I'm struggling to get the correct resistor value for my IO-540-D4A5. Initially I used 30K, but I got spurious prop overspeed alarms, so I wired in a trimmer potentiometer, accessible in flight. I can eliminate the spurious overspeed warnings, but now I get spurious dropouts in the rpm...

I have defined a Degree-Volts function that takes the output of my ignition controller which provides 10 mV per degree of timing advance. This function displays properly on my engine screen.  It normally reads 0 with the ignition off, 20 (degrees) with the ignition on, and varies with timing...

Do all of the SV mapping features work if I use the Jep or Pocket FMS aviation databases? My first assumption is that it would, but never assume. Thanks, Vern

Here' a method using a fusion of some borrowed ideas and the capabilities of SV. It provides immediate results without crunching a lot of data: 1) Pick an altitude and heading, stabilize speed and engage the TRK+ALT on the autopilot. 2) Note the heading of the calculated winds and turn to that...

OK, let's face it.  Charging the SV backup battery is a problem.  We have two choices: 1) Fly the aircraft for several hours (I'm over 5 hours and it's still not fully charged). 2) Put a large capacity battery charger on the aircraft battery, turn on the Master Bus and come back in up to 4...

It would be very handy to be able to display the install guide and user's guide pdf files on the SV screens. Would simplify installation and debug... and could even be used for (gasp) checklists. For the time being, they could be stored on the thumb drive, but internally would be beneficial...

I've configured the external dimmer for my SkyView. I've noticed that in a power-fail scenario (using battery power), the screen goes very dim. The root cause of this is that the external dimmer input voltage drops to zero during the power fail, and the SV senses this and goes to it's lowest...

Dynon's interpretation of Flight Time in the SkyView seems to be at odds with common usage, at least in Canada. My interpretation is: Air time commences when the aircraft leaves the supporting surface and terminates when it touches the supporting surface at the next point of landing. Flight...

I would like a faster boot up for the SkyView system. In addition, the current boot sequence where the screen goes crazy for a few minutes gives a poor impression and may give passengers concern about the system quality. How about a more professional power-on sequence?

A couple of things I've picked up which may not be documented (I'll admit to not reading everything): 1) If you hook a Garmin Aera configured as a secondary position source to the SV and use the Aera to select airports or airport frequencies, these will be received by the SV and then pushed to...

I have a microswitch that simply indicates when the flaps are deployed. I input this to the ems via a CONTACT widget. Is there any way to use a CONTACT input as a parameter for the flaps overspeed alarm or am I stuck with just using the POSITION parameter? I can kludge it by calibrating the...

Twice today, I powered up my system and the Skyview could not find the EMS. Cycling the power worked. This is the first time I've seen this. Aircraft is not yet flying. I will check out all of the connectors and d-sub pins. I did find a bad SVN cable once before (pin not fully inserted)...

I have a situation where I am overdriving type A inputs on the EMS.  In this situation (diagram A below), current is being sunk by the EMS input, causing the LED to glow faintly. Diagram B is my proposed fix, but is it also possible to just progam the input pull-up to 200K?  I'm worried about...

I've read the white paper that describes the work-around for the pitot-static testing bug. In Canada, we need to have a static system and transponder certification every two years.  This means that a certified avionics shop does the testing.  I've had this performed several times. It is...

I'm looking to install a D700 for the GIB. In addition to the SVN and power connections, are there any other required connections? For example, will the GPS info be transmitted on the SVN to the 'slave' EFIS, or do I need to hook these wires up as well? V

I'd like to confirm that streaming air data (D10A compatible) will be one of the serial port output options on the SV systems. Our V-Speed ADS (Glareshield AoA indicator) has seen a sudden surge in popularity now that pilots find AoA a "must have".  It would be nice for the SV to drive it...

Due to popular demand, much arm twisting and feelings of guilt, our remote AoA indicator is back in production. The V-Speed ADS has more than 5 years flight experience in numerous aircraft, and is supported by both Dynon and GRT Avionics. MGL is also considering support. The V-Speed ADS is a...

This is a heads up to list members on a new product we are just introducing:  a five channel SVN wiring hub. Earlier this year, we intro'd a wiring hub for managing the RS-232 and related signals from Dynon SkyView EFIS systems (called the AXIS-15A).  See the thread...

I have a Q about the user interface on the EFIS when using the Dynon Transponder. The concensus amongst my pilot comrades is that we like the Garmin interface... punch in 4 consecutive numbers (from 0 to 7). This is superior to using a knob to set a number, push a button, then repeat up to 3...

After much gnashing of teeth, I installed a tray for the SV ADAHRS in the aft baggage compartment of my HRII. Before I close the skin, I need to route the wiring for the OAT probe, which will be located underneath the HS. Since it will be impossible to route wiring when the fuselage is closed...
