 so that I can have traffic and weather and effectively eliminate the IPAD. Those are my thoughts. Good luck!
Thanks, Nick. Great input. I'm leaning towards the GI 275 just to have the "latest and greatest", but I really don't think they will do much more for me than what a G-5 will.
@@quinnjim at the end of the day, I think you’ll love them. I’m actually doing my own install (with oversight of course) and I looked into how involved either installation would be. The 275 should be a fairly simple installation. If you’re interfacing with an AP or a NAV, maybe a bit more involved but overall i would expect installation costs to be similar to a G5 setup.

Thanks for the information. The Twin Comanche is on my "short list" for the next airplane I buy.
You can connect a legacy analog NAV/COM such as a KX-155 to a 275 HSI as long as it is not an HSI/Standby ADI. You cannot connect an analog device to a 275 ADI or Standby ADI because of lightning protection. If you want to get rid of your six-pack then you would need a 275 ADAHRS (+AP) along with an ADAHRS configured as either an MFD/Standby ADI or an HSI/Standby ADI and neither of those could be connected to a KX-155. You would need to purchase an additional 275 configured as an HSI only or get the Garmin CDI digital display or keep the original CDI display.
If you want to see the 275’s in action you can look up my videos on them.
Chris Koppel
Thanks, Chris. I've already watched your videos. Someone else mentioned about lightning protection being an issue. I guess I'll just keep my current NAV/COM for the ILS. It can be my #2 radio. I don't see myself shooting many ILS approaches since GPS is available just about everywhere and it gives a better signal.
What is supplying the traffic info to the 355? Will a sentry send adsb data to the 355
The Garmin transponder is responsible for ADSB. I have no idea about the sentry.
The cost to install a 275 HSI is 6K. I wonder what the G5 HSI would cost ?
If you have the money I'd say the newer unit for its features and backward compatibility. I do prefer the square over round though
For some reason the square display is more pleasing to me as well.
I went for the G5 for this exact reason, square looks way... better, the 275 looks just like an old steam gage. Synthetic vision in such a small screen is more clutter than function. Plus, as mentioned in the video, all the magic in screens are now for the iPad. I am more than happy with my dual G5. And, and don't understand that argument about needing an old needle for approaches, I can shoot both ILS or GPS with the G5
I’ve been wondering myself. Been leaning toward 275. But wondering what the cost for install is for both as well? I haven’t gotten far in my research. Thanks.
For two GI-275s, around $16k all-in (including the $900 synthetic vision option), give or take a couple thousand depending on your local area.

@@daveluck6578 thanks for chiming in. The extra info is much appreciated.
We have the ADI and HSI 275s with a GTN650. They are great but do take some time to get used to. As a reference point we had minimal glass panel time. In our plane you need to fly 1-2 degrees up to stay level. You cannot adjust "level" like on an analog AI. The situational awareness when flying in the clouds in the mountains with the synthetic vision is great. We have not flown the G5 but our avionics shop said we would have had to keep our old vacuum system to drive our Century 2000 autopilot. That seemed to defeat the point of going digital so for us the 275s were it. We were transitioning from older analog instruments so I will point out a few features on the 275s that we like. (1) It automatically sequences for flight plan direction changes and with the autopilot engaged will fly the flight plan and also fly heading changes on an approach. (2) You can select your assigned altitude and/or approach minimums, within 1000' the altitude will blink white and within 200' it beeps. This is a nice back up if workload suddenly increases. (3) The HSI shows the Fix, Distance and Time. This is a nice back up for what is next on an approach. We do not fly a lot at night but the back up batteries give you plenty of margin should you have an electrical failure. Both the ADI and HSI can show a lot of information in a small space but after a few hours you narrow down what is important to you. Hopefully this is helpful.
Great information! You can have the shop adjust the pitch where it shows level pitch properly. My friend with the 275 AND my buddy with G-5’s both had to go back for pitch adjustments.
@@quinnjim Interesting our shop says they cannot adjust them. We were the second install for them so I will double check with them again.
@@frankduncan1323 I've seen them adjusted by the shop. The G-5 can be adjusted on the unit itself, but it's not recommended. The shop is supposed to calibrate the units properly.
@@quinnjim Our shop says it is not legal to adjust them other than per the guidelines of the install manual.
@@frankduncan1323 That is correct. The shop is supposed to calibrate them (according to the install manual) so that they show level in level flight. If they don't know how to do that...find another shop. My friend was showing 4 degrees up in level flight. That obviously wasn't right, so he brought it back and they fixed it.
Very cool side by side. Is install equivalent or more for the 275?
The install was the same.
