GRT Avionics

I have EarthX batteries for both my main and backup batteries. Both offer a fault indicator signal (which can also be connected to a simple bulb). I would like to use Analog Inputs for these fault indicators, preferably for warnings titled 'Main Battery Fault' and 'Backup Battery Fault' that would b...

I am installing an ATEX 345 406 ELT. Mine can receive Aviation format GPS at 9600 Baud Rate with the RS-232 connection. (NMEA at 4800 Baud Rate can be configured before purchase). I connected it to the Horizon, but I currently have a TruTrak AutoPilot, so am using the the Autopilot (Aviation) 'role'...

Support got back to me and said that the Hourmeter is the mechanism that builds Tach time. Therefore, if there is a desire to not count time at idle, etc., then setting the Time-RPM setting is the way to do this. This sounds like a reasonable approach to me. I'm thinking 1200RPM at the moment, but h...

Since purchasing my RV-7A with an EIS-4000, the tach time aggeregation has been virtually the same as Hobbs time. That is, tach time always matches Hobbs time. RPM displays consistently and correctly. My understanding is that tach time should be a function of RPM. The Hourmeter seems to run above a ...

As with my other post about the Internal IFR, I'm asking for experience with the touchscreen option on the 10.1. A good discussion in the HXr on where the touchscreen is good and where buttons and knobs are better. (No arguments there.) In that thread, Jeff noted that there is no manual or demo for ...

Thanks Bob!
I agree, it is a shame.

I'm trying to decide which options to get on the Horizon 10.1 and have an IFR GPS NAvigator (GNZ 375). As a result, I don't see a good reason to get the internal IFR option. Perhaps as a backup...? Interested in different viewpoints. Currently have a 2 HX EFIS installation, but one EFIS is becoming ...
