The Dynon OAT is a solid state thermistor, with no moving parts, whose service life will most likely match that of the aircraft. With that said, if you are concerned about removing the OAT after install, include a service loop in the harness that can be cut to facilitate easy removal and...

What Glenn said. Install using the Dynon provided connector and don't look back. Highly unlikely it will ever need to come out again.

Here is a popular example from Bob Knuckols @ Aeroelectric.com showing how to use two S700-2-10 switches. Note that there is one error in the diagram. Since the PMAGS are self-powered above 900 RPM, the ground wire for the PMAGS needs to be grounded to the engine case, not the firewall.

Yikes! That is anything but intuitive. Dual PMAGS, if you haven't already, download the PMAG schematics from https://emagair.com/ to map out how PMAGs are powered, grounded, placed into setup mode, configured for different timing curves, etc........ Lots of ways to do it and lots of ways...

Push to start is a very simple low voltage circuit that activates the starter solenoid as drawn in the diagram below which also shows an optional LED that flashes when the starter is engaged. The key switch, or alternatively toggle switches, are used to manage the state of your ignition P-leads.

Given the severity of the alerts, I would ground the plane until such time you can determine the root cause of the warnings. I.E. False positives or real? As suggested, you should export the logs and then use the free analyzer at Savvy Aviation to determine how and when EMS / ACM faults...

Download the D180 installation manual and review all steps in Appendix B: Dynon EFIS OAT Probe Installation and Usage. It offers some suggestions in the event your EFIS displays "OAT NOT FOUND"

OAT probes are often connected to a magnetometer. Do you have a magnetometer installed?

Yes, Garmin does have ADSB in/out in some of their transponders. However, this feature comes at a considerable cost. $$$ Depending on your design / architecture / cost requirements, the "all in one box" product may not always be the best solution.

The RV-8 is one of the few aircraft that can take advantage of the Dynon Fast Track mounting system. There is plenty of non-obstructed space between the rear of the SV-HDX screen and the front baggage bulkhead. That is not true for other RV models. I used two Fastrack trays to mount two back...

Smaller and lighter than previous model. Other than footprint, my impression is that there is nothing new from the perspective of functionality and operations. You still need to purchase the SV-ADSB-472 Dual Band ADS-B Traffic and Weather Receiver. Am I missing anything?

Not sure but the MAP key is already programmed to do this. Press the MAP key for 2-seconds and the airport diagram will be displayed

I use to have a small LED on the panel that would illuminate when my boost pump was on. It was on the periphery of my vision and was frequently ignored. When I upgraded my system to Skyview HDX I created a digital indicator and placed it directly beside my RPM gauge. Now it’s always in my...

Hi Knut, I have an O360 with a carburetor air temperature sensor. During startup and taxi the Carb Temperature will always read much higher than the OAT. I.E. OAT 27°C, Carb 50°C. Once I start my takeoff roll the Carb Temp will rapidly decline. Carb Temp = OAT around 100 KTS IAS. Best...

My situation: Dual HDX / ACM. Transponder hung after update. What I found is that just rebooting (1, 2, 5 reset) the HDX screens didn't fix the problem. What did fix the problem was shutting off the battery master switch and insuring all systems were powered down before turning on the...

Were the headset jacks removed? Do you have shoulder and fiber washers installed on the headset jacks?

What are you seeing for amperage when this occurs? Check all your cables. Make sure they are well seated. Pins 1 & 2 on your EMS harness is where voltage is measured. Pin 1 is typically your main bus voltage, pin 2 would be for a custom point. Measure the voltage coming into pin 1. If...

Need more specifics. I would start by downloading the EMS data log. You can then review the Excel file for correlations and anomalies. You can also upload it to Savvy Aviation to graph and analyze various sensor readings. You mentioned that the problem just started showing up. Depending on...

Could be a bad probe, a bad connection or a problem in the EMS. Check the spade connection crimps. If still reading incorrectly, swap the spade connectors from #1 EGT with #3 EGT. If #1 is reading incorrectly then it’s a bad probe. If #3 is reading incorrectly then the problem is either in...
