    Fuses, Yes, Fuses

    You asked about in-line fuse holders, but those are used only in situations where a fuse bus cannot be used. I'm partial to: https://bandc.com/product/fuse-holder-6-20-slot/ but there are many high quality fuse buses from Littlefuse and other MFGs, with varying features (included ground bus...

    Methods for connecting multiple power wires

    Not necessarily "inadequate", but certainly "sub-optimal". I don't. However, here are a number of articles regarding the use of fuses, by well-respected folks in the E-AB (and certified) world: From Jim Wolper, in "Aviation Safety" magazine...

    Methods for connecting multiple power wires

    So that's not how SSAs work. The analysis is of the whole SYSTEM. And in GA aircraft, we're generally shooting for a SYSTEM level catastrophic failure rate of less than 1 per 1M hours. So either each component of the system that has a failure rate of < 1/1M hours needs redundant backup, or the...

    Methods for connecting multiple power wires

    I'd strongly suggest that you read "The Aeroelectric Connection", by Bob Nuckolls. Also, having worked in the aerospace industry for the past 20 years, I'm intimately familiar with the "NIH" and "That's the way we've always done things here" attitudes that are prevalent. Except in very few...

    Methods for connecting multiple power wires

    The data might be a bit old, but per MIL Handbook MIL-HDBK-217F (Reliability Prediction of Electronic Equipment), the failure rate of single circuit CBs NOT used as a switch in an airborne, manned environment is approximately 2 * 10e-6, or 2 per every million hours. Fuses, on the other hand...

    Methods for connecting multiple power wires

    This is an excellent point, and is a VERY strong argument for only ever having one component for each CB/fuse, and conversely having one fuse/CB for every component (sometimes it's not possible, but that's pretty rare). And THAT's an argument for fuses, which are a lot cheaper and simpler and...

    Where is the traffic????

    Traffic shows up on the 2D map, and it will show up as an icon on the main PFD screen as well (if you have it turned on for each).

    Calibrating the Autopilot using only the HDX

    Whether you have an AP head or not, did you not install a remote "Disconnect" switch, to the servos? That's the thing that you're apparently missing. If you really don't want one for some reason, you could always install one temporarily to the servos just for the calibration (but I strongly...

    121.5 one button tuning

    One exception - per 91.215(c), if you're in uncontrolled airspace (Class G) that is not part of the airspace defined in 91.215(b), you do not need to have your transponder turned on even if you have an operable one in the plane. So depending upon where you are, you MAY be allowed to turn your...

    LNAV+V coupled approaches appear to fly lower than I expect

    I agree with everything you said. I think the OP was mostly questioning why (if it is) the Dynon AP seems to him to be doing something different than the previous TT AP. I'm not convinced that it is, but _IF_, for some reason, the TT AP kept him on or above the GS on the approach (two red, two...

    LNAV+V coupled approaches appear to fly lower than I expect

    I believe the answer is yes, as with LOC approaches, as long as you don't drop below the altitude for the next fix. This is the most interesting point to me. The 430W is what's providing the vertical guidance (showing LNAV+V) - NOT the Skyview (or TruTrak). Either AP is just following the glide...

    What's involved in adding a second Skyview?

    I'd call it the same thing that Dynon calls it - a Skyview Network Cable. It is an unpublished proprietary network protocol. Canbus is a very specific thing, and the Dynon network isn't that.

    What's involved in adding a second Skyview?

    Dynon does not use a CANBUS. Garmin does.

    Hobbs & Tach time not recording

    Crap. You're right - that's what happens when you go from memory. Thanks for the correction. Apparently he's been flying at 83% of whatever the RPM is set to for Tach. Sigh - don't get old.

    Hobbs & Tach time not recording

    It does if your cruise RPM, as set in the engine setup, is set to about 83% or the redline setting for your engine (assuming also that THAT's set up correctly). Check your user manual for "Tach Time". It's likely that there are slight differences in the standalone OP switch and the 15 psi limit...

    Airport Offset User Waypoint

    No. The user guide is pretty clear in the "User Waypoint" section that you can only create User Waypoints using Lat/Long. There are no other choices. Of course, using Google Maps, Foreflight, or some other mapping software, one can easily determine the Lat/Long of anyplace on earth for input.

    Classic Skyview Wifi-connection issue

    Maybe, maybe not, but why would you choose to inconvenience the the folks that you're asking for help, rather than take the few seconds required to make your questions and comments more legible?
