Default Garmin G3X Touch v3.50 and G3X v10.00 Software Release

We are pleased to announce new G3X Touch software v3.50 and legacy G3X software v10.00. As usual, the software can be downloaded for free from our website here. The updated software and installation manual is posted on our website. The pilot guide updates should be available for download later today or early tomorrow.

A complete list of changes will be included on our website and at the bottom of this posting.

Garmin ESP-X (Electronic Stability Protection)

We are very excited to announce this advanced new feature is now available on all G3X and G3X Touch systems using the Garmin GSA 28 'smart' autopilot servos. And, as usual, it's all part of a free software update! This technology is the first of its kind in the experimental market. You can find the press release here.



With installation of the G3X autopilot servos, you’ll obtain Garmin Electronic Stability and Protection (ESP-X) to provide assistance in maintaining the aircraft in stable flight. When you exceed user-selected pitch, roll or airspeed limitations while hand-flying the aircraft, ESP-X provides gentle nudges on the flight controls to lessen the aircraft’s pitch attitude or bank angle—and that correcting force grows stronger as those exceedances increase. In addition, you’ll see visual cues on the displays of G3X and G3X Touch indicating that ESP-X is engaged: Yellow chevrons provide visual pitch guidance, and configurable roll-limit indicators indicate where ESP-X engages to provide bank guidance.



As you take corrective action, ESP-X fades, and it turns off when you return to a normal flight envelope. Conversely, if the system activates for more than fifteen seconds—for example, if you become incapacitated—the autopilot engages with the flight director in Level Mode, bringing the aircraft to level flight until you command otherwise. While ESP-X will not recover an aircraft in all in-flight situations, the system does provide an extra safeguard.

But ESP-X goes beyond providing pitch and bank envelope protection to also offer high- and low-airspeed protection. In a high-airspeed situation, ESP-X engages the G3X autopilot servos to increase your pitch attitude, while built-in parameters further prevent the aircraft from exceeding G-limit load factors. In low airspeed situations, ESP-X engages to provide a gentle pitch-down force to reduce the likelihood of a stall—and ESP-X automatically disables when the aircraft is operating within 200 feet of the ground. In addition, pitch, roll and airspeed envelope protection parameters are all customizable, and for flight training or aerobatics, you can easily inhibit Garmin ESP-X within the automatic flight control system menu of G3X and G3X Touch, or with an optional switch in the panel.



Glide Range Ring

The G3X Touch Glide Range Ring is displayed as a cyan ring around the estimated area that can be reached by the aircraft in the best glide range configuration. The Glide Range Ring fades into view on the map as the aircraft climbs through 500 feet AGL. The range is based on the Best Glide Speed (VG) and Sink Rate (at VG) entered by the pilot. Best Glide and Sink Rate are combined with the aircraft's height (AGL), wind, and bank angle to determine the distance the aircraft can travel.



Best Airport Bearing Pointer

The G3X Touch Best Airport Bearing Pointer feature is tied to the Glide Range Ring function. The Best Airport Bearing Pointer points to the airport within the Glide Range Ring that is considered the best option for a landing based on the following criteria:
  1. User entered glide performance (Sink Rate and Best Glide Speed).
  2. Aircraft altitude and direction of flight.
  3. Airport elevation.
  4. Wind velocity.
  5. The expected flyover altitude (i.e., airports with 1000' or greater margin take precedence).
  6. Hard surface runways (i.e., paved runways take precedence over grass runways).
  7. Runway lengths.
  8. Runway alignment with the wind (if known).

In the example shown below, although Hayden Farm (00KS) and Gardner (K34) are closer to the current aircraft position, the algorithm is smart enough to know that New Century (KIXD) is within the aircraft glide range and is a better choice because it has a hard surface runway over 7000' long and it is oriented into the wind.



This same algorithm is used to provide a Best Glide Airport option on the Direct To Nearest Airports page shown below. This allows you to quickly and easily press the dedicated Direct To button on the display bezel, and navigate to the Best Airport. Or you can simply touch the waypoint on the moving map, hit the dedicated Direct To button and navigate. If you use NAV autopilot coupling with this Direct To navigation and set the autopilot to fly the best glide speed using IAS mode, you are now freed up to troubleshoot an emergency while the aircraft proceeds direct to the Best Airport while maintaining best glide speed.



