GRT Avionics

We had other modules a long time ago but only the Safe-Fly now.

The Stratux and other standard receivers send some limited GPS data as part of the traffic interface. The EFIS can use this if you turn on SET MENU, Display Unit Maintenance, "Advanced ADS-B Receiver Settings", and then configure SET ...

On the 10.1, the Density Altitude is displayed above "D-Alt" in the text data fields around the middle left of the ENG/MAP page (SCREEN, ENG/MAP). It can also be configured to show in any of the top left, combo inset, or PFD/PLATE data boxes using the Box settings in SET MENU, Graphical Engine ...

In my experience this usually means the file or filesystem got corrupted, not that that the EFIS actually tried to write that. I would check the drive for errors to make sure all data blocks are marked properly (the quick check, not a full block scan). This can be done with the drive Properties on ...

Not yet. We need WiFi capability, which is on the to-do list. With WiFi software and a USB WiFi adapter we should be able to read from any receiver that has a standard WiFi ADS-B traffic/weather output that works with most apps.

The EX doesn't have a split page checklist mode and the only way to access the checklist is through the full screen map menu.

It looks like a GPS week rollover issue. There are old GPS receivers out there (or external GPS units with very old databases) that no longer know what time period they are in. GPS satellites count up to 1024 weeks, but they don't specify what period of weeks those are. The GPS has to know that. We ...

Beta updates for the 10.1, HXr, HX, and EX are now on the web site.

Fixes warnings incorrectly generated for gear locks that aren't configured.

Fixes warnings on takeoff and improves warning situation during go-arounds.

Sends gear lock inputs over the display link. After configuring inputs and ...

I found it in the ARINC 429 GAMA data. It has the ability to say LNAV, LNAV/VNAV, LP, and LPV. We'll have to figure out what we're going to show and where.

Around serial number 481. You can tell the generation by the screw patterns on the back. The 2nd generation and later has 4 more screws, with 2 screws on the back near the top, and a screw through the GRT logo in the product data plate.

If the graphics are scrolling, fuzzy, smeared, or intermittent, and the backlight is stable, then it's usually a video signal issue. The signal can get better as it warms up, or with some jostling. For 2nd generation HX and newer models we can usually fix that. We don't have a supply of parts for ...
