Garmin GI 275, ADI, HSI, EIS review

[@savagecub]

Outstanding ! Your avionics bill now exceeds the entire value of the aircraft !

[@breddi1]

Many of us spend as much on the panel as we do on the acquisition of the plane…. I’m in that club. That being said I’m in full agreement that to do that in a Cessna 150 is kind of nuts… unless it’s intended to be an IFR trainer. I can’t imagine anyone would really consider a 150 for a legit IFR traveling aircraft.

[@AvgDude]

My C150L is currently in the shop being transformed into a TAA. The Trio Pro Pilot digital autopilot just got its STC for 150s. I already have an IFD440 GPS, ADS-B In/Out, Mode C transponder, a JPI EDM 900 primary engine monitor, and SL40 COM2. I’m swapping out my two G5s with a Garmin G3X 470 7” portrait PFD which will make my 150 a true technically advanced aircraft. I have my Instrument rating and have flown the plane several times in real IMC. The new autopilot will allow for coupled RNAV approaches to 500 ft AGL. It doesn’t do coupled ILS though. I think the autopilot will do wonders for alleviating fatigue on long flights, although the plane will still be slow. But I fly the plane for personal travel; so I’m in no rush.

[@orlinlewis622]

Best video I've seen so far on the GI 275's. Thanks...

[@amy7211]

Thanks for this video. I’m getting two GI 275’s installed in my B36TC and I’ve been searching all over for someone to show me how the knob and touch screen work together. You covered it for me. Now I’ll be more prepared to fly my baby home from the avionics shop next week. Thank you!

[@mattolmstead6150]

How are you liking them?

[@amy7211]

@@mattolmstead6150 They’re awesome! I love that they keep the retro look of the panel. They have beautiful screens and are very easy to learn to use. I also love that they replaced my autopilot annunciator panel as the annunciators are right on the AI. We lost about 40 lbs by removing our faulty vacuum system. The database downloads via WiFi from the 275 and Garmin pilot are very easy to do. One thing I didn’t realize is that you cant receive traffic targets on them with a portable ADS-B in device. You have to have compatible equipment for that feature. But that’s what the iPad does for us. I also recommend getting the Garmin USB port along with it for major uploads or software troubleshooting.

[@emmonspatzer8113]

Excellent video. I am in the process of putting 275 AI and HSI units in my Turbo Arrow which has has the GTN750 since they first came out. I have pages of notes from watching your video that I will use for my post-install testing and training to assure comfort before getting in the soup. Love that you reviewed the interactions between the units so clearly.

[@stephen4029]

Thank you so much for this video. I’ve just had the 3 old standby instruments in my 2006 G1000 Cessna 182 replaced with the GI 275 standby ADI. Some of the things that weren’t intuitive for me have been cleared up in this wonderful video you have produced. Great job.

[@sphiliben]

Thanks for the shoutout. We appreciate the unseen product placement.

[@MagicBiscuitShow]

Sweet panel. Kewl Beans. 90% of my training (back in the day) was in the 150s ... the rest of my time was sprinkled among the Cherokee 140, 160, the Arrow, the Archer, the Warrior, the 172 and a 1947 V Bonanza. Also, got my multi in a decrepit Piper Apache. Cheers, Chuck (NE Florida) : +)

[@DreadnautVS]

12:39 "Twice the value of the aircraft" - That's exactly what I was thinking when I was watching this review. I'm not knocking it, do what makes ya happy! Wish I could afford that setup! Neat to see the 6 pack replaced with 2 Gi-275's though, it really cleans that panel up.

[@sethhoran7409]

Great video! I have been looking for something concise that describes the functionality of the 275's while I wait for mine to be installed. This fits the bill beautifully!

[@flymoyer3802]

That is a nice panel. Thanks for the great review. The GI 275 is just too expensive for me.

[@MediosCorporativos]

How much is the price on the GI 275?

[@keithradford4683]

Thanks for explaining the 275 options. I’m looking to upgrade my 172 and now thinking on the lines of two G5’s and one 275 for the fuel oil T & P’s.. I think they are perhaps a touch small for a primary instrument for those of us with older eyes!!

[@sparkie951]

Nice Video... One thing I noticed, you referenced the ADSB IN in the fact of not seeing any traffic, so you were good.... That is a False assumption... You can only see A/C with ADSB-Out and not all a/c are equipped with ADSB out... you only need it in Class C Airspace and above! Very nice video...