The 275 is direct fit. The g5 usually requires widening the holes so the two units don’t touch
I love my G5 paired with a area 660 and an Ipad.
Do the dual G5’s
does anyone know if Gi275 plays with Avidyne IFD navigators?
I have 4x 275, ADI, HSI, EIS, and MFD. like Tyler I started flying with my iPad but now I don’t use my iPad in flight anymore. I do use ForeFlight to fill the FPL on the GNX375. I have flown with the G5’s too, but the 275 is worth the difference in my opinion.
I agree with you. I like the engine monitor function too. Maybe next year.
Isn't the cost for 4x275 into about what the G3 panel upgrade would be?
I like the 275 but obviously not the cost. I do like how they look more traditional/old school if you’re looking for that. I like the tech and extra features as well. I guess if you’re looking for longevity the faster response (guessing due to better processors) might be a consideration). I’m leaning toward the 275s for that. But for the price and simplicity I like the G5. Tough choice.
I keep going back and forth. I could easily make due with the G-5.
One other thing to consider regarding 275 vs G5 is that while the G5 slots into a standard instrument hole, the square form factor may require a slight panel modification (like with the Cherokee plastic overlay), where as the 275 is truly a drop-in (as far as the panel goes).
If one is not a strictly a Garmin fan, the Aspen E5 makes a lot of sense over the G5. Much larger, brighter and clearer screen with excellent interfacing options including legacy Nav radios. Build quality feels like a real piece of avionics instead of plastic G5. There is even an upgrade path to full synthetic vision. I think it’s a no brainer.. all the features for the price of G5s.
I'll look in to that. My appointment isn't until June, so I have some time. I am definitely getting the GNC 355 NAV/COM, so I figured buying Garmin instruments would guarantee a smooth installation.
We also considered the E5, but I liked the redundancy of the two 275s (or G5s, since that was our other choice). The E5 also has a couple fewer features, unless you go with the Pro, but oddly then you can no longer remove the vacuum system unless you have two Pros. It would also change the way the Stec 55X works when following GPSS. But honestly I think all three are worth considering, and it comes down to which features you consider "must have", and which interface you like better. I preferred the 275 over the G5 because it has the same user interface logic as the GTN650 that we already had installed.
@@quinnjim Am I missing something? If you're getting gnc (nav/com) why would the g5 analog radio conflict even be an issue?
I just installed 2 x g5, gnc-255, gtn-750xi and a gi106b. Everything gets along well.
G5 should talk to gnc if that's what your plans are.
I'm taking delivery of my dual GI-275s tomorrow. I chose the GI-275's because they will work with my KFC200 autopilot. The G-5s would require me to change out the AP at substantial cost. I'll get back to you and let you know how it turns out. Thanks for the video!
Let me know how it turns out! My 275's are installed. The avionics shop is just finishing up my installation this week.
@@quinnjim The 275's have vibrant displays. But, they need adjustments, the ball is way off center and the AI display is 7.5 degrees nose down in flight. We are making an appointment to get that fixed. The guy that makes the panel plugs was out for a week so I have to go back at some point and have that fixed as well. I'm pretty happy with the 275's I think it's a cleaner look than the G5's on the panel. But the fact that I could keep my autopilot was the selling point!
@@glidslop I helped pick up a plane with a new 275 and another one with a G-5. BOTH had pitch way out of whack. Not sure why avionics shops don't calibrate them correctly. Seems pretty important.
@@quinnjim The test pilot is supposed to meet me today to adjust it some more. I would have thought the avionics guy would do that but........the pilot is a BPPP (Bonanza PPP)guy and knows his stuff. I'll let you know how it turns out if we don't get weathered out today.
@@quinnjim So the Bo is back and a BPPP pilot came and adjusted some settings in the "config" mode. It's still not right. On the ground the AI shows 7.5 degrees nose up. In level flight its still two degrees nose down and the ball is almost full scale deflection. I'll like the two 275s after the bugs are worked out.
The 275 is capable of showing a lot of different pages, but in a ADI+HSI configuration, the ADI only shows the ADI page, and the HSI only shows the ADI, HSI, and Enhanced HSI pages. If you want the other pages too (like dedicated traffic or weather pages), you either need a 3rd 275, or not have the 275s configured as primary instrumentation.
I don’t think that’s true. If you have the ADI configured with heading on the bottom of the display, you can have the 9 pages on the HSI. Another option is to keep your old heading indicator somewhere on the panel.
@@quinnjim That's how it works with our installation. The HSI is configured as a "Standby HSI", meaning it will automatically take over as an ADI if the primary ADI fails. I believe this is the setup required to also remove the vacuum system, which we did in our case. The 275 installation can get confusing because there are a lot of different ways to configure it, and depending on how it's configured, some features may or may not be available.
