    Autopilot tuning: Altitude Capture Procedure.

    I am seeing unsatisfactory autopilot behavior during Altitude Capture that I cannot find in the tuning guide. In my case the aircraft overshoots and undershoots the target, getting further away from the target on each iteration. In figure 5 of the in-flight tuning guide, (page 5-4), one...

    Problem with displayed winds

    I have an HDX screen, and the calculated in-flight winds displayed onscreen are (intermittently), way off. I am often getting 40 to 50 knots crosswind displayed, when the actual winds are nowhere near that strong. What could be causing this? I have my remote magnetometer mounted under the rear...

    ADS- B Traffic on Approach plate display?

    Is there a way to get ADS-B Traffic to display on top of Approach plates? If not, would you guys consider adding this functionality as a selectable option?

    GRT Oil Temperature sensor

    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...

    SV-XPNDR-261 Mode C (ALT), and ADS-B

    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...

    Installation document EMS pin assignment reccomendations

    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)...

    Add Fuel menu

    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.

    EMS D 37 contact pins.

    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...

    Adding second voltage widget to HDX.

    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...

    HDX update 16.0.8 dtd 2 Dec 2021 failed. HDX display will not boot up any more.

    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...

    Erratic EMS voltage sensor

    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...

    Necessary Conditions to get ILS Glide Slope indicator to appear

    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...

    Localizer inner and outer markers.

    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?

    InFLight Tuning diagnostics

    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...

    ADS-B In data on approach plates?

    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...

    AVData & OBData expired?

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

    Calibrating Oil Temperature sensor

    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...

    Intermittent "SV-AP-PANEL offline" message.

    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...
