Default G3X Touch Software Update 8.81 (4/21/2021)

Hello,

We released G3X Touch Version 8.81 to the Software Download Area today. Please note from the list shown below that many system LRU's have new software. After updating the software in the PFD1 with the SD card, the display will reset, and at that time it is best to press and hold the Menu button while it starts up in Configuration mode. Go to the System Information page on the PFD1 and watch all devices completing the software update before taking the PFD1 out of configuration mode and verifying proper operation for the updated system.

There are a few frequently requested updates included in this revision, such as the transfer of fuel flow data to GTN (Xi) Navigators. Our primary mission is to increase the margin of safety for owners and operators of EAB aircraft, and we are very happy to also include a number of updates that improve system reliability and redundancy in this release. Several of these updates will be migrated to a GDU 3XX software update, which will be released shortly after this update.
  • One of the most frequently requested updates we have received is to allow fuel flow information to be sent from the G3X Touch to an adjacent GTN (Xi) Series Navigator. This G3X Touch software update will make that data transfer possible. Updated GTN (V6.71+) or GTN Xi (V20.12+) software is required for this to work. The GTN Software update can be found using the same link provided above for the G3X Touch software. Once the GTN is updated, change the ARINC input on the GTN (that is receiving data from the GAD 29) from EFIS FORMAT 2 to GDU FORMAT 2. You will then be able to select Use Sensor Data on the GTN (Xi) Fuel Planning page. No configuration change is required on the G3X Touch side. Fuel Remaining is also sent to the Navigator using this datapath.



  • Display of Rotax FADEC information in normal mode. This can be accessed from the ENG menu, by pressing the MENU button and selecting FADEC Information. Alternatively, press MENU twice, select Setup, Engine, and then FADEC to view this information.



  • Added support for a second GMC 507 Autopilot Controller. This can be especially helpful in tandem aircraft, as it will be possible to install a dedicated autopilot controller in both positions. Identification of GMC 507 #2 is accomplished by strapping pins 1 and 2 on the GMC mode controller connector.
  • GEA 24 P Lead RPM Sensing. 24.3.5.3 of the G3X Touch Installation manual, revision AN provides specific installation guidance for this type of installation. A MOD 2 GEA 24 is required to make a direct connection from the GEA 24 to a P-lead for these purposes.
  • Provide DST data on GARMIN VHF NAV output, to an SL 30 NAV/COM. To enable display of this information on the SL-30, Press SEL while in NAV mode. Turn the large knob to the DST datalist. Press ENT to enable the display of DST data.



  • Added 3rd ECS External Light Priority Mode. The new Switch OFF priority mode will cause the external lights to remain off when the corresponding switch is off, regardless of the current flash state. If the switch is on, the lights will either be on or flashing, depending on flash state.
  • Improved redundancy in communication between transponder and GDU. A transponder communicates with the G3X Touch system through a serial connection to the GSU 25. The GSU 25 typically already has a backup RS-232 datapath to the GDU in place for ADAHRS data redundancy purposes. In the event of a CAN bus failure, the transponder can now use that existing backup RS-232 datapath, providing GPS data to the GDU if the transponder is an internal GPS model, and making transponder remote control possible.
  • Further improved redundancy of transponder datapath. We now make possible an RS-232 connection from the transponder to a second GSU 25, in dual GSU 25 installations.
  • Fuel flow can now be configured in the Units menu, to display in pounds or kilograms of avgas.
  • Added miscompare monitoring option to PFD Configuration page. In a system with a single ADAHRS LRU (GSU 25/73), selecting "ADAHRS + SFD" will always perform miscompare monitoring between the standby flight display (G5) and the ADAHRS LRU. In a system with multiple ADAHRS LRUs, selecting "ADAHRS + SFD" will only perform miscompare monitoring between the G5 and GSU 25/73 when the system has been degraded to the equivalent of a single ADAHRS due to the loss of all other ADAHRS LRUs. If set to Disabled or ADAHRS Only, the G5 will not be compared with the GSU 25/73.

    If a miscompare condition is detected, a CAS message will be populated to describe the condition. A miscompare between a G5 and GSU 25 does not disengage the autopilot, but depending on the nature of the miscompare, may disarm envelope protection on one or more axes, which is also annunciated with a CAS message. This feature provides confirmation that your G5 and GSU 25, which calculate attitude differently, agree on the attitude and air data values. If they are in disagreement, we flag the condition to the pilot, and prevent ESP from providing control input based on potentially incorrect GSU 25/73 data.

This is a link to our G3X Touch Manuals page, you can find the most recent revisions of the Pilot's Guide and Installation Manual here for reference, as well as several other helpful links.

Default Justin, please clarify...

...allow fuel flow information to be sent from the G3X Touch to an adjacent GTN (Xi) Series Navigator.

Can fuel flow info be sent only to Xi navigators or to GTN750 non Xi navigators as well?

Thanks

This works for both the GTN and GTN Xi Series Navigators.

Thanks,

I have a GDL 50R providing traffic and WX to my two G3x Touch units via Bluetooth on one and hardwired to the second. Does this new release support all the WX functions via the hard wire or is it still necessary to use the BT connect for that data?

... and now that I refreshed, I see the same question above ^^^^^

Justin, because i dont see it, I’m guessing I know the answer, but any updates on when the newer FIS-B weather products will be available over RS232 versus bluetooth?

For some reason I just dont get reliable Bluetooth connections between my G3X and 45R.

Thanks

Justin - I am I correct this will not work with the GNX375? If so, any plans to expand the software revisions?

Thank you for this update and in general for your interactive approach to experimental avionics customers. Is there a document that gives a deeper description of the improvements? The one I am curious about at the moment is "Improve audio alert output" - what improvements were made?

Justin:

So, still nothing done to improve the interoperability of the GNX375 with the G3X. My IPad can still control my 375 better than either of my 2 x G3X screens. As a PFD or MFD, it is quite sad that an IPad can fully modify before or during flight you entire flight plan. The current G3X software only allow you to switch to internal GPS to make VFR changes to a flight plan. We still have no capability to create a full IFR flight plan to include SID, airways, STARS, or full procedure approaches. All of these are easily achieved with ForeFlight and and iPad. The GNX375 will send update or receive update to the IPad.

Last time we spoke, your software engineers were looking into it. This was back in Aug 2020. Any updates?

This is something we had considered looking into next. I will bring this back up with the team for discussion.

Thanks,

Good Morning,

Here is a quick update on the addition of the newer FIS-B products to the RS-232 datapath. The GTX X45(R) software required for this to work was released in March of this year. We have the required GDU updates planned to be included in the next G3X Touch software update, later this summer. The required GDL 5X software update is planned to be released later this year.

Thanks,

Justin
