Your AHRS calibration (G5’s and/or magnetometer) might be ever-so-slightly off. As my experience shows, a pitch variance of less than half of one degree can cause this issue. My shop (which is a licensed Garmin dealer) is very much “by the book” which means a consistent, professional install...

Update: Problem solved! I flew extensively, including a long cross-country trip to Michigan and Ohio to see the eclipse and visit family, and I am overjoyed to report I experienced zero anomalies on either G5 during this period!!! Apr. 2: KPUJ-KVPC-KPUJ, 1.0 hours. Apr. 7: KPUJ-0I8, 2.3 hours...

Another video clip, albeit with a very brief view of the aircraft. The account provides additional context: “Early this morning, Ukrainian forces successfully conducted one of the deepest drone attacks of the war, striking multiple targets, including a reported Russian Shahed-136 factory...

Video clip of the civilian trainer, loaded with explosives, being used to attack a Russian facility. The aircraft was remote-operated. Aircraft type: https://en.m.wikipedia.org/wiki/Aeroprakt_A-22_Foxbat

I read on another forum that a G5 firmware update prevents the yellow heading from turning off autopilots. I don't have autopilot myself so I can't say for sure. The latest version for certified aircraft is 8.26.

2 G5s, a GNX 375, GTR 225, and a PMA450C audio panel. It felt like a big upgrade to me. Why do you think it is electromagnetic? My avionics shop hasn’t charged me for this troubleshooting. They really wanted to fix it. I lost count of how many AHRS and magnetometer recalibrations other...

It is random. I’ve tried all power settings, turns, climbs, stalls, etc. It happens when it wants to happen. See the confidence sawtoothing graph. Note the sawtoothing is algorithmic, not triggered by a certain flight condition. The G5s normally show the heading anomalies one after another, not...

There is a vibration test which runs the engine through different RPM levels. We performed it on the ground as per Garmin’s instructions and the G5’s passed.

I don’t know what to think anymore. I uploaded my data to another forum and one of the guys there put my last few flights on a graph for me. You can see the G5’s confidence level represented by the blue line. Altitude is the red line. The confidence sawtooths, starting each flight low and...

Those who think I’m “bashing” Garmin must be convinced there is nothing wrong with the Garmin G5 hardware or software (which continues to be patched with updates) or stringing us along for 6 months.

No. Although it seems to have improved, I still got the yellow heading. Here’s how my latest flight went: Segment 1 (KPUJ-KRMG-KCZL): Immediately after takeoff, I got yellow heading anomalies on the top G5 (AI) and the bottom G5 (HSI). I took a video of my takeoff...

Include a footnote with a link to this thread ;)

Not just that, my letter was primarily aimed at a preceding interpretation (the Nkugba letter) rather than a regulation. I get that people may be intimidated by lawyers but I don't think the FAA chose its words carefully when it came up with "permanent clock display" and "permanent clock...

All it took was a letter to the FAA about clocks and I somehow triggered half of POA into underwear-twisting cartwheels about the mere possibility of an unfavorable interpretation. :lol:

To all those hemming and hawing that I kicked the metaphorical hornets’ nest: If my letter prompts the FAA to tighten the rules for digital clocks, I’ll apologize to everyone in this thread. If my letter prompts the FAA to relax the rules for digital clocks, everyone who chewed me out should...

What’s the punch line? I’m trying to get clarity and I argued to relax the rules, not tighten them. The “permanent clock display” interpretation in the Nkugba letter is absurd if taken to mean (as some pilots and examiners believe) that the clock must always be displayed.

He explains that even though the Davtron doesn’t always display a clock, the page is always accessible: In the case of an installed clock such as the Davtron models, you cannot turn the clock "off." Using that definition, there are many, many devices that would qualify as IFR clocks. My GNX-375...

There are two possibilities: 1. The Office of the Chief Counsel deems the matter posed by my letter neither significant nor novel, and sends me a letter that it will decline to take up the issue. Or 2. The Office of the Chief Counsel decides to take up the issue. If so, it will probably be...

It’s my nickname people have called me since I was 9 years old, not a call sign, but thanks for whatever that was. Anyone want to talk about clocks for IFR?
