Greetings VAF!

We are very excited to share information about a new Garmin product available for purchase now, for your experimental aircraft.

Garmin has decades of experience innovating avionics and tailoring designs based on feedback from customers like you. In 1998, Garmin’s GNS 430 took the industry by storm by combining an IFR GPS and NAV/COM into one unit. At the time, this was a revolutionary change in the market and became one of the best-selling navigators of all time. The GNS 430 was the base on which Garmin Aviation was built and was followed up with the G1000 integrated flight deck in 2004, G600 flight display for retrofit in 2008, G3X Touch for experimental aircraft in 2009, and GTN navigators in 2011. Garmin strives to build avionics with the pilot in mind first, bringing new capabilities to your aircraft that help you plan your flight effectively and arrive at your destination safely. Over 3 decades later we are still working to bring the next generation of avionics built on Garmin’s rich history of innovative design. To that end, Garmin is proud to introduce all of these technologies together in one product, AXIS.

AXIS reimagines the flight display, offering new technologies and an innovative design built from the ground up as an entirely new product. Garmin designed AXIS as an integrated PFD/MFD/EIS with optional built-in IFR GPS, NAV, COM, and a 4-place Audio Panel -- all within a single display unit.

1783519126094.png

The VHF COMM radio offers 10 watts of transmit power, supports 8.33khz frequency tuning and standby COMM monitoring, allowing pilots to monitor a standby frequency while tuned to the active ATC frequency. Pilots can access the flight plan across displays and easily load waypoints or VORs, holds, GPS and ILS procedures and more. The built-in 4-place intercom audio panel includes dual-comm switching with support for one external radio, comm playback and Bluetooth capability for music and phone calls.

What previously required multiple LRUs in the past can now be accomplished with AXIS as a standalone product. Let’s take a look at what separates AXIS from previous flight displays, and how it can transform your panel.

Hardware Overview

The AXIS family of flight displays features three display sizes — 11.6-inch landscape, 8-inch portrait and 8-inch landscape. Each display can be configured as either a primary flight display (PFD) or multi-function display (MFD). Pilots can maximize their situational awareness with full-screen or split-screen options, leveraging a familiar yet modernized user interface.

The Garmin DNA is evident at first glance. The LED back-lit display is brighter with higher resolution at twice the pixel density compared with G3X Touch, offering the pilot crisp and clear data at their fingertips. The landscape touchscreen displays include dual concentric knobs on either side for ease of use based on user preference or turbulence. AXIS is ergonomically designed to serve as an anchor for critical display controls in these same situations. “MENU” and “BACK” buttons are located at the bottom on either side along with an “EMER” button on the left and “Direct-to” button on the right. This button layout will be familiar to G3X Touch users with the main difference being we have expanded the “NRST” button and exchanged it with “EMER” giving each pilot quick access to the emergency information they might need for each phase of flight.

One of the first things you will notice is the speed of power up. AXIS boasts increased processing speed due to a dual core processor that is faster than G3X Touch. That same speed can be noted throughout the flight, optimizing performance and response time which is noticed while panning/zooming the map, updating weather, or other tasks. The system leverages both Controller Area Network (CAN) and modern High Speed Data Bus (HSDB) interfaces, with HSDB offering speedy 100 mb/s for advanced applications like quickly transferring databases between displays.

User interface

AXIS leverages the user interface and architecture from Garmin’s newest line of integrated flight decks, the G3000/G5000 PRIME, to design a display that streamlines access to information while retaining the familiar Garmin ‘feel’, that includes highly responsive touchscreen displays as well as physical controls for quick access to key functions

Apps create shortcuts for the pilot, and provide items you would typically find on an MFD: maps, waypoint information, flight plan, traffic, and more. They can be accessed on a PFD split-screen display or on a dedicated MFD, if configured and equipped.

