GRT Avionics

I have been flying HXr with legacy dual AHRS with the magnetometer mounted in the left wing tip. This produced satisfactory performance for 275+ hours. During the last couple of flights, I have been getting heading drifts up to +/-50 degrees and gross wind dir & speed errors. Both of these condi...

Please disregard the previous post, I now have this working

... as discussed above in this thread, I have an OpenFlightSolutions FlightBox (similar to the SkyRadar Bob mentions using above) that is providing ADS-B in. The FlightBox is connected to a serial port on the HXr. The TIS and FIS portions of the data are being read and displayed just fine by the HXr...

Hi, I routinely have a discrepancy between the totalizer fuel used and the fuel used that appears in the logbook. The difference hasn't been anything greater than 0.2 gal, so really just an annoyance. Is there an explanation?

Ah, ok. Then since I have the ADS-B in wired to a serial pin, I will attempt to have HXr utilize the GPS portion of that stream through serial, as Bob is doing through his USB. Thanks, that saves me some time.

Thanks Bob. Thought I might as well plug the little bugger in and see what happens as it is just gathering dust on a shelf. Maybe it'll come in handy when my Garmin 430W goes on the blink. Nevermind that in 10+ years the 430W hasn't so much as farted even once. My ADS-B in is via FlightBox but I use...

I have a USB WAAS GPS left over from an Open Flight Solutions FlightBox device. Was wondering if a USB GPS device like this can be read by the HXr system through a USB port, and if so, any guidance for set-up. I currently keep a USB drive in one USB port for data/logbook download and a bluetooth don...

Today I flew multiple practice approaches using the HXr driven by a Garmin 430W. The flight plan and nav mode source are set to external. The system performed flawlessly during a full procedure turn. I then "EXECUTED" the approach on the HXr when established inbound. The system displayed l...

The built-in approaches on the HXr proc software and database are a separate function from the Garmin. If you are trying to fly an approach from the Garmin, do not load the approach on the HXr. You should have the HXr follow the external flight plan and use the ARM function to capture the approach ...

re #2. What does the 430 annunciate? Does it say ‘LPV’? I have seen some confusion where there is a long straight in segment from the IAF, with step-down fixes leading to the FAF. During the step down segment, the 430 will say ‘terminal’ mode, and there will be no glide slope. Just prior to the FAF...
