    Dual Ships Batteries for Skyview Classic

    It will depend on which of the AEC architectures you're using. If Z-14, you can feed from both buses through diodes to the single power input to the Skyview If Z-19, you can put the Skyview on the engine battery bus and just not turn on the engine battery solenoid master switch until after the...

    Two independant Fuel Flow Senders

    Had you stated the information above in your first posting, I would probably have ignored you. But since the 250 gph sensor that I pointed you to (the FT-180) has a pressure drop of only 0.23 psi at a flow of 60 gph (50% more than you're looking for) and a pressure drop of only 0.92 psi at 120...

    Two independant Fuel Flow Senders

    Why don't you explain your fuel system setup and what you're trying to do, and maybe you'll get an answer that's more to your liking. Just saying "the holes in the senders are too small" is a meaningless (and incorrect) claim, so more information would be useful in assisting you in your quest.

    Two independant Fuel Flow Senders

    Ummm, then you're using the wrong sensor. Since the FT-90 can flow 125 gph and the FT-180 can flow 250 gph, either one will be more than adequate for your 40 gph required flow rate. Although the FT-60 can nominally flow >60 GPH, it's possible that your pump can't deal with the pressure drop that...

    Two independant Fuel Flow Senders

    I'm not sure what engine you're running, but the FT-180 is good up to 250 GPH, which I'd imagine is good enough for almost any piston engine out there and many turboprops. You don't need two senders if you're under 250 GPH. https://iflyei.com/product/ft-180-fuel-flow-transducer/ and the FT-90...

    VS 0 mode

    Is that true? Does it just essentially set VS=0, or does it set Altitude=<here>? Never played with that much...

    VS 0 mode

    Yes. If you push the "up" or "down" arrows when at some altitude to start a climb or descent, and then push the opposite to set the VS to 0, you'll get what you're asking for. I've never tried to see if it's better in turbulence - the AP certainly has some instabilities when in moderate chop...

    Fuses, Yes, Fuses

    Oh - forgot to add - there are these: https://www.common-motor.com/posi-lock-blade-fuse-holder that don't have any wire at all, so you can just stick the Tefzel wire into them. Of course, they're still plastic/rubber themselves, so you still have the flammability issue to some extent. I have...

    Fuses, Yes, Fuses

    The ones I pointed to are completely adequate for aircraft. While the admonition to use Tefzel insulated wire rather than PVC insulated wire is an excellent general recommendation (I ONLY use Tefzel wire for wiring when I have a choice and the opportunity, due to the higher temperature rating...

    Error log submission - need a working link

    Your log file is likely too large to email. Put the file in a dropbox/drive/box folder and email them a link to the file - they can download it.

    Error log submission - need a working link

    AFAIK, there is none - you submit an error report to the support email, and then email them the log. I've been asking for a bug/error reporting DTS (Defect Tracking System) that's open to customers for .... 15 years now? No dice.

    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).