The Glide Range Ring and Best Airport Bearing Pointer feature are being looked at for addition to the legacy G3X system as part of a future update.

G3X Touch v3.00 to v3.50 Change List:
  • Add estimated glide range ring to map
  • Add "Best Airport" bearing pointer option

  • Added support for miscellaneous temperature, pressure, and analog voltage measurement user-customized gauges.
  • Added forward and return flow display when calibrating differential fuel flow.
  • Improved fuel flow display with noisy signals.
  • Changed flight director GS and GP modes to allow capture from both above and below.
  • General improvements to system operation.

Since my wife is a non-pilot and does fly CC trips with me, I sometimes ask her: "So I just went unconscious for some reason, what are you gonna do besides sit there and do nothing until the plane either starts shedding parts or hits something hard?"

When I added the GMC305, I told her about the magic blue button but she always forgets the correct answer which is "Push the oddball blue button!".

With this ESP-X feature, even if she forgets to push the blue button, there is a good chance ESP-X will push it for her in the event I check out.

I am not even finished installing my panel and the upgraded software and features is more than I even imagined possible. I was flying under the hood the other day and I could feel the instructor lightly and then a bit more force correcting my bank in a descending turn. It took a second and then I realized what was going on and corrected myself.

What an exciting time we live in and the technology available to us - not just G3X equipped planes but all the newer EFIS panels.

Some may scoff at this and say if you can't recognize a stall or some other flight control problem, you shouldn't be flying. That's probably true. The problem is we believe we can handle everything. If we didn't, we wouldn't be up in the air at all.

Just like the sensor in my car that tells me when I am backing up Im about to hit something, I love the fact that correction can come if I get careless or try to make the impossible turn.

Great update! Hope you can make these part of the original G3X system soon.

Glad to hear our friends at Garmin are keen on copying features from a two-year old (albeit cancelled) Vertical Power product. Now if they could only couple the autopilot to glide to the best airport...

I've got a SkyView system in my -9, but this is one heck of a selling point for Garmin. Well done.

The ability to couple both navigation and speed controls during an emergency while proceeding direct to the best airport will surely save lives by avoiding distractions.

That comes off a bit bitter for some reason. Care to share Marc? We are here for you man....

Hello,

You probably noticed that this update also includes GDL 39/39R software version 4.40 which supports the ADS-B Compliance checking feature provided by Garmin Pilot for iOS V7.2.

You can run an ADS-B compliance check on your aircraft or any others transmitting ADS-B Out on either 978 Mhz (UAT) or 1090 Mhz (1090ES). As long as all the parameters are green, you are all set.

Here is a tip for those of you using a GTX23ES with either a GNS 4XXW/5XXW or GTN 6XX/7XX. If your SDA and SIL are both 0 (and red), and everything else is green, you have a properly setup and operating ADS-B Out+ link from the GNS/GTN to your GTX23ES, but your GPS Integrity is set to "VFR GPS" on the transponder configuration page.



For these installations, change the GPS Integrity field to "IFR GPS 1E-7" and the system will change to transmitting SDA=2 and SIL=3. This is the "all green" picture you should expect to see when everything is properly setup.



Thanks,
Steve

Will the Glide Range Ring be coming to the G3X classic screens or are you starting to bump up against memory/processor limits?

Hello Bob,

No promises, but we are going to work very hard to make this happen and get the Glide Range Ring function added to G3X.

Just to be clear to everyone reading, the G3X V10.00 update already includes ESP-X capability, but does not include the new Glide Range Ring function.

There is also a post above that perhaps suggests that you can't "couple the autopilot to fly to the best airport" with G3X Touch.

You certainly can. Just push Direct-To, activate the Best Glide Airport, and push the NAV autopilot button. Then push the IAS autopilot button and roll the airspeed reference to your Vg bug. Push the AP button to turn over flying to the autopilot if not already, or leave the autopilot off to hand fly with this flight director guidance. That's all there is to that.

----------------------
Update: On April 7, 2015, V10.10 software was released for G3X systems which includes Glide Range Ring support.

Thanks,
Steve