Garmin incorporated the radial menu from Garmin Pilot to the map screen allowing the pilot to drill down on additional details as needed (e.g., airport information, airspace details, or measuring distances). The radial menu can be placed on the moving map by simply touching the display, the menu will then give you options to learn more details about the underlying aeronautical features. One of the staples of the radial menu includes bearing/distance to information along with the terrain elevation of that location.

Innovative Safety Enhancing Tools

AXIS supports many of Garmin’s award-winning safety enhancing technologies. The dedicated emergency allows pilots to quickly access certain emergency procedure options if needed. Smart Glide™ – a Garmin Autonomí™ technology – helps pilots in loss of engine power emergencies by efficiently navigating to an airport in range and, if the aircraft is equipped with either a GFC™ 500, the system can autoengage to fly the aircraft enroute.

Enhanced Situational Awareness

Important information is easily accessible on the PFD including primary flight data, as well as the horizontal situation indicator (HSI) which can include an embedded map or traffic view.

AXIS includes Widgets which are pilot selectable inset display items on the PFD that are available once enabled from Menu settings. Once set, they provide a compact view of selected information. Widgets can display the map, flight plan, weather, traffic, or nearest items; giving pilots easy access to the information they need. Once enabled, three widgets are displayed.

3D SafeTaxi will come standard providing the pilot with an exocentric view of the aircraft as it taxis; 3D SafeTaxi also depicts taxiway/runway marking, airport signage, and structures giving the pilot extra situational awareness in the airport environment. AXIS will include synthetic vision as a standard feature. Additionally, optional SurfaceWatch™ runway monitoring technology provides visual and aural cues to help prevent pilots from taking off or landing on a taxiway, or if the aircraft is aligned with the wrong runway.

Runway Occupancy Awareness (ROA), is a standard feature if equipped with a compatible ADS-B transponder. ROA is a solution that uses ADS-B traffic to alert the crew of potential runway incursions caused by nearby airborne aircraft, taxiing aircraft and ground vehicles.

Flight planning has been streamlined through AXIS. When paired with a GTN Xi or GPS navigator series, changes can be made directly from the AXIS display.

Connectivity has become vital to avionics in recent years and with built-in Bluetooth and native Wi-Fi AXIS does not disappoint. Database Concierge can be leveraged to update navigation and supplemental databases for each cycle and AXIS can sync that data to compatible LRUs throughout your panel. Flight plan transfers and aircraft flight data logs via Garmin Pilot are another benefit of AXIS connectivity, giving pilots/owners more convenient access to analytical data for maintenance or training purposes. This data can also be shared through flyGarmin integrations like Savvy Aviation or FlySto for further analysis.

New Installation considerations

Your ideal installation depends on what is right for your aircraft and your mission. Which AXIS layout you decide is right for your panel will likely depend on what other equipment you have installed in your aircraft. For example, a new installation might leverage two AXIS displays each with built-in IFR GPS/NAV/COM/Audio Panel, a GI 275/G5 standby, and coupled with a GFC 500 autopilot to greatly simplify your panel without losing functionality. With so many capabilities housed in one display, AXIS keeps the wires inside the box, minimizing the wires behind your panel.

You also may consider a single AXIS base display if your panel already includes a GTN Xi navigator, working NAV/COM radio, and audio panel. For more information about interfaces with AXIS flight display, see our webpage.

AXIS supports up to 6 displays in experimental installations, in many different configurations of Pilot and Copilot PFD/MFD display identities.

Additionally, an HDMI video input on each display allows for live-camera video monitoring.

Upgrade from G3X Touch

AXIS features a streamlined, easy upgrade path from G3X Touch that utilizes most existing sensors, LRUs and similar panel cutouts and existing mounting holes. The AXIS 11.6" display measures 0.15" wider edge-to-edge while maintaining the same panel cutout and mounting hole pattern. The AXIS 8” display maintains the same panel cutout and mounting hole pattern.

The main connector retains most of the same wiring, while specific interfaces will require additional modification and connections. If you have multiple G3X Touch displays they all need to be replaced with AXIS.