[@LeeRoyJenkz]

Wow that is the cleanest glass cockpit I have seen. Absolutely love it.

[@RMAG]

Love the name. At least I have chicken..

[@pilotgirl5953]

Very Informative! Love your comment about avionics costing more than your aircraft, I was wondering that just a few seconds prior to you mentioning it!

[@hunterofaspids5254]

Just ordered the 275 EIS for my 182. Thank you for your video, it’s very well done. Can you tell me how much weight your aircraft lost with all that old equipment taken away?

[@Devyn6Seven]

Really informative as I'm comparing these with the G5s. Thank you for being so thorough!

[@muhammadsteinberg]

I'm in the process of trying to upgrade my panel. Not trying to be noisy but can you give me an approximate figure of the install cost? You have given me an excellent idea for my panel upgrade. Hilarious when you said this is probably stupid and then went on to do it...Been there done that myself 🤫. Very informative equipment vid for me. Thanks! Btw...150/152 best trainers ever made imo.

[@Meowairn]

Cessna 150’s are valued today. More so than the past. Ppl are finally realizing their value. They are great simple very capable birds.

[@AB-jm3iu]

Great video, nice setup would of loved if you did an IAP for landing, wonder what was the down time when the upgrade was done?

[@factoryracecar]

I just updated the software on my GI275. Now it should be able to display the wind information. How do I go about it? I did have OAT probe installed of course.

[@savagecub]

I need a remote box that will give the GI275 its information. I don’t have the panel space for the typical Garmin navigators. Any ideas ?

[@dnk2566]

Well, I think the panel looks great and if you like it then it doesn't matter how much is put into the aircraft. Having said that, would you care to share the cost of such a project, hardware needed plus typical installation. Additionally it looks like the only autopilot a cessna 150/152 can have is an STEC-50. Woiuld the STEC-50 integrate with the GI 275's? What a great way to get hundreds of hours of actual IFR practice and real world in before moving into something more complex, etc.

[@clout13r]

I am getting 3 gi 275 in my 150. just for the 3 gi275 installed is going to be around 35000$ canadian. In a couple years ill add a gps, and ADS-B. that will probably be another 20 000... paid 35 000 for the plane, there is really no end to the amount of money one can spend on their plane.

[@cehupper]

Exactly what I needed! Thank you!

[@GeorgiaNFA]

What was cost of the installation of the 275 suite? Minus the GPS. I understand they run about 2k each.

[@RMAG]

The GI 275's are significantly more expensive than 2K. They start at $3,995 MSRP and installation varies depending on if they are being integrated with autopilots and what is being removed from the aircraft etc., but its several thousand dollars of labor.

[@theflightpractitioner7288]

Very helpful information - thanks for uploading.

[@andrewraymond6455]

Would you be willing to go to share a picture of your panel? I’m going to be redoing my C150M/150 here in the near future and really like the 3 GI275s

[@120archer]

We’re you able to increase your useful load with this setup? If so , how much ?

[@Cherfield-D-Blessedman]

Thanks for sharing your video. Just asking how much is the total budget to upgrade the instruments panel for Cessna 172 IFR? Please.

[@blister6884]

At 18.5 mins in you said everything that needs to be said about these! Great quality, great features, but.......!

[@karga2tilki]

awesome! suppose a C150 marketprice is maximum about 50k€ fo a good one. What is the price of the new instruments incl. Installation cost?

[@ivannova8504]

I like the panel however, you should've left some analog indicators. (Redundancy).

[@RMAG]

Yeah cause old analog gauges are so reliable for that false sense of security. There is built in redundancy with battery backups and reversionary mode between the GI 275’s. No need for the steam…

[@johncarr123]

Do you enable the built in Conext 510 functionality in the 275? Add a iPad mount with a ipad min to display EIS on the iPad using garmin pilot

[@meteorac]

Thank you for the informative presentation. Very professional. I will certainly consider this for the upgrade i plan for my 79 Bonanza. Question: Does the HSI have a built in compass or does it need an external one. I have only DG right now. Thankk you

[@RMAG]

There is a remote magnetometer called a GMU 11 that you need to provide magnetic heading. Usually installed inside a wing.

[@thunderingbuzzard]

Curious why not a G3X + optional EIS module ($12,800 total + install cost) and backup G5 ($2300 + install cost) instead of 275 Attitude ($4000 + install), 275 HSI ($4300 + install) and EIS ($4600 + install)? There is only $2200 difference for the raw hardware (not including installation) between them, but the G3X can do it all on a larger screen. Was the install cost for a G3X prohibitive? Or maybe the G3X wouldn't fit on the panel. I'm genuinely curious. Loved the video. Great setup!

