Garmin G3X Touch Feature Wish List

[rjtjrt]

With Automatic Flight Timer, what parameters start and stop the Flight Time record?
Is it speed, and if so what speed, or is speed user set?

Hello John,

This is also addressed in the description of the flight log feature in the G3X Touch Pilot's Guide. If your G3X system installation includes engine monitoring, the flight timer will automatically increment whenever the engine is running. Otherwise, flight time recording is determined based on altitude gain and airspeed as described here:

G3X Touch Pilot's Guide - Appendix B (page 335, ref F)

Flight Log

With EIS items configured, recording begins when the engine hours timer or airframe total hours is running. This allows recording of time spent on ground before takeoff and after landing while the engine is running.

With no EIS items configured, recording begins when the aircraft reaches 250 feet of altitude. When the aircraft’s groundspeed drops below 30 knots, the flight entry is saved and a new entry is recorded when departing the airport. A touch-and-go or brief stop of less than 10 minutes appends to the current flight record, rather than starting a new entry.

I'm using an external navigator (GTN 750) and the G3X doesn't seem to recognize the "Destination".

BTW. This G3X system is awesome. It's even better than I expected - way better.

Update: I went flying this morning and noticed the following: As I was returning home, I went Direct to 52F, so that was my next waypoint. The G3X was showing Blanks in the ETED field. While enroute, I added an intermediate waypoint. After adding the intermediate waypoint, the ETED filled in with a valid time to destination.

Hello Rick,

Glad to hear you are enjoying your G3X Touch system. Upon investigation, it appears that the GTN does not output "time to destination waypoint" data when performing direct-to navigation. We're not sure why it does this, but we should be able to add a workaround in the next G3X software update. Much easier than changing certified software!

I like my G3X more and more as I get to know and manage its settings. This thread is helping us to realize that many of our wish list items are in fact available as you Experts tell us something we didn't know or hadn't read about in the several hundred pages of the Guide and Installation Manual.

I would like to change the color of the ground speed number. That maroon just doesn't show up like the white numbers. I wonder if others of you agree?

If the AP is flying the plane why not give the pilot another thing to cross check with the descent.

Also would be nice when I am on final at my very dark middle of nowhere field to see the boxes instead of just relying on ALT and vertical speed. We have no vasi and limited lights, if I could take advantage of the highway boxes it would be like having a vasi at the airport, don't have to have VASI to land but it is safer and better, another thing to cross check with ALT and what you see out of the aircraft.

Could also be used in an engine out situation guiding you to the airport, or a VFR pilot on top of a layer with an engine out, highway boxes could save his or her life giving vertical guidance to an airport.

I assume this feature is not included because Garmin does not want people flying a non published approach, but why take this feature away from people that could use it as a safety feature.

Hopefully I am totaly wrong here and this feature is available, and I just do not know how to use it.

Thanks,
Jason

On another thread a couple people asked a similar question, in particular why the g3x software doesn't allow for vertical navigation (vnav) were the pilot sets the descent angle (e.g. 3 degrees) as is the case on the g1000 and many other certified and non-certified efis. g3xpert wrote he would look into it, but never came back afaik. At the moment, the way vnav in the g3x works is that the pilot input a target fpm-rate and the g3x fixes the descent angle based on the speed of the plane around one minute before the top of descent, with no control and no visibility for the pilot of what this angle is. In particular there is no way that the pilot can reproduce exactly the same descent angle to a waypoint (or airport) on 2 different flights, despite setting the same fpm target on both flight (so if you have cleared terrain and obstacles on the previous flight, not sure you will clear on the second flight). The software modification would be extremely simple given the vnav function already exists.

Planning for panel upgrade.

I know the 430 flight plan and comm will drive the G3X, but Im wondering if I can select comm channel on the G3X will it change the freq on the 430. Also can a flight plan and/approach be selected on G3X and have them port to the 430?

Id like to move the 430 to the right side of the panel, which is doable if I can drive from the G3X.

Hello Paul,

Thank you for choosing a G3X Touch system for your panel upgrade.

Page 32-125 of the Rev. Z G3X Installation Manual provides a list of all the COM radios which may be touch tuned from the COM1/COM2 radio tuning areas at the top of the displays. Unfortunately, the GNS 430/430W does not support remote radio tuning.

If you have a GNS 430W and have wired the Connext serial interface shown on page 24-16, you may push a VFR flight plan over to the 430W from the GDU, but you can't load and activate approaches on the GDU, so it is just a convenience when you are flying VFR with the system.

When you are using external flight planning with the 430/430W, the flight plan, including any approach in use is automatically transferred to the GDU each time changes are made on the 430/430W

In summary, you will want to have your IFR navigator in a convenient location in the panel to support using all the features it provides.

Let us know if you have additional questions.

Thanks,
Steve

How about the ability for the G3x Touch to listen to and display Emag/Pmag serial data? I doubt I'm the first person to ask for this, but I can't find it mentioned anywhere else in the thread or on VAF.

I'd love to see that. Don't have the panel space for the stand alone unit.

Being someone that has deciphered the PMag's serial protocol (with help from EmagAir), I doubt they will ever take this on as that protocol could use some help. Much of the protocol issues have roots in the hardware/firmware design of the PMag.
