I was showing 3-4amps in cruise, and it turned out the EIS was programmed incorrectly. If I recall they have to program the shunt information into the EIS and the Ovation didn’t fit the standard Garmin settings. I happened to put a clamp-on ammeter on my battery cable to check something unrelated. The clamp-on was reading double the EIS. Quick setting change in the GI-275 and it was reading properly. It usually settles down to 1amp in cruise now.

Just bought the 2.5 gallon bottles from Boeing. Less than $18/gallon, but you have to get an account with them and had to pick it up at the local warehouse. The shipping can be expensive.

AirSync says it can do that. I looked into it, but never did sign up. About 1AMU of equipment and $500/year, but it does claim to automatically send the data to Savvy among other products. https://www.air-sync.com/airsync-bridge-kit/

I grin every time too. An amazing machine! Sent from my iPhone using Tapatalk

Looking for help identifying the washer on our gascolator. Airight 51250. It’s not detailed in the Ovation IPC, and lasar could not find it either. I know they have the gasket kit, but the washer isn’t called out in that. My IA would like to replace as a it’s a little worse for wear (wallowed out hole and dinged up), it’s a pretty thin washer. It is located between the nut that holds the gascolator on. I can’t seem to locate a contact for Airight either.

Took mine to @jetdriven Some pictures below. Bottom of spinner was flush with cowl. After, the top of the spinner was flush with the cowl. Told to go fly it and check again. It’s been perfectly centered for the last 2 years. I think he checked engine mount stacking and torqued. Not sure if the mounts were incorrectly stacked or not. But it should be centered, the spinner/cowl gap is very small.

The CMM specifies the minimum power and load requirements based on your Ah rating. What I used may not work for everyone. Most dc power supplies that I found were 30v. For a 28v battery, Concorde says the conditioning charge could go as high as 34v. So I found this 50v power supply. Load tester is 500v 15A and met what I needed but may not work well for 12v batteries with higher Ah ratings. They have a 150v 40A version too.

Exactly. The CMM defines what the load needs to be and for how many minutes. 51 min (85%) is a good cap check. In our case with a 13.6Ah battery, we applied a 13.6A load until the battery reaches the rated end point voltage (20v for the RG24-15). If your dc load can’t do tenths, you can follow the guidance in Concorde Tech Bulletin 13. It gives time adjustments (49 minutes = 85%) if you run the test at 14A in our example. But don’t just double the load for half the time. The documentation is very good and easy to follow. Equipment to test is not very expensive unless you want the automated testing equipment from Concorde.

Just some feedback from following the Concorde CMM procedure. Batteries both failed capacity check. 85% is the minimum and we had 66% and 3%. Conditioning charge per the CMM resulted in a 102% and 88% capacity check. Reached out to Concorde, they said no impact to battery life if the capacity check and conditioning charge are followed as defined in the CMM. Used a DC load and DC power supply from Amazon ($280). Would have gladly replaced if unairworthy, but happy to put off buying two $850 batteries.

I’m just doing this myself as well. I’m having difficulty finding RG24-15 batteries. Hoping to save one that barely failed. I am using this dc power supply: HYELEC DC Power Supply,50V 6A 150W Switching Regulated Bench Power Supply https://a.co/d/5i0d3DV Concorde Manual specifies power supply and load requirements based on battery size.

Oops. Well then I am interested in any information on these too. Just replaced the $85 halogen beacon instead of converting to the $1500 Whelen LED beacon. Those are the last 3 non-LEDs we have.

Whelen LED. Couple hundred bucks, but super bright. Hangar neighbor said he can see Nav/Strobes a few miles out on final, during the day (I don’t do much night flying). Last picture is a still pulled from video of the LED strobes. Strobes are the only light in the picture.

Not an expert, but I’m planning a trip to CSE4 Lachute. It’s listed as an AOE/CAN airport, so we are applying for Canpass private aircraft program. $40/person, good for 5 years. Opens more airports for entry, and from what I understand if an officer is not present at your designated ETA, you’re free to leave. CYHU looks like it’s an AOE/15 which I believe means you can arrive with up to 15 passengers. CYUL is AOE, but I don’t think you have to go there even if you aren’t a Canpass member. Canpass just opens up the AOE/CAN airports. I’ve also always found the Canpass folks to be more than helpful at answering questions. 1-888-CANPASS https://www.universalweather.com/blog/what-you-need-to-know-about-canpass-for-business-aviation-part-1-what-is-canpass/

Sorry to resurrect an old thread, but thought this might be the best place for this question. Ovation O2 knob assembly missing this nut. Parts manual does not list what size this is. Does anyone have any better information? The actuator does not stick out far enough for the set screw in the knob to grab on without the nut. I tried a 15/32 hex nut I had laying around just for sizing, but it was too big.

