    VOR CDi with IFD540

    What is your nav source selected to on the 540? Is VLOC source green on the upper right of your 540 screen when you are attempting VOR/ILS?

    Remote magnetometer drift

    I have mounted the magnetometer in the tail before, mounting it on a small shelf that spans the tail, attached to the mid stringer each side. Folded the edges for stiffness. I think I have a photo or two somewhere. On Cessna's, I have mounted it to a rib outboard of the fuel tank. Built a...

    D100 horizon doesn’t align with wings level

    The D100 has a remote compass module (Magnetometer). The ADAHRS system is inside the screen. Roll levelling is not adjustable, and is dependant on the screen being mounted level in the aircraft. Level the aircraft, then run a small spirit level or digital protractor across the top of the...

    Ammeter Gauge

    A good start would be : 12.5v Bottom of the green 14.5v Top of the green Pick whether you want amber or red above or below, but have a look at your aircraft/alternator/voltage regulator specs

    Ammeter erroneous reading

    If your shunt looks to be still OK and connections are all tight, have a look at the fuses that come off the shunt. There should be two. I have had these become intermittent and cause what you are seeing. The fuses are cheap, just put a couple of new ones in there, and clean the fuseholders up.

    Post Install - SV-COM-PANEL - No SV Error

    Hi Dan. I had the exact same error on a customers pretty new system in a Jabiru. Was intermittent, and then hard faulted. Dynon repaired it under warranty quite quickly.

    AOA Calibration

    If you haven't done the AoA calibration procedure, then you will have no indication on the SkyView for AoA at all. After you do the calibration, then the AoA widget will appear. The calibration procedure does seem simplistic, but it works. Follow the on screen instructions exactly during the...

    Fuel Gauge misreading?

    The Vans RV is similar. Even with 70 litre tanks, the fuel sender float tops out at about 55 litres, so that's where the fuel quantity system stops seeing a change in the signal during the fuel calibration. In this case, it will read 55+ with full tanks, even though it knows the tank capacity...

    Has anyone ever added a marine or non-aviation radio to the system

    I install commercial UHF radios in aircraft very often. They are used extensively here in Australia for mustering and station work, as well as marine UHF/VHF maritime work. I use a NAT AA34-300 commercial radio interface unit (now made by Cobham) to interface the mic, audio and PTT to aircraft...

    Max and Mim autopilot airspeed

    The inflight setup screen only takes up half the screen, as opposed to when you are on the ground where it takes the whole screen. You will still see the PFD with airspeed, altitude, etc, on the left hand side of the screen, and the setup window on the right.

    KUS fuel quantity sender

    Looks like it is a standard resistance sender. Connect one of the senders leads to a good earth, the other one connect to the Dynon wire for that tank.

    RPM sensor SkyView sytem

    The certified Dynon installation uses the P-Leads at the ignition key switch, with some resistors. The sensor that screws into the magneto are usually part of a kit from JPI or Electronics International, approved under their STC's

    An update on Dynon Certified projects

    I have installed Dynon servos in where a Trutrak was fitted. The Dynon servos bolted straight into the Trutrak brackets. The Dynon and Trutrak servos look pretty much identical. Bendix-King bought Trutrak, so I would think the servo brackets from a BK Aerocruze would fit the Dynon servos.

    What's a CHT Thermocouple's Failure Mode

    First thing to go in the rubbish bin when I unpack an EMS engine kit 👌

    What's a CHT Thermocouple's Failure Mode

    Honestly, it sounds like a bad probe. If you have a bad connection, which is in essence an open circuit, the Dynon will display a red X over that probe on the screen. Easy way to fault find is to swap the wiring over between the suspect probe and the cylinder next to it, leaving the probes where...

    roll ball is half out/ D100

    Sounds like your D100 is not mounted level with the roll axis, or there is an internal problem. Simplest way to tell would be to remove the D100, and sit it flat on a floor or bench that you have determined is actually level, with a spirit level for example. Turn the unit on with the internal...