[@RMAG]

G3X would not fit. We were originally going to do two G5’s but when the GI275’s came out we liked them a lot better. The EIS was an afterthought...

[@gliderfs621]

G3X would fit between the yokes, and i think there’s different sizes.

[@MediosCorporativos]

Do you have the G3X installed in your airplane, and where can I get it at that price?

[@delan-6]

What kind of avionics do you have on your plane?

[@cvlenjnir]

I am about to add 2 gi275s to my plane. I’m curious if you miss the other steam gauges. I’m trying to decide if it would be useful to keep the airspeed, altimeter, and maybe an extra cdi. Would you be good in imc with your setup? I would appreciate your thoughts.

[@madelinescafe8573]

Very helpful...thanks for the video

[@davidkagey6091]

[@georgecrothall9411]

I know this is an old video for you, you mentioned a fuel sending unit I had not heard of and didn’t quite catch the name of. Could you tell me the name of those? I would love to have better in tank sensors in mine.

[@RMAG]

[@organphil]

Thank you for this very useful video.

[@clout13r]

How much weight do you save compared to the old panel?

[@in2flying]

Great video. Question How much extra does the 930 engine monitor give you that the little 275 doesnt? Are you cramming too much engine info into that little of a circle I guess is my question, Thanks!

[@RMAG]

A JPI 930 gives you a much larger screen with all the info at once. To try to cram all that into a standard round gauge would be too much. So the most important stuff is put in the main page and supporting/secondary stuff on other pages. It works.

[@planelander]

Never thought id hear a 152 having ahars aligning lol 😂

[@dennisdunaway5956]

First I liked your Video, I am a little confused, you said that 2 275's can take the place of a six-pack. From Garmin's Webinar on the 275 it is Primary for the Airspeed, Attitude Indicator, Altimeter, and Turn Coordinator, I don't see where it is primary for the VSI. Just wondering your thoughts on the VSI removal.

[@swish6143]

Dennis Dunaway I think it is the small box beside altitude that shows VS.

[@daviddoherty1856]

I recently got a quote for 2 275s and they indicated that would allow them to remove the vacuum ai and dg. Are you sure you can eliminate the remainder of the 6 pack?

[@RMAG]

As long as you have both GI-275’s With ADAHRS and Batteries and reversionary switch. Your installer should know this if they read the STC.

[@PilotDaveAviation]

Wow that looks amazing !!!

[@BFETile]

What was complete install cost for this? Thanks

[@kmartin3104]

My gi-275 has temp probe installed but for some reason not showing OAT that i can see or Standard rate turn bank angle markers either, wonder where the problem is?

[@RMAG]

It’s either the probe is not connected properly or it’s a software config issue. Have your Garmin dealer/installer fix it.

[@kmartin3104]

@@RMAG yeah i called them about it. thanks

[@joseleonardomoreno8957]

How much would it cost me to put a similar package on mine ?

[@Cess08van]

Thanks for sharing. Really nice!

[@tsuranix]

Can you comment on the regs for this install? I wanted to get rid of all my analog gauges and replace w/ G5s and GI 275, however, we ran into an interpretation where the ASI and Altimeter could not be replaced solely with these units.

[@RMAG]

This interpretation is correct for a G5. The installation of the G5 requires the retention of the mechanical airspeed indicator, altimeter, and vertical speed indicator. • For installations in aircraft approved for IFR operations: • If the G5 is installed as the primary attitude indicator, the existing rate of turn indicator must be retained. • If the G5 is installed as the rate of turn indicator, the existing primary attitude indicator must be retained. • For installations in aircraft approved for VFR-only operations; • The G5 can be installed as the attitude indicator and rate of turn indicator without retention of either the existing attitude indicator or rate of turn indicator. The GI-275 does not have these limitations if you use two ADAHRS with battery backup versions. Have your installer read page 1-31 of the GI 275 install manual

[@tsuranix]

@@RMAG Thanks! I'll read more on the 275's. Any idea why this is ? Do the 275's meet a different reliability standard that the FAA has?

[@RMAG]

@@tsuranix G5’s were experimental units that were adapted to and became approved for certified aircraft. GI-275’s were designed from the beginning for certified aircraft and is newer technology.

[@chriss5549]

Did this installation add useful load, or was there no weight reduction with the modern avionics? Thanks for all of the info!