@@garyb.4834 My shop initially said that I needed to keep my vacuum system. They did some more research and concluded that the ADI has all you need. If either instrument has the ability to give attitude and heading information, they independently give the same information that BOTH instruments used to give. I need to look into it a little harder to make sure that the shop is correct!
@@quinnjim Supposedly Garmin includes an STC with the 275 to remove the vacuum system. In practice, the single 275 ADI is probably more reliable than the vacuum system, but I would want a dual setup anyway. We inadvertently proved the resiliency of the system when the avionics shop discovered Garmin had a problem with the latest software revision and both of the units reverted to ADI-only.
@@quinnjim if you do that you lose automatic reversion detection. So my hsi is configured as ai backup and only had 3 modes.
I can tell you did not have your coffee. Your hands are as steady as can be.
On the serious side however, if you have the panel space I would look for something with a larger display.
Thanks, interesting. Another point for the 275 is the autopilot. The G5 only supports new autopilot while the 275 can work with most traditional APs
I was just flying in my friends 1977 Arrow with the original auto pilot and 2 G-5’s. The auto pilot worked great. I had heard that G-5’s don’t work with older AP’s, but that isn’t always the case.
@@quinnjim the issue is that the g5 can’t provide attitude information to analog APs. Maybe he had another instrument that provided that on the panel, like a turn coordinator... I’m not sure what the classic Piper APs need as input. Our goal for a c182 is to get rid of all conventional gyro instruments and the suction system. That’s only possible with the GI275
@@michi795 His AP was for heading or GPS course only. He had an older Attitude Indicator still installed, so maybe that was helping out. We used the AP to track our course all day and it worked with the G-5 for that. I’m going with the 275’s and pulling my old vacuum system as well. I’m going with a modern AP next year.
@@quinnjim exactly, mode does not matter, it’s the attitude information where it requires another source. New AP: i’m doing the ifr training parially in a turbo arrow with the g5/gtn750/gfc500 combo. awesome thing, pretty much airliner level from the functionality perspective, just lacking the money ;)
Can you replace the six pack with GI 275?
Yes. I could have replaced all the instruments with the 2 GI-275's.
If you still have a steam panel, yank out the vac system and pop in two GI275s.
If you already upgraded the AI/DG to G5 (like me) then you're better off either leaving things as they are (as the G5s are great) or do a leapfrog upgrade to a G3X.
Maybe the right answer is one of each? The 275 for whatever needs a higher refresh rate, the G5 for the rest
I've already pulled the trigger on 2 GI-275's. I think the G-5's would have worked perfectly fine though.
Very Nice video, I'm working on something new, Video coming out soon.
Funny thing is I put the GI-275’s in my 182, but now I’m putting G-5’s in my RV-6A. The 275’s were nice, but Garmin charges you a LOT of money to keep them updated.
275 If affordable
Totally agree. The G 5 is enough. Every TH-cam one watches the pilots all have iPads with third party sat nav features. In Europe Sky Demon is enough for VFR pilots.. I personally think Garmin really has to relook their pricing.. No body disputes how good their equipment is. It’s just the third party is stuff out there far cheaper doing exactly the same..Sorry Garmin love your stuff but too expensive.
We will definitely be flying this plane IFR. I like the additional situational awareness the map on the HSI gives you. On the 737, I'm used to having that (although it's a larger display). They will probably discontinue the G-5 and bring the 275 price down eventually.
I prefer G5 is more clear and wider though might the color bait low resolution
I've flown both. The G-5 isn't really any bigger. It works great though.
@@quinnjim I like the shape of it. It is more comfortable to my eyes. During training my Cessna 172 had G5 and I really enjoyed it.
I've been flying the G5 for 4 yrs, paired with a GTN-650 and a G3X-T and recently started flying a 275/GTN 750. I don't like the 275 at all. My G3 and G5 would default in event of failure and control the autopilot. Your demo with roll response is invalid because you were rolling it faster than most GA planes will roll. I think you need to fly both side by side to make an accurate comparison. If you are talking install in a C-182, for sure you have a slow roll rate. I'm flying a fully aerobatic sport plane and the G5 is fine. You are correct the picture is brighter and color more vivid on the 275. Between the two, I like the G5.
I went with the GI-275 and kind or regretted it. I didn't realize that they require a paid subscription to keep them up to date (due to the internal map database). I sold that plane and now have a G3X with a G-5 backup. I don't think I'd get the GI-275 again. They don't add much and cost a LOT over the years to keep up to date.
Why not both?
Would one of each be an interesting solution?