So if you have existing LRU's and an existing 750xi - those will work with a base display GDU 116Bx correct? (Yes - just got to this part of the video)

Love the launch video - UX looks awesome!
 
Yawn.

No prices yet.

Spec sheet says the experimental product is vfr, not ifr gps. No com. No nav. No audio panel. I assume the work around is to buy the certified version.

8 inch vfr only regardless.

Literally from the G3xpert post? You have always had to buy a "certified" navigator to be legit IFR.

The main connector retains most of the same wiring, while specific interfaces will require additional modification and connections. If you have multiple G3X Touch displays they all need to be replaced with AXIS.
Would you expand on this, and what it means for those of us with the typical G3X Touch LRUs (GEA/GAD/GSU/GMU/GTP) and external Garmin comm/nav?

Dave
 
Not sure how this will work in an RV-8. Need to get the tape measure out and see if I can fit it in with the required nav and com stuff.

At first glance I think it will. If the foot print is 11.6”.
 
Very exciting! I wonder what you may lose integrating an external com/nav with the GDU116C. This could be a cost savings, if the integration works well.
 
So the 11" display fits in the G3X Touch cutout, and maybe I missed it, but are the exterior dims of the bezel the same?

Laird.

It's 1/8" wider on each side, per the installation manual. Bezel height is the same. The cutout is the same, but the bezel is wider.
 
So my needs would be an AXIS with integrated, but it seems you need to go to the IFR model to get that. So am I wrong in thinking for a VFR setup I would get the basic AXIS and then a com (245/R) and then just use the built in GPS? And yes I will have a 2 axis autopilot.

Thoughts?
 
I feel like for the experimental side on and IFR aircraft this does nothing but give you a bigger screen? What am I missing here?
A lot fewer boxes and a lot less wiring, if you're going dual screen full IFR. My -7 has dual 10 inch GDUs, a 625, and a mile of rat's nest wiring behind the panel. I can see how this might not seem like that big a deal for single VFR and/or 8 inch only installs, but just from watching the video it seems even more user friendly and the cost isn't significantly increased over the 12-year old G3X, so you might not want to upgrade necessarily but it's an easy choice if you're in the market for new now.
 
Seems like the missing component is a nav/com/xpdr/adsb remote mount everything box, with something like a single HSDB connection.

That and an experimental version with just VFR/Comm. That would be in high demand, especially if it fits the 8” version.
 
So if you have existing LRU's and an existing 750xi - those will work with a base display GDU 116Bx correct? (Yes - just got to this part of the video)

Love the launch video - UX looks awesome!

That is correct. You can control the flight plan of the GTN 750 Xi, from the GDU 116Bx as well. This does require the addition of an HSDB connection between the GTN Xi and the AXIS display. This is also true for GPS 175, GNC 355, and GNX 375.

Would you expand on this, and what it means for those of us with the typical G3X Touch LRUs (GEA/GAD/GSU/GMU/GTP) and external Garmin comm/nav?

Dave

Altogether, 33 pin assignments remain unchanged between the G3X Touch P4X02 connector and AXIS flight display J1012 connector. Nine pins are assigned functions in J1012, that were unused and reserved for future use in G3X Touch. Up to eight pins may require reassignment, mainly to support the new HSDB architecture. Your CAN LRU's will remain unchanged.

Not sure how this will work in an RV-8. Need to get the tape measure out and see if I can fit it in with the required nav and com stuff.

At first glance I think it will. If the foot print is 11.6”.

Here is an installation we completed in one of our teammates RV-8:
1783527632686.png
So the 11" display fits in the G3X Touch cutout, and maybe I missed it, but are the exterior dims of the bezel the same?

Laird.

GDU 116 was designed to occupy the same instrument panel opening used by the G3X Touch, GDU 46X. GDU 116 uses the same mounting hole locations as the GDU 46X. However, the bezel of GDU 116 is 0.075" wider on the left and right sides., than G3X Touch. The top to bottom bezel dimension is unchanged.

