Frugal Glass Panel?

dmat · #1 10-09-2017, 10:04 AM

OK...so I am going to go glass to convert my steam system to glass IFR.

What's the best and most frugal way of making my ship a glass IFR ship?

I currently have:
- GTR200 comm
- Garim G5 (not installed, just ordered) to replace steam
- Trio EZ-pilot

I was thinking:
1) Garmin g3x (used non-touch)
2) WAAS GPS.... what would you suggest? garmin 625? 430w?
3) another Nav/Comm?
4) VOR head?

I am open and prefer to go used due to cost savings.

Thanks,
D

I am in the process of planning an IFR upgrade my panel, which is based on a GRT Sport SX. GRT has some excellent products, so definitely check them up and they can steer you in the right direction.

I also have a used Dynon D10 ($500 at the time) as a backup instrument, with it's own backup battery. You could probably find a D10A on the used market very affordably if you wanted a backup unit.

I am currently torn between adding a Val Nav2000 ($1300) so I can at least shoot the occasional ILS, or sucking it up and going with either a GPS400W or GTN625. I already have the tray for a 400W mounted.

If you already have a reliable Comm radio, and don't need/want a Nav radio, a GPS400W paired with your EFIS is all you need. You can find them used for under $6k. But, if you are going to spring for a new G3X, you can get a new GTN625 for the same or less than a used 400W as a part of their special package deal. Personally, this drives me nuts because I would buy a GTN625 tomorrow for $5500, but since I'm not also buying a G3X, I can't. And I'm not going to pay $8-9k for one. Maybe I can find somebody buying a G3X who doesn't want a GTN625...

Lastly, I don't know if you have an autopilot or not, but I am in the process of installing that now, before adding any IFR upgrades.

Stick with the 625-the ground based stuff will likely soon be a thing of the past for GA. Add a 345 transponder that will make you 2020 compliant and allow weather and traffic to show on the G3X. Add in a heated pitot, a backup portable GPS, a two axis AP, and you've got a very solid platform.

"...best and most frugal..." is a classic contradiction in terms! Terry's suggestions are more the former.
Do you need ADSB-out (Phila or NYC class B, or over 10,000'?)? What kind of shape is your transponder in? If you have a good mode C transponder, consider the Echo UAT. If you need a new transponder, look at the Trig TT22.
Older non-WAAS gps' are cheap, but then by law you need a VOR. If my home field had an ILS I'd consider this. (Look at a used SL-30, still the best nav receiver ever built. No vor head, pretty much any efis will display the data). The downside is that these gps boxes are getting old; if nav-data support goes away, they become worthless. I would bite the expensive bullet and go for a WAAS gps (and a $400 handheld VOR, and make sure I could use it if the gps failed, to get into my alternate). Unfortunately used prices for a 400W are still pretty high, and you also have to subscribe to database updates. Good news is the 400W can do double-duty, serving as the approved gps source for either the Echo or TT22 ADSB-out.
Does Trio make a vertical module you can add to your existing autopilot? Or can a new Trio Pro head drive your existing servo? The GRT HX integrates nicely with the Trio Pro, for what that's worth. I think the HX's are starting to show up on the used market, as people upgrade to bigger HXr units. Everyone likes what they have, I'm a GRT fan.

Hello D,

It is hard to beat a G3X system, but since you have ordered a G5 and are thinking along those lines, you could also consider something like this.

Something else to consider is a big GDU 37X or GDU 4XX display mounted in front of the pilot alongside the G5 instruments. These displays will automatically receive the flight plan or procedure, including all curved paths and holding patterns, from the GNS/GTN unit over RS-232 and give you a bigger and more conveniently located display that can supplement the GNS/GTN display in the radio stack.

The GDU can also connect to a wide variety of ADS-B and SXM traffic/weather receivers (GTX 345, GDL 51/51R/52/52R, GDL 39/39R) and provide that powerful capability as well. The GDU 37X has 3 RS-232 ports and the GDU 4XX displays have 6 RS-232 ports to provide an almost unlimited capability to interface with important devices.

The new V4.00 G5 software that will be out soon even supports dual navigators (with source select provided on the G5) so in this example the GDU 470 could be GPS1 and the GTN 625 (for example) could be GPS2 and either could be used to fly and couple to the optional autopilot.

Thanks,
Steve

g3xpert,
The Garmin part numbers and letters are like a foreign language. A newbie has no idea which components are required. It would be helpful to those shopping for avionics if there was a list of part numbers with a brief description and price for each. Ideal would be, say, four lists with a total price for each. For example:
Complete deluxe IFR system.
Minimum IFR system.
Deluxe VFR system with traffic and weather displayed.
Minimum VFR system.
Thanks

AMEN Joe...AMEN!

Impressive presentation.

Joe if you want to go this route and install it yourself to save money, this is going to take research on your part. There is quite a bit of legwork involved. Otherwise drop it off at a shop, tell them what you want, then pick it up and pay the bill in a week.

If you want to see different systems look in the g3x install manual and it shows how to wire up the systems and kind of what is involved. Aircraft spruce has the prices listed out for all of the systems and allows you to build what you want.

I do installs of g3x systems on the side and I'm covered up for a few months after I get back from deployment. It supports my flying habit and gives other people an option to get glass installed at a fraction of the big dealers. Look around in your area and ask around as I'm sure there's many more like me out there that can lead you down the right path if you aren't willing to do the research on your own.

Hey Timber,

No need to jump on Joe. This was a thread started by myself and if you want to jump on anyone, feel free to jump on me.

But I will say, Joe made a good point, it would make it easy for me if the garmin dealer who posted to give me a rundown as it would make my decision easier and would probably lean me towards purchasing. it's all about customer service.