That would look a little funny in the panel. I would probably work though. I like the synthetic vision that you get on both screens with the GI 275.
@@quinnjim so now it’s a question of how much not looking a little funny is worth to you 😊
At least now you have a third price point option
You put the round peg in the round hole and the square peg in the square hole 😂
Have you considered the uAvionix AV-30 -C EFIS?
I looked at it. Since it was their first try at this, I decided to go with a company that had a more solid track record. It looks like a good unit though.
Put two av30c in my plane and there is a BIG problem with the heading track. Major precession tried several things from some blogs ... not good enough..they know they have a problem but I feel it's my fault for believing in the product...solution garmin or anyone else....
I fly both units. G5 is best choice if it works for you. G5 is 70 percent cheaper. G5 screen is a noticeably bigger and better looking unit. GI 275 is better choice if you have to interface to an old autopilot but Garmin will make you pay even more money to unlock those extra interfaces. Only use GI275 is you have to.
G5 battery backup is 4 hours compared to GI275 has only 1 hour. So most avionics shops add second battery for each GI275 at cost of a little less than $1000 for two units. So all together GI275 cost 70 percent more than G5. Synthetic vision and moving maps on the GI275 are a gimmick because screen is too small to be effective.
It is also worth noting that Garmin offers a kit to flush mount the G5 if you want. GI275 has touch screen menus but again small screen size makes use kludgy. There is no noticeable difference in screen brilliance or processor lag between the two units. So when Garmin says GI275 has faster processor it is marketing only with no real word difference.
The screens are almost identical in size. The resolution on the GI-275 is much better. The fact that my lower screen has 9 pages as opposed to 1 is useful. The synthetic vision is a bit small, but it works. I like the flight path vector and the fact that airplanes flying by show up on my ADI. I went with the 275 and am very happy I did. I have flown behind the G-5's quite a bit this year. They are a solid unit, but are already outdated.
Stop! Take a moment and read this before you purchase. I own 2 avionics shops and have 37 years experience in avionics so you can trust what I’m saying is on the mark. Like it was said earlier, you will get only 3 pages on the GI-275 HSI and 1 on the ADI. Not 7. If you hear someone say ‘ But I have a GI-275 HSI and I get all 7 pages”. That may be true. The avionics shop can do that by mistake but you would be violating the STC making your airplane unairworthy and insurance wouldn’t be on the hook if you had an accident or incident. 7 pages are available if it is a backup to a G500TXi or G3X, or if it is a non backup map version. Here’s another one people just don’t know about and it’s a very big one. YOU CAN’T USE YOUR OLD NAV UNITS. Yes your heard that correctly. The old KX-155 and all the other old composite type nav units can’t be used even though they will work fine. Because of lightening protection issues, the old composite nav’s can’t be used as any primary. So you can’t replace the #1 or #2 nav CDI with a GI-275. You can only use it as a backup to an existing CDI which is useless. Now onto the synthetic vision. If you are an instrument rated pilot it is a must have. For reasons most people don’t even know. Get on the approach and put the flight path marker on the end of the runway and you shoot a perfect approach every time guaranteed. The glide slope and loc needles are frozen in the middle. Because it takes the wind into consideration there are no corrections need at all during the entire approach. It’s like flying on autopilot. The GI-275 is fantastic but know it’s capabilities before purchase. Hope this helps. -Avionics Guy
Thanks very much for the information. I guess keeping the old heading indicator in the panel (off to the side) would mean my lower 275 was a “backup” and I could get all the pages. It seems ridiculous since both 275’s have heading, attitude, airspeed and altitude.
@@quinnjim I understand (possibly incorrectly) That the ADI 275 is approved for primary Attitude, Airspeed, Altitude and Heading where the G5 is only certified for primary Attitude, this is the same issue withe the AV-30. Is this correct or am I mistaken?
How much is installation?
Thanks! It seems like this bandaid approach to upgrades is a waste of money. I’ll stick with what I’ve got (plus my ipad) for now. When it can no longer be repaired, I’ll replace the whole panel or get a different airplane.
For an experimental the G-5 is about HALF as expensive as the 275. So that makes the decision pretty easy for me at least.
I went with the GI-275's, but I wouldn't do it again. I now have a G3X with a G-5 backup. The 275's are nice, but you have to pay to keep them updated and the additional features aren't really worth it (to me).
@@quinnjim
You were able to get a G3x in your Grumman ? (Gulfstream American)
@@savagecubNever owned a Grumman. Put it in my RV-6.
Actually have seen a non certified hookup of a legacy nav radio KX155 working perfectly fine with the G5, I believe this is just Garmin milking people to grab one of their newer nav units....typical
That sounds like something Garmin would do!
