GDU 470 vs GDU 460, pics please

FORANE

Well Known Member
Considering installation of a G3X. Panel space is limited. GDU 470 would easily fit. GDU 460 would require major surgery.

Searching this site and elsewhere online I find requests for pics of the GDU 470 in split screen PFD/MFD but a scarcity of pics. Plenty are available for the GDU 460.

Clearly, with a GDU 460, one can view the PFD and take your pick of any: moving map / change frequencies / modify flight plan / etc. Can one do this with a GDU 470 without losing the PFD when doing so? What does it look like?

If I only have room for one GDU 460 or GDU 470, will I be regret choosing the GDU 470?

Hello Forane,

You may know that we don't recommend a single 7" GDU 450/455/470 display.

A single 10.6" GDU 460/465 display is excellent.

Thanks,
Steve
 
It is hard to beat a G3X Touch system, but here are some additional options for those with a narrow instrument panel.

Single GDU 470 standalone MFD with single or dual G5 units and autopilot.

EMS

I like the limited set up that Steve describes but you still need an EMS in this case (I assume since no instruments are visible). The single 460 gives you everything in one screen. My 2 cents.

Hello Darin,

You are correct that these G5 examples do not include engine instruments, which is normally what pushes people over the edge to get a full G3X Touch EFIS.

Thanks,
Steve
 
Is there not an option to display engine instrumentation across the top of the GDU470 as I can on my GDU370?

Yes, when the GDU 470 is installed as part of a G3X Touch system. Here is one example system.

If a person has room for 2 7? screens in portrait mode, they?d also have room for a single 10? screen in landscape mode.

Can a person accomplish everything on a single 7? screen?albeit smaller than a 10??
 
Or maybe a GDU470 as the PFD with the engine instruments on it, and a 660 for the map?

That's not a bad idea, Walt. I like it.

For a VFR aircraft the Aera 660 could get the flight plan from the PFD over the wireless link.

For an IFR aircraft, both the PFD and Aera 660 could get the flight plan from the GNS/GTN over MapMX (RS-232).

The single GDU 470 PFD has a Split/Full button in the upper left to split the screen and expose the MFD pages including map and flight plan. Meanwhile, the Aera 660 would be a full-time MFD with traffic/weather.

I think this is what you're looking for. I agree, not easy to find at all.

As you can see the PFD section is quite compressed, probably why Garmin don't recommend this. The difference with the 370 appears to be in the amount of info displayed across the top of the screen. With a Garmin Comm and transponder in the system, there would also be those fields.

I wonder if engines were displayed in the MFD section, if the engine strip would be removed making more room for the PFD?

In my opinion this single screen would be ok for VFR, but I wouldn't want to fly IFR with it.

Yes Ed, that is what I was looking for. Thank you. Up til now, I did even know if it was possible to display the PFD in split screen with say comm or flight plan, etc.
I agree the PFD in your pic is so compact it would be difficult to realistically use IFR. But, if one were to never display engine data on the GDU 470, it might work.
I wonder if engines were displayed in the MFD section, if the engine strip would be removed making more room for the PFD?
Is this possible Steve?
What about the ability to never reduce the size of the PFD at all; is there an option to customize the data fields on the top of the screen or only display them in the MFD section?

Steve I have a couple questions regarding this setup (460 landscape, GTN 625 in center stack, Aera 660 on passenger side for IFR charts and backup gps) as I am considering it:

Should the optimal setup be a 460 landscape with a GDL 52r going to a 660 to get the weather and traffic so that it displays on both screens via 232? Or would the 460 landscape with xm option be the way to go with the Aera 660 (660 already provide weather and traffic via G3X Bluetooth, so the 52r not needed?)....I'm planning either a 45R xponder or another option, but assuming for ads b in and out that would be the best option.

As far as the 660....is the screen large enough and ideal to be MFD for weather and charts,etc? Is Garmin planning on a larger screened 660? I could go 796, but it doesn't have the same G3x integration correct?