Oh, then maybe I misunderstood. I thought it was 5 years to replace qualifying servos for free via the service bulletin. Then 2 year warranty from original install or 6 months from servo replacement, whichever is greater.

We just had ours installed. Roll/Ptrim/YD all mod 1. Pitch servo is only one needing replacement. We had pitch oscillations at high speed. Cleaning/lubricating trim jackscrew appears to have fixed it. Smooth as glass now. We still have 21 months of warranty and 5 years to replace pitch servo with coverage under this SB. If we see no issues with our pitch servo, I plan to keep the old one as long as possible. Replacing now doesn’t change my warranty. If I can make it until at least the end of our 2 year new install warranty, we get a new 6 month warranty after exchange. Figure if I make it to the five year mark and swap it then, it’s like having a 5 1/2 year warranty.

Anyone have any feedback on the install process yet? We just received ours as well. There doesn’t seem to be much attached to the bulb mounting wise. Just a small black housing on the back with two wires coming out.

Second vote for Dave. Our Ovation is there for annual right now.

Must be serial number specific. I believe this AFM (3600) is for 29-0001 through 29-0199 except 0183. Mine is on for start. Looks like the AFMs for 0183 and 29-0200 and up all have the Alt Field off for start. I wonder what changed?

We just had to do this in ours, this fixed the constant callouts. I didn’t realize the gps callouts are MSL and the LiDAR callouts are AGL. So we disabled the gps callouts. Also, our avionics shop said that the wiring in the unit/pigtail is not shielded and this was causing feedback in the audio panel. The shop shortened the pigtail to reduce the amount of unshielded wire in the circuit and this helped, but did not totally eliminate the feedback. It was the data packets from the gps that were apparently causing the ticking sound in the audio panel. It’s tolerable now and only audible when the engine is not running. Even with these limitations, I would install it again. Completely worth the gear monitoring.

Does the GI275 have the ground and flight calibration option as well? It would be real nice to have the accuracy for both. I think the old panel gauges were only valid in the flight attitude, thus the wing sight gauges for partial refueling.

As far as I knew, the G500Txi only shows the hottest CHT/EGT unless you tap to cycle through them, even on the engine page. And you still can’t see all 6 values simultaneously. The G3X seems to display them all on the engine page, as seen above. I like to do the big mixture pull, then enrich and see all EGT numbers increase. JPI did display all values simultaneously, and it was what I was used to. Ultimately is was just a design choice, and only cost the price of a base GI275. Haven’t received the final product yet, so can’t comment on the Aithre CO detector. Picture is obviously a twin, from the Pilot Guide.

We are just finishing up a similar process (1998 Ovation 29-0135). Our panel looked the same as yours a few months ago. We added a mircrokit LHS (ties into GPS now), Aithre built in CO detector (provides history, not just alerting), Lemo plugs all around, headphone jack for Mountain High O2D2, CiES Fuel Senders. We also worked on defrost hoses, since it’s easily accessible. Ours looked like a molting snakeskin and the company that made them apparently doesn’t exist anymore. Yours look much better than ours did. Basically we tried to think of anything that would be easier to do or address now with the panel out. Read the manuals, there’s a lot in there. Pilot Guide, AFMS, and ICA (each has slightly different info). As I was reading, we actually came up with a few changes. One was possibly removing the rudder trim indicator and displaying it on the G500Txi, not sure about the G3X. We ended up keeping it because we wanted EIS on a GI275 (wanted to see all EGT/CHT numbers simultaneously). GI275 cannot display rudder trim indicator. There is a Garmin avionics trainer, but I think it’s just G500/G500Txi. It does have the GTN navigators though. It’s windows only, so I had to use parallels to run it. There’s also iPad apps for the GTN/G500. Not sure if there is an equivalent for the G3X. https://www8.garmin.com/support/download_details.jsp?id=12373

From Map page: Menu > Map Setup > Auto-zoom on/off (or you can set a minimum and maximum level for it to auto-zoom to).

I think you’re right about the 2° flaps. If true, and depending on who you believe, it almost killed an entire plane full of people: https://en.wikipedia.org/wiki/TWA_Flight_841_(1979)
