I want to know if anyone has experienced a sensor error in cold weather?? Yesterday I took my first cold weather flight since my HDX install. It was about 10 degrees F. I have the Dynon EMS as well as the Dynon MP sensor. The sensor is attached to the engine mount tube. I can presumably rule...

Do LNAV+V approach advisory altitudes only apply at the fixes? Granted the LNAV+V should really be treated as a lateral guidance only with vertical "advisory", but the AP when coupled, with VNAV, should not descend below the advisory altitudes as depicted on the approach chart (according to...

I'm curious as to why the menu item would be grayed out. I don't recall seeing this before. I get no messages while flying that the transponder or ADS-B out isn't working. I've not flown behind the panel enough (very new install) to know if I'm getting weather indications (i.e. radar shading) or...

I took the bait and subscribed to SA for geo-ref charts. I used their windows app to install the databases on my USB sticks. All green bubbles. Seems good from SA Chart app point of view. Now, am I supposed to delete the Dynon DBs on the same USB sticks so the SA's are used instead? The...

I think I found the D-Sub back shells that Dynon uses in their kits. These are the plastic clam shell type that can be used with either flat or round cables. Found on Newark.com. I was unable to cross the part numbers over to Digikey or Mouser so if anyone has anything to add towards that, I'd...

Seems that one of my ADHARS units is not taking a compass calibration. The message is: "Calibration failed: S/N 13751" I checked the network config and that SN is for the main ADHARS 200. This is installed in an RV-10 in the Dynon tray with the EFIS. @Dynon is there a remedy for this without...

Hi. I am installing the SV-EMS-220 engine monitor. I have read several posts regarding getting tach indications from a Surefly emag. All of which seem to point to needing the Surefly tach2 board installed. As luck would have it, I do indeed have the Surefly tach 2 board installed and am picking...

Anyone here ever notice that in the wiring block diagram, they show the Pitot being wired up on Pin 23, while in the installation guide, it tells us to stay away from pin 23 and suggests some other pins to use. Why the contradiction? I wired my Pitot status (white wire) up on pin 23 like the...

My RV-10 has a TruTrak firewall mounted EDM interface for the engine sensors and thermocouples. The EDM mounts to the firewall aft but has a firewall forward interface. That interface uses a standard 2-1/4 punch through with a stainless steel plate with the two DB25 pin connectors integrated...

Hello forum, I am in the throes of installing my HDX system in my flying RV-10. My 10 has the Ray Allen T3-12A Elevator Trim actuator. My question here is, do I need the Dynon Trim amp to run the elevator trim or can I forego that in this particular application? Thanks in advance, Mike