The G5 has a 4 hour battery.... That is huge!!!
The GI-275 also has a battery. You don't need 4 hours. If you've lost your aircraft battery and your alternator, you will usually land at the nearest suitable airport. I do like the fact that I will have instruments after a total electrical failure. Both units have that feature.
I think the 275 gives a much cleaner looking panel
They definitely fit in the panel better.
Check dynon
the G-5 looks more user-friendly in terms of functionality display
The display is very plain. You can’t really change anything. Just a glass representation of traditional instruments.
I am still shocked that this stuff is so expensive and has crappy screens. The expensive part is the stuff inside and to certify the whole system. Screens cost nothing. Why don’t they offer a G1000 like screen? I know a whole G1000 system costs $370k - but just add a bigger screen to the 275 and many people would be more that happy.
The 275 can't be bigger. It's designed to fit in to an existing panel. If you want bigger, get the G3X. At that point, you have to cut a new panel and replace a lot of stuff though. I'm getting ready to put either a G3X or G-5's in my Vans RV-6A. Still trying to decide how big I want the project to be.
Here is a Garmin introduction th-cam.com/video/-p4iwgBBHPo/w-d-xo.html
To me, it’s a lot more $$ for not much more function. I’d rather add a third G5.
I went with the 275. Much better functionality (like 9 screens on the HSI instead of 1). Synthetic vision is nice and the screens are much better. The ARE more expensive.
I have a 185 with two G5’s (with wind/OAT/TAS) and a GMU 11 for slaved heading, a 530W, a 430W (GPS/nav com redundancy), a 345 1090 in/out, a GFC 500, Flight Stream so the iPad talks to the 530 (the twisty/pushy is minimized). I also have an iPad Mini with ForeFlight on the yolk. A dual cue is utilized on the PFD/AI and now with FD capability due to the GFC 500.
This setup provides redundancy and a four hour battery backup on the G5’s (removed vacuum system). It also provides essentially everything the newer units provide, but with less lipstick and makeup. I’m old, the plane is old, but the two of us are still more than capable as equipped.
One of the best things about owning your own airplane is that there are no fingerprints on the flight instruments. Because of that, I never liked touch screen equipment. It’s also a pain in turbulence. I tolerate the touchscreen iPad for the capability and functionality it offers. Life is a compromise.
The “old” G5’s are fine. The 275’s are too cluttered (especially with the fingerprints) for my taste and I can do the same stuff as the flat screen crowd with probably more redundancy for failure.
BGRS, B2E, B2C2D2 capable.
It’s always nice to have choices to accommodate everyone’s preferences, though.
Sounds like a solid setup. Having flown behind both, I prefer the 275. The G-5 is basically functional, but missing all the features of the 275. Either gets the job done.
by the time you buy two of those you are in G3x territory. Those displays are too small.
The problem is that one G3X is not enough to be legal. You would still need a backup G-5 or GI-275. You also have to completely redo the panel (which is a major expense). The G3X is a LOT more expensive. I’ve flown with these instruments and they are plenty big. Actually, the outside portion of the G3X (and even the G-1000) are pretty useless. Just extra sky and ground. The part you need to fly is in the middle (and about the same size as two GI-275’s).
@@quinnjim 1. Keep your AI and DG, just move to the side. The requirement is you have a backup AI/DG. 2. GI-275s are $3995 and you need two of them to equal a G3X, so $7990 vs. $8495 for a G3X. I won't debate the last point, but its staring at a watch vs a TV screen. To your next point a panel rip will increase costs without a doubt, how much depends on your installer. In my case I wanted to redo the panel in any case.
I did g500 txi and G5 as a backup, needed to drive the GFC 500. I would have gone G3X if I could, it was not available, and that would have meant keeping the AI/DG, which I find acceptable. I kept all the instruments I could. I actually like the mix of old and new tech:
drive.google.com/file/d/1fbFw4AYhdEx5vX8jhMQOsgWUUZ7-YySL/view
G275 toooo much information..
You can turn off a lot of the features so it shows about the same information as the G5. But even with it all on, it's not as busy as you might think. But even though the screen space is about the same, the G5's square display appears bigger, even though it isn't.
G-5. Why waste space? And the tapes look better, with bigger and clearer, easier to read numbers. And it’s cheaper. The GI-275 should have stayed square, and been the best of both worlds.
buy only cheapen less than 1000 $ need cost only. because come out of factory this panel cost 200-300$ only. dealers scammed lot and lie have expensive. big scam have if cost more than less 1000$
G5 is old technology.
I went with the GI-275. Hopefully going with the new technology will be a plus.