[@RMAG]

There was no weight reduction on this specific install.

[@xpjet9696]

@@RMAG Just bought a 150 and may do similar panel. How is it that there is no weight savings after removing all of the old gauges and instruments? That's part of the reason I want to do the upgrade. Thanks for the detailed video!

[@RMAG]

@@xpjet9696 it’s the GTN 750 with the remote transponder and audio panel and we added the sensors for the EIS, added a second NAV/COMM. so we added stuff that was not there before.

[@in2flying]

I know this doesn't apply to the trainer your in but the concern i have on the 275 vs the G5 is the back battery. Thoughts?

[@RMAG]

What’s the concern? The G5 has a longer battery time than the GI 275. But if your running on battery that means you’ve had a complete electrical failure. Normally if you are having a complete electrical failure you lost an alternator, you turn off non-essential, equipment, declare an emergency, and land. If your main battery gets so low that your avionics completely turn off and you’re running on the GI 275 battery you still have an hour or so to get to the ground. If this all happened in IMC and you stayed flying long enough to drain your main battery, and drain your GI 275 battery, you severely mismanaged the emergency.

Very informative, however seems very much Overkill. I would have just dropped the 275s where the ATT, DG, and CDI were. Moved the old CDI to where the audio panel was and only prob did a new Garmin audio panel with gtn650. I also wonder if you could have fit the dual USB port where the vacuum gauge was for the new install? To each there own and I'm glad you like it

[@RMAG]

It is overkill. But it was fun to do. We would be happy to do your panel just the way you would like.

What do you use for a clock to be IFR compliant?

The clock is a mid continent www.truebluepowerusa.com/products/aviation/usb-charging-ports/md93/

[@brentfitzgerald755]

I’m not familiar with all the features of a Garmin 750, but if it has a clock feature, which I’m sure it does, then that will suffice for meeting the IFR clock requirement. Not to say the Mid Continent clock isn’t worth installing, though... www.faa.gov/about/office_org/headquarters_offices/agc/practice_areas/regulations/Interpretations/data/interps/2016/Nkugba%20-%20%282016%29%20Legal%20Interpretation.pdf

[@HoundDogMech]

I want to see what you do when your Solid and yo loose an alternator with your GLASS. My very first for real IFR flight after just getting My Instrument ticket I had to go Needle Ball and Airspeed for real when Making a turn in the clouds and the Vacuum Horizon takes a Crap. No Problem I was most proficient in Needled, Ball, & AirSpeed as I had just taken my Instrument Checkride. How Proficient are you at flying/Navigating with 2 half size steam gages in the lower part of the panel when all electric power is lost. It happens in older planes that have upgraded Glass Panels installed with that increased electrical draw on a 50 year old system.

[@RMAG]

If you lose an alternator you get a low voltage warning. You cycle the alternator, if it does not come back you immediately declare an emergency, fly to VFR conditions if practicable, or shoot an approach to the closest airport. If your alternator fails, you still have your primary battery, if that gets too low these instruments all have their own backup batteries that will give you an hour to get on the ground. Fortunately with these electric gauges you can’t have a vacuum horizon take a crap as the vacuum system is eliminated. No idea about half size steam gauges, we don’t have any. We have all new wiring, new battery, alternator, etc, no 50 year old electric system.

[@stevekiss6277]

Ugh Why do I feel Garmin is going in the wrong direction with the newest products... I have flown behind a lot of Garmin in the last 15 years... currently GTN, 396, 33X, GDL, Etc..... the 275 EIS appears nearly unreadable... add to that that EGTs are configured on the second screen and I just shake my head. Minimalist is great.. but from a human factor perspective, not having the peripheral vision to something as costly (and deadly) as EGT just stinks. Garmin developers need to fly more old aluminum and less carbon. And they need to do it in moderate turbulence. I want to get rid of my vac pump but the cost (in all senses of the word) is not overcome with this product. The EI and JPI products are more relevant to the average pilot. I an dumb it down... on a steep climb on a hot day in heavy weather and lots of radio work I glance at my EGT to keep me safe. If I need to scroll to the second screen, process the number coming at me... it simply won't happen with the regularity needed to prevent cooking a cylinder. Oh and in the bumps as an aging pilot... the letters are just tooooo small.

[@RMAG]

It has the max CHT on the main EIS page which is what you want to watch for temp. EGT is mostly used for leaning. This is no different than the G500 TXi. Shows max CHT for temp monitoring and you can access further engine data one button away.