So my needs would be an AXIS with integrated, but it seems you need to go to the IFR model to get that. So am I wrong in thinking for a VFR setup I would get the basic AXIS and then a com (245/R) and then just use the built in GPS? And yes I will have a 2 axis autopilot.

Thoughts?

You can use a AXIS Base display and a GTR 205xR for a basic VFR installation. This provides a remote mounted COM radio, with built in 2 place intercom. If two COM radios are desired, you would need a second GTR 205xR, and a GMA 245R audio panel to switch between them.
 
@g3xpert

Thanks for the above response

Sorry for the possibly dumb question as I am not really Garmin literate coming from a Dynon panel. My Dynon radio allowed me to be on “dual” so I could communicate on “fingers” and monitor the local radio frequency. Would I need two 205R’s to do this with the Axis or even the G3X?
 
For a new build, I have GNX375 on hand.
Would you recommend keeping that and buy 2 x GDU116Bx + Audio Panel + Nav/Com + Com?
Or just sell it and buy your IFR Example, but would need to add a second Com and Transponder.

also - your list price says the GDU116Bx is $5600 but your examples say $4980, which is accurate?

Edit: I may have answered my own question @fl-mike called it above. These are just napkin numbers i've pulled from websites and may not be complete, but it sets a clear winner.

If other panel mounted units are within 1/8" of the current GDU 46X, the instrument panel may need to be modified to accept the new GDU 116 to accept the new GDU 116."

Yep. I've got two GDU-460's side-by-side in an Aerosport "EFIS Instrument Panel." I don't think there's an extra 1/4" available, even if having a new insert cut.

Cutout.jpg Bezel.jpg
 
I have a panel cut and mounting brackets complete but have not bought avionics or done the wiring yet. I believe I can simply switch my two planned GDU460s with two of the new basic screens. It will be compatible with the rest of my planned avionics, right?

Two new 11" screens plus the following:

GMU11
GSU25 x2
GEA24
GMC507
GSA28 x3
GTN750Xi
GTR205X
GMA245
GTX45R
GAD27
GHA15

I can eliminate the planned GAD29 and instead wire an Ethernet connection from the GTN to the new screens?
 
If starting from scratch, building a VFR panel with the option of adding a 375 later, is there any reduced wiring to the LRUs due to HSDB addition, or is it the same connections/pinning connectors as with the G3X?
 
If one were to go all out with three of the larger screens across the panel, can you get by with only the pilot side having the certified IFR GPS but still control it from co pilot side?

The integrated GAD29 is built into the GDU116C / NC versions, not the base model. If you are retaining the GTN and upgrading the EFIS from a GDU460 to a GDU116BX then you will keep the GAD29 but will still need to connect the GTN and transponder to the Axis display.

Ah...so I have a 175 sitting new in box that I have not gotten around to adding to my RV-12is. I was hoping that going to a base model Axis would simplify that install a little bit. Based on this, with the base model the wiring actually ends up more complicated since all the GAD29 has to stay plus the HSDB to axis.

That's unfortunate and curious, but I guess I understand the need in order to support the integration.
 
120W - 310W @ 1090MHz -- keep that in a faraday cage behind the panel, or under the floorboards.
I don’t disagree…I’m talking more about making sure folks understand an all-up system cost…. And its not just “a transponder is a transponder, so its break-even, because if you get a 375, you get a transponder for $5K and an IFR Navigator for only $2K more. So there is a lot of penciling-out to do…..
 
Looks like the new vfr display with a GNX375 and GTR is still the value leader. That it fits in the same hole makes me happy I deferred my display purchase.

Absolutely, for a value IFR package, a navigator like the GNX 375, along with a GTR 205x(R) is still a great value option.

