Hello Johan,

Lateral and vertical navigation may be displayed either on the G5 PFD or on the dedicated HSI page.

Here is a link to the current G5 user manual (rev B). It contains numerous images of navigation data displayed on the G5 PFD and HSI pages: http://static.garmin.com/pumac/190-02072-00_B.pdf

I'm installing two G5, one as a ADI and the other as HSI..They will be connected to a Garmin 650 then to a GAD 29. Can they be wired to both G5 while only using one GAD 29..

Thank you!

Hello Jim,

Yes, that configuration is definitely supported. A wiring diagram showing this setup will appear in the next revision of the G5 installation manual, which should be available later this month. If you need an advance copy of the diagram sooner, drop us a line at the email address below and we should be able to fix you up.

Matt,

I am planning on replacing my Trutrak Gemini PFD, my Narco 122 VOR/ILS and the GTR 200 with the following:

- Garmin G5 with backup battery receiving the RS232 input from my already installed Aera 660 GPS.
- Garmin GNC 255A
- GAD 29 Interface
- Garmin GTX 335 Transponder (down the road a bit) to replace my Collins TDR-950

When the GNC 255A has an ILS frequency tuned how does it display on the G5 if interfaced via the GAD 29? I know the G5 has a flight director display (dual and single cue) but the manual doesn't specifically show what flight director guidance is available on the G5 for an ILS approach. It shows a dual cue flight director display when tied to a GPS source but not specific on what you see on the G5 with an ILS tuned.

- What do you get for a flight director on the G5 and/or can you select between dual cue and single cue for an ILS?

- A previous post mentioned that the G5 RS232 output can be sent to compatible transponders as the altitude encoder. Does this eliminate the need for ANY other altitude encoder? I plan on a future upgrade using a Garmin GTX 335 (with GPS) as an ADSB-out solution.

Hello Oly - Thanks for your interest in the G5.

The GNC 255 has an RS-232 output, so you would not need the GAD 29 ARINC 429 converter for your proposed installation. A direct RS-232 connection is all that would be required.

Please note that the G5 does not support interfacing to multiple navigation sources. So with your proposed equipment list, you would need to decide if you want to configure the G5 to display navigation information from the aera 660 or GNC 255, since two different navigation sources are not supported. Or you could install two G5s if you want to see navigation data from two different RS-232 sources.

The G5 displays navigation data (GPS, VOR, or ILS) either on its dedicated HSI page, or via horizontal/vertical deviation indicators on the PFD. You can see images of this in section 2.8 of the G5 manual: http://static.garmin.com/pumac/190-02072-00_B.pdf

The G5 flight director is part of the automatic flight control system, which requires a GMC 305/307 mode control panel and GSA 28 autopilot servos. Without those components you would not see a flight director, only the basic PFD display and horizontal/vertical deviation indicators.

Yes, you may use the G5 as the altitude encoder for your GTX 335, and no other altitude encoder would be required.

Hi, what happens if you have a G5, GMC 305/307 driving a Trutrak Vizion 385 (either standalone or as part of a G3X Touch solution)?

Have you added support for configuring the GMU22 magnetometer in a standalone G5 installation? If not, is it on the short term roadmap?

Thanks.

Hello jeffk,

The G5 does not support integration with third-party autopilots. In a standalone G5 installation where a third-party autopilot is installed, a GMC 305/307 would not be used. You may still connect your third-party autopilot to your navigation source and use whatever features it supports.

In a G3X system installation with GDU displays + GMC 305/307 + G5 + third-party autopilot, if power is removed from all GDU displays the third-party autopilot would still provide its own built-in functionality. In this case the G5 would be a standby flight instrument only. This is no different from an existing G3X + third-party autopilot installation with any other standby flight instrument.

We are aware of interest in a magnetometer solution for standalone G5 installations, but that's all we can say at this time.

Matt,

A lot of us thought the G5 was going to have a flight director enabled for shooting ILS approaches totally within the G5. Granted that can still happen but with just course deviation indicators it's really just a raw data approach and hard to justify the cost & time to upgrade when I have that capability now with the Narco 122. I know a lot of other RVs have pretty basic Nav displays but for the price point the G5 would be a hot seller with a flight director ILS.

Maybe there's more to it but can't the software within the G5 at least produce large ILS needles in the center of the display similar to the dual cue flight director instead of just tiny raw data deviation indicators on the side and bottom of the display? Even if it's still not a flight director (would be nice if it was) it would be far better than raw data CDIs.

Any long term plans for this? If so I am waiting to write some checks,
Oly

Maybe you should look at the new GRT Sport EX, with inverted V FD included.
