I had a problem a ew months ago with high Oil Temps, that turned out to be due to accumulated sludge in the oil cooler. Once I sent the oil cooler out to be pressure flushed and cleaned, the problem went away. In the process of discussing this with many folks on this forum and the COBA forum, it...

I had ATC report to me inflight today that they were not receiving my Mode C (altitude data). Intermittently, they also reported they were not seeing any other transponder information. My transponder is a Dynon SV-XPNDR-261 Transponder which includes ADS-B out, and after I landed I went to...

In the installation document, EMS 220 chapter, (on page 7-73), you recommend that a carburetor temperature sensor be connected to pin 23. However, if someone wishes to install two capacitance type fuel level sensors, the document specifies, ( on page 7-61), that only pins 8, 22, 23 or 31)...

Since the last version update, (it was 16.2.4), When I go to the add fuel menu, the current quantity always reads as 0.0, no matter how much fuel is indicated on the fuel remaining widget.

I already have a landing gear warning light system in my Long EZ, containing a microswitch on the nosegear, an airspeed switch and a microswitch on the throttle. It is set up so that the light comes on when airspeed is below 80KIAS, throttle is below 50%, and the nose gear is not fully extended...

I am trying to add a second voltage widget to my HDX screen, to monitor the voltage output of my alternator, using pin 2 (yellow wire), on the EMS-220 DB-37. I hooked up the yellow wire from the EMS-220 DB-37 wire harness (pin 2), to the point where I wanted to monitor the voltage, (alternator...

Tried to load the latest update file this morning (SkyView_16_0_8_US_Package_HDX1100_Dec02.duc , from 2 Dec), and it failed. It ran for about 4-5 minutes, (re booted once that I saw), and got to the point where it was cleaning databases, then screen went dark then light Grey but nothing else...

I have Skyview HDX with EMS-220 computer. Recently I had errratic voltage indications on my HDX. The voltage would intermittently jump up from it's normal 14.4-14.5 volts reading to 14.9-15.2, with associated audible "high voltage" warnings. At first this was intermittent. The high voltage...

Can the D3 display GPS position? Dies the synthetic vision display only show terrain height, or dies it also show other geographical features? If it has terrain data, and GPS lat/long, ... ?

What are the requirements to get the glide slope indicator to appear for an ILS approach? I have HDX with Skyview v16.0.4, and VAL Nav2000, and tried one yesterday, and I definitely captured the Localizer, but the GS bar never appeared. Do you have to be within upper and lower limits of the...

I have a VAL NAV 2000 wired into my HDX display. When I cross over the outer and/or inner markers, should I be getting some indication on my display? Or do I need to install an additional light on the Panel hooked up to an output ssignal from the NAV2K or tHe HDX?

I ma experiencing pitch oscillations, i.e., the Altitude hold is not stable, Altitude oscillates up and down around the target altitude with magnitude of between 30 feet to 180 feet, with a period of about 35-45 seconds. In the Inflight Tuning process guide, the only thing I can find that seems...

Could the HDX system be modified so that ADS-B/TIS traffic, (and maybe weather as well), be displayed on top of approach plate and SIDs, just like on the main Map display? The system already shows moving own aircraft icon on the plate, so it can't be a major code redesign to do this. Currently...

I loaded the HDX data file from 15 JuLY, which was supposed to contain updated version of these files, but they have expired. Wassup?

Is there any way to calibrate the oil temperature sensor to make sure it is sending the right signal to the EMS? Also, I have been told that single wire oil temperature sensors (that use the engine crankcase as pathway to ground) are frequently unreliable due to ground loops and that two-wire...

I have been trying to reach Dynon support all day (at 425 402-0433) and the phone service at that number seems to be disconnected or out of service, or something... Has anyone else seen this?

I am suddenly getting this message intermittently. When it happens, and I run the Network configuration Detect function, it fails to find the AP-Panel. But if i shut down and restart the HDX, it finds it okay. I have checked that the connections are tight, and the pinouts on the network wires...

Should I use the same pinouts for the Garmin GPS175 db25 connector as are specified for the Garmin 430/530 in the SV-ARINC-429 Installation section of the Skyview Installation guide (Figure 156 on pg 12-6 through 12-8) ? (ignoring the VOR/ILS stuff)

Am I correct that a small amount of play in the connection between Pitch Servo pushrod and the pushrod it attaches to (between the Stick and the Elevator BellCrank) cause the Autopilot to oscillate up and down around the target altitude in Altitude Hold ?

Anyone have any experience with adding Screen protectors to the HDX screen? I am looking at product from Photodon... Dynon SkyView HDX 1100 10-inch Panel Display Screen Protector (photodon.com) Does it negatively impact touch functionality or anti-glare visibility or clarity at all?