For panels utilizing GTN Xi Series IFR Navigators, the integrated certified IFR AXIS displays become a closer price comparison, while greatly simplifying the installation.

The monitor feature on a Garmin radio will allow you to listen to your standby radio frequency, while keeping hte primary frequency active and available for primary communication. This is true for a GTR 205R or a GDU 116C or NC.

For a new build, I have GNX375 on hand.
Would you recommend keeping that and buy 2 x GDU116Bx + Audio Panel + Nav/Com + Com?
Or just sell it and buy your IFR Example, but would need to add a second Com and Transponder.

For value IFR installations, the GNX 375 is a great value. The GNX 375 and AXIS Base display are tightly integrated, with the ability to modify the flight plan of the GNX 375 from the AXIS display. At this time, GNX 375 ADS-B Data does not enable Runway Occupancy Awareness in AXIS, a GTX 345/45 is required for this function.

Opting for the Integrated GDU 116NC route would greatly simplify the installation, with less wires to run behind the panel and fewer structural modifications to complete.

"GDU 116 was designed to occupy the same instrument panel opening used by the G3X Touch, GDU 46X. GDU 116 uses the same mounting hole locations as the GDU 46X. However, the bezel of GDU 116 is 1/8" larger than a GDU 46X on both the left and right side. The top to bottom bezel dimension is unchanged. Installers should plan GDU 116 upgrades carefully if the current GDU 46X is placed within 1/8" laterally of other panel mounted units. If other panel mounted units are within 1/8" of the current GDU 46X, the instrument panel may need to be modified to accept the new GDU 116 to accept the new GDU 116."

The AXIS display's are 0.075" wider on each side. We apologize for the confusion on this aspect.

I can eliminate the planned GAD29 and instead wire an Ethernet connection from the GTN to the new screens?

Only the GTN Xi and GTX 45R would require a slightly different wiring architecture, with the addition of the HSDB network. Everything else on your list remains compatible with the wiring architecture used in G3X Touch. You can eliminate the GAD29, however it is optional to retain ARINC 429 from the GTN Xi to the AXIS system, to provide navigation information to a connected G5 in the system, in the case that the primary display fails.

If starting from scratch, building a VFR panel with the option of adding a 375 later, is there any reduced wiring to the LRUs due to HSDB addition, or is it the same connections/pinning connectors as with the G3X?

The HSDB interfaces will allow an easier upgrade to the GNX 375 at a later time. Connectors and pinouts are vey similar to G3X Touch with some minor modifications. This can be foudn in appendix F of the AXIS EAB Installation manual.

Alternatively, you could install a base AXIS display, with a remote mount GTX 45R transponder now, and later add a GPS 175.

If one were to go all out with three of the larger screens across the panel, can you get by with only the pilot side having the certified IFR GPS but still control it from co pilot side?

Yes, using the HSDB network, the flight plan is controlled from any AXIS display in the system, regardless of display variant type. Navigation information from the NAV/COM display variant will be available to all AXIS displays in the system.

Ah...so I have a 175 sitting new in box that I have not gotten around to adding to my RV-12is. I was hoping that going to a base model Axis would simplify that install a little bit. Based on this, with the base model the wiring actually ends up more complicated since all the GAD29 has to stay plus the HSDB to axis.

That's unfortunate and curious, but I guess I understand the need in order to support the integration.

The GAD 29 can be eliminated in this installation. The GPS 175 can connect to the AXIS display using a 4 wire HDSB connection only. You can retain the GAD29 for increased system redundancy, as it provides a backup path in the case of a failure.

also - your list price says the GDU116Bx is $5600 but your examples say $4980, which is accurate?

Edit: I may have answered my own question @fl-mike called it above. These are just napkin numbers i've pulled from websites and may not be complete, but it sets a clear winner.

The display pricing table is List Price. The price listed in each example is the Minimum Advertised Price. You will need to discuss pricing details more in depth with the Garmin dealer you order your equipment from.

Thanks,
