    AUDIO OUTPUT FAIL

    All, During my last few flights with a dual screen HDX system, I’ve noticed that the audio output from the Dynon is slightly garbled. Has anyone else run into this? I’m not getting any error message and the problem is likely a loose connection somewhere, but thought I’d pose the question...

    Autopilot and coupled LPV approach

    This issue still isn’t resolved. Once I intercept the glideslope/vertical guidance, the aircraft starts pitch bucking. I’m not sure what to make of it.

    Pitch Bucking during VNAV Approach

    I have a Glasair Super II with an HDX, AP panel and auto-trim. My aircraft has a Ray Allen servo controlling a movable tab on the elevator for trim. In general, the AP works great, but I often notice that when I go from fast to slow or slow to fast requiring the Dynon to re-trim the aircraft...

    SV-AP-TrimAmp yeah or nay?

    Question: I already have the AP Panel with Auto-Trim enabled in an HDX system. Can someone tell me the additional features I would have if I install a TrimAmp unit in my system?

    TrimAmp installation issue (or possible failed TrimAmp)

    My Glasair has a larger linear actuator trim motor, so I decided it necessary to install a TrimAmp device. During my avionics upgrade a few months back to all HDX equipment, the TrimAmp wasn’t available, so I had to improvise with a TCW Technologies unit in the meantime. I’ve finally got round...

    Audio cable from Dynon to audio panel

    But here’s another problem, and really my final, known problem with my installation. With the engine not running, If I turn EVERYTHING off. except for the two HDX screens and the intercom, I hear a faint clicking noise and a faint buzzing noise. If I turn the HDX screens off, the noise goes...

    Audio cable from Dynon to audio panel

    UPDATE: So, ultimately this matter was resolved. I’ve been flying my plane for years with the SL30 and never had any significant issue with squelch break. I took the radio to an avionics shop about an hours drive away. He connected it to his bench equipment and within minutes determined that...

    Skyview not talking back to SL30

    Found it.

    Skyview not talking back to SL30

    For what It’s worth, I initially had my TX and RX for the SL30 swapped when I first powered it up. It resulted in a message across the screen that said Com Failure. I don’t think that’s your problem. I still think that there is a sub-menu in the SV that allows you to choose what selections...

    HDX showing bearing to VOR, but no HSI displayed

    Ok guys, I have to fall on my own sword on this one. I had the SL30 wired properly and I knew that the head type had to be set to “None”. Unfortunately, I had selected “None” in the Nav CDI info menu, NOT the main setup menu of the SL30 that is accessed by powering it up while depressing the...

    Skyview not talking back to SL30

    If that’s a SV Touch, you might be able to just touch the (CRS) indicator on the screen and it will change the knob function to (CRS). Worth a try.

    Skyview not talking back to SL30

    Can you not push one of the multi-function knobs on the SV, select (CRS) to then have control of the OBS? If the multi-function knob doesn’t offer the (CRS) selection, it seems like I recall reading that you can select (somewhere in a menu) which options are available when you push the...

    HDX showing bearing to VOR, but no HSI displayed

    Thanks Cwerner. I’ll review the settings in my SL30. I hope that’s the fix!!

    Autopilot and coupled LPV approach

    Thanks Don. I have trim speed currently set to 100% below 135 kts. I plan to increase trim motor pulse rate to see if that helps the issue.

    HDX showing bearing to VOR, but no HSI displayed

    Yes, the CDI doesn’t appear. My SL30 is not connected thru the ARIN-429. It connects direct to the two HDX screens via serial. What does the “ALLOW AUTO SWITCH” do?

    Autopilot and coupled LPV approach

    As a “work around”,, sure. I’d just prefer it to work.

    HDX showing bearing to VOR, but no HSI displayed

    Any idea what’s causing this? My HDX will show the bearing to the VOR, but doesn’t show the HSI. I hope this is operator error and somebody here can show me the way. : ). I tuned in two different VOR’s on the SL30 but no luck getting an HSI indication.

    Autopilot and coupled LPV approach

    I shot another coupled approach this afternoon, same result. Ultimately had to disengage the AP because it was bucking so much. It needed trim up, but for whatever reason, the AP wasn’t commanding the trim to actuate. After I disengaged, I actuated the trim manually to confirm that I hadn’t...

    Autopilot and coupled LPV approach

    flyindoorman, I have the same setup with the 175. Is your auto-trim continuing to work AFTER your intercept the glide slope? I flew two LPV approaches this afternoon. It trims fine until it intercepts. It stops auto-trim and ultimately has servo slip once it can’t handle the load. Odd issue.

    GPS175 Power Pins

    This should be all that you need. Also, please note that as regard the tiny little config module wiring, the yellow wire is ”Data” and the white wire is “Clock”. I had to ask Stein for this info as I could not locate it in the Garmin install manual for the GPS175. I highlighted below all of...