I initially was planning duel 10" screens, but a part of me thinks it's overkill (maybe not for the passenger), and I like the back up battery redundancy that the 660 offers. Plus I'd have a G5 backup as well.

Thx for the feedback in advance.

Here are some additional pictures of a single GDU 470 installation. The top data rows can be configured for one or two rows of data fields. If you can get by with one row of data fields, it leaves leave more room for the PFD/MFD information.

Using a remote mount COM radio or transponder also places additional demands on this limited display area.

The GDU 465 doesn't share SXM weather with an Aera 660 or anything else, so it would be better to install a GDL 52R which can share ADS-B traffic/weather plus SXM weather/music with up to 2 wired and 2 wireless display devices.

As far as the 660....is the screen large enough and ideal to be MFD for weather and charts,etc? Is Garmin planning on a larger screened 660? I could go 796, but it doesn't have the same G3x integration correct?

I initially was planning duel 10" screens, but a part of me thinks it's overkill (maybe not for the passenger), and I like the back up battery redundancy that the 660 offers. Plus I'd have a G5 backup as well.

Thx for the feedback in advance.

Whether or not the Aera 660 display is large enough depends a lot on where you mount it. A lot of customers mount it right in front of the pilot next to a pair of G5's like shown above and find it is awesome, but many also prefer the larger size of the Aera 795/796. The Aera 795/796 has the same wireless capability to share flight plans with the G3X Touch PFD as the Aera 660, so it is also a good choice.

I have a tandem homebuilt aircraft with a very narrow instrument panel, so the Aera 660 is a perfect size for me and significantly enhances and backs up the single GDU 470 in the panel. I have a GDL 52R connected via RS-232 to both the GDU 470 and the Aera 660 and love it. The Aera 79X is much too large for my application.

Thanks,
Steve

This is one version of a new panel I'm hoping install in my newly-acquired RV-3. I'd use a remote transponder and comm. I don't really care too much about having a map display on the GDU470 because I'd have the aera 660 for that.

I'd want autopilot mode annunciation, engine instruments, and transponder/comm information on the 470. Traffic, wx, charts, map, etc. could be on the aera.

Thoughts?

Thx Steve for that input. One more question on which transponder makes most sense with the 52/R then:

The way I see it is if I go with a GDL 52 it takes care of ADS B "In" & XM to multiple screens, then all I would need is a GTX 35R (ADS B "OUT") to have the whole shabang?

Alternatively I could go with GTX 45R (IN & Out) and then use the 51R (XM only)

Costwise the first option is cheaper though...

Correct?

Sorry didn't mean to highjack the thread but is somewhat related so maybe will help others...

Hello Ed,

We would agree that the GTX 35R is a good transponder choice if you have a GDL 52R.

The only advantage to having a GTX 45R is if you want a GTN 6XX/7XX to also receive ADS-B traffic/weather. The GTX 45R will do that, but a GTX 35R with GDL 5X cannot.

Most of us don't feel it is too important for the GTN to show traffic/weather in a G3X Touch installation, but some feel differently.

Thanks,
Steve

Hello Rod,

If you have remote COM and XPDR with a single GDU 470 display, it reduces the number of available data fields down to 3, but otherwise works well. Your Aera 660 can have up to 8 data fields on the map page, so perhaps this GDU limitation is not a big deal.

If you move your switches up above the GTN and install a GTR 200 COM radio, you can free up display space and have up to 4 data fields on the GDU 470.

There are many reasons for wanting a panel mounted COM radio instead of a remote mount, and having a dedicated volume knob plus having a fully functioning COM radio even if the GDU fails are two reasons.

Thanks,

Thanks for the input, Steve. I like the idea of redundancy re: tuning the comm if the screen goes dark, so I may have to re-think the GTN625 thing. It may be worth the extra $$ for me to go to a navigator with a built in comm.

It?s only money, right?!?

I appreciate this thread because it?s already prompted me to consider the 660 when I hadn?t even thought of that before.
