Generally most all of the experimental AP's on the market today will smoke the STEC in performance. These modern all digital AP's and their servos are simply amazing to experience compared to the old school rate based units.

As for your other questions: It depends


Some AP's like the TT Sorcerer can couple to both GPSS/GPSV, NMEA and NAV Radio signals (VOR/GS/LOC) others that TT make can only talk NMEA or GPSS/GPSV.

Some EFIS units connected to the proper TT AP can transfigure the NAV radio signals and convert them to GPSS/GPSV that the TT AP can understand and be able to couple to VOR/GS/LOC signals.

Then there is the AP's that can be built into the modern EFIS systems. Feature sets vary between EFIS makes and they are constantly updating their capabilities so it is hard to keep up with which one can do what.

The Garmin G3X AP can couple to it's VNAV just fine. It can also pretty much couple with any other navigation source that it supports. I imagine this will not change when they add the ability to set your own glide angle.

Yes of course. Been doing that for many years.

You can use either the internal AP or an external AP using any of the many internal nav sources or external nav sources including analog types (+/-150mV signals).
To simplify operation our current systems assign a priority to equivalent nav sources. Say you select "en-route GPS navigation" - this would be anything from a direct-to or a route/flightplan. If you are doing this using the internal GPS it will be used UNLESS it gets en-route navigation information from an external source - in this case the external gets priority (typically a Garmin source). In case of multiple internal or external sources - these are again assigned a priority (for example should you have a SL30 Nav plus a G530 and both are giving VOR - then the systems picks the G530 as it has a higher priority).
The same goes for any other nav mode (VOR, ILS, heading bug...).

This keeps things simple despite supporting a plethora of nav sources and modes.

7 months have past since the above message from Garmin. Any development on giving g3x the capability that is present on g1000 (and that grt, mgl and afs already have), to descent to any waypoint with arbitrary bearing AND arbitrary glide angle, both kept constant by the autopilot?

Matt, any progress on the "investigation" of providing this ability with the g3x?

18 months have past since the above statement from g3xpert. Any update on this capability for the G3X? It's just a question of software update, a developer familiar with the G3X system would take 1h to do the job. It's a capability that most uncertified EFIS have and the G1000 has (I use it in EVERY VFR flight on my G1000).

Question Documentation for GRT custom synthetic approach?

The answer now, is, yes, you can.

Below are file details to make a synthetic approach in the GRT Avionics EFIS to any landing site you want, anywhere in the world.

<GRTUserDB>
<Airport ident="UDBEX3" lat="42.900000" lon="-85.900000" elevation="604" name="USER DATABASE EXAMPLE 3">
<Runway surface="ASP" length="3000" width="50" >
<RunwayEnd ident="09" lat="42.900000" lon="-85.904000" elevation="606.0" />
<RunwayEnd ident="27" lat="42.900000" lon="-85.896000" elevation="602.0" tdze="602.67" dispthr="200" dispthrelev="602.27" lights="Yes" />
</Runway>
</Airport>
</GRTUserDB>


For more details about Synthetic Approach to Your Backyard Strip go to

Have fun, fly safe!

...above, beyond.
Anyone know where to find the documentation on this. The link is broken. I am reasonably sure that the missing piece of information is the expected file name.

Thanks in advance!

Cheers, Sean

As has been mentioned already, Darwin will get involved if folks are not doing things correctly.
The problem with letting Darwin sort things out is that Darwin and attornies are best friends. Once Darwin steps in the attornies are sure to follow and that ultimately has a negative effect on us all.

Cool All we want are the facts, ma’am

My bad, I should have noted that the controversy has been beaten into some kind of submission over the last 136 posts and hoping to return to the intent of the OP. Any information or documentation appreciated. I've reached out to GRT but the brain trust here is often faster.

Cheers, Sean

Sean - the "how to" is now documented in the baseline GRT operator's manuals.

Despite the dire warning issued above, the SAP is a very handy thing to have available. Not to permit an instrument approach into a field that doesn't have an instrument approach, but as additional guidance and a cross-check for the visual approach you're making to that field.

Default GRT - How to...

Thanks Canadian_Joy! For those who may follow:

User databases are loaded through the SET MENU, Display Unit Maintenance, Database Maintenance, Update User Database function. Upon activating the function, the EFIS will display a list of files and folders on the USB flash drive.

Cheers, Sean
