    Broken line resistor

    Skyview System Installation Guide rev AT Paragraph on page 10-10 "Autopilot System Electrical Installation" in the Figure 142 schematic the resistor is shown as 5k but they mean as close as commercially available. Paragraph on page 10-13 "Disengage/CWS Button (Roll/Pitch Servos)" says "While...

    Dynon Install guide vs Wiring Diagram (for Pitot)

    IMO because Dynon dwg 103488-000 Rev G... Sheet 13 of 15... EMS WIRING #1 - FLAPS, GEAR, CARB TEMP, PITOT HEAT shows pitot heat as "existing equipment" versus a Dynon heated pitot. Seems like a waste of an Enhanced General Purpose Input. I use pin 9 for the pitot controller white wire but I'm...

    Circuit breakers

    Re my use of 5A fuses minimum to reduce part numbers. I neglected to mention I’m speaking of protection for feeders that are usually 20 awg and never smaller than 22 awg. I prefer to use 20 awg but oftentimes purchased harnesses use 20 awg. Let's look the case of a 26 awg wire in a purchased...

    Guide for creating custom sensor definitions

    Am I correct in thinking http://wiki.dynonavionics.com/ has been replaced by https://dynon.zendesk.com/ I logged in at https://dynon.zendesk.com/ and found a category "Advanced SkyView Customization Articles" where there is "Making your own custom EMS sensor definitions"

    Static port - is this installed correctly?

    Oh, maybe he’s got some tank sealant, it works long after expiration. One can mix a little and see if it sets up. His RV-6 may have the rivet for a static port which was shown in the plans. Same rivet they used to attach the rubber baffles to the aluminum baffles. Smaller diameter than what you...

    Static port - is this installed correctly?

    It’s wrong and it makes a difference. It’s creating turbulence over the static port. The video you posted is of course the correct way. It would be convenient to use RTV unless you have tank sealant available, that’s what I would do anyway, skuff the surfaces apply RTV, fixture somehow for a few...

    Dim Out failure mode? SPOF?

    Thanks Rhino, I had to remind myself that the Skyview Dim Output is open collector PWM to ground. It took some studying for me to understand how the IFD440 dimming works. https://pilotsupport.avidyne.com/kb/article/99-ifd-dimming-setup-tutorial/ Maybe the Dynon Skyview, IFD440, and GMA245...

    Installation Monkworkz Aux Alternator

    Monkworkz MZ-30L has an output called Prorortional Current that can go to a Skyview EMS General Purpose input. Skyview EMS supports only one current shunt.

    Dim Out failure mode? SPOF?

    Dim Out… I’m wondering what happens if it is used to control screen brightness and backlighting on other devices… is this an SPOF that could make everything go dark? Maybe better to think in terms of partial panel operations and independent brightness controls.

    Resistors

    What are the values of the resistors? Which items were they packaged/kitted with?

    HDX and SV-COM-T25 audio summing resistors

    Thanks Rhino, I understand what you're saying about equalization. I don't understand when you say T25 output is not variable... there's a volume knob on SV-COM-PANEL. That's OK, I decided to KISS and not use the GMA 245 failsafe alert input that shorts to com 1 audio in failsafe mode. Now I...

    HDX and SV-COM-T25 audio summing resistors

    The audio panel I am installing, GMA 245, has inputs for audio alerts and for failsafe audio alerts. The failsafe audio alert input shorts to com 1 audio when in failsafe which is power off or audio panel failure. Garmin mentions using "summing resistors" in series with the com and alert audio...

    AP disconnect / CWS buttons for pilot and copilot

    Thanks Marc, I think you are correct. When I made the schematic of post #1 I must have been thinking a button press gets communicated back to Skyview which would then affect both servos, pitch and roll... incorrect assumption on my part. Attached is a jpg of my revised schematic.

    AP disconnect / CWS buttons for pilot and copilot

    AP disconnect buttons on pilot and copilot sticks… does anyone know… does it make sense to connect one AP disconnect / CWS button to the pitch servo and another to the roll servo? Or should the two buttons be connected in parallel and to both servos? Attached is a jpg of my schematic which I’m...
