Sheriff23 Posted July 18, 2023 Report Posted July 18, 2023 My 67F is in for the panel upgrade. I am installing a G3X touch, 650xi, and a GFC-500! I have a KX-155 that I was planning to retain as a standby Comm/Nav with CDI, but I am considering other options One is a GTR-20 for comm only. Has anyone gone down to single nav when upgrading their panel? I am not aware of a remote nav for the G3X. Any inputs from people who finished similar panel setups is welcome! Here is my current panel: Now they’ve started!!! The final panel will look similar to this 3 Quote
Pinecone Posted July 18, 2023 Report Posted July 18, 2023 Why not keep your 430 for your second nav/com? It gives you Comm, GPS, and VOR/LOC capability. Quote
Aerodon Posted July 18, 2023 Report Posted July 18, 2023 Have a serious look at a SL30 or GNC355 for your second fav com. I believe the serial interface will work with both the G3X and the G5. Aerodon 1 Quote
hubcap Posted July 18, 2023 Report Posted July 18, 2023 I put in a GNX 375 as the back-up navigator to my GTN 650Xi. The 650 cross-fills your flight plan automatically to the 375. Quote

The 650 doesn't have connext, but can accept it from the GNX. And that functionality just got put in to the 650 recently. Quote

Two GPS's, two radios, one nav. I've got a 345R connected to the 650xi to free up some panel space. 1 Quote

I was looking at switching to a 345R for panel space but wasn’t sure I wanted to spend the extra money for something truly not needed. Quote

Expand I have a terrible mindset of "screw it I'm already dropping $ for all of this, what's a little bit more to free up the panel?..." It in fact, did not free up the panel. Headset jacks were above our heads which I hated. So, moved them to the empty slot until I get the vac system removed, and replace instruments with a 275. 1 Quote

If the primary gps (650) fails, you want either a gps or nav (ils) remaining to get you down. and either way, you want two comm radios. Edited July 18, 2023 by Ragsf15e 1 Quote

If I'm IFR and the 650 fails, I'd just try to get VFR or land asap with the 355 for a GPS airport. I'll always keep that in mind while planning. 1 Quote

OR75 Posted July 19, 2023 Report Posted July 19, 2023 Isn’t having 2 panel GPSs an overkill ? any modern WAAS GPS has enough ports to connect to indicators , A/P, ADSB , FF , …. my second map GPS is a tablet ( iPad) . Easily upgradable , very cheap to update the database , large screen size of my choice, take home for planning , at 1/10th of the price 1 Quote

That is why I added the 2nd GPS. I have had a failure in IMC in the past. One is none. Two is one. 1 Quote

That said, my second GPS has functionality I'd need anyways, so it's a good safety of mind. The 355 (which I have) has Connext, to push and pull information. It's also got a comm, which I'd have needed anyways. Mechanic sent me a picture of the work in progress so you can see the 650 and 355. Note on the non-ideal headset jacks: The headset jacks there are temporary until the EDM gets upgraded to a 900. They can't go by my knee since I'm pretty tall and bump that area, so I'll just have them extended and zipped to the bottom of the panel, routing to the pilot side and out of the way. There was apparently not a single inch on the panel that was free to use. He video-called me to prove it to me. 2 Quote
TheAv8r Posted July 19, 2023 Report Posted July 19, 2023 @Sheriff23 Yes, I went from 2 Navs down to 1 Nav on my panel upgrade (KX-155 to a Garmin GTR 225). Logic was, in the last 3 years, flying 150hrs a year, I had not actually used my Nav 2. I asked a bunch of my flying buddies when the last time they used Nav 2 was... none of them could recall it. So I ripped it out and saved myself a couple grand on the GTR 225 vs the 255. No regrets, have yet to need a Nav 2 1 Quote

Going through different cases: - satellite signal is down: 2 panel GPS + iPad ... all down .... Turn to VOR navigation. - one panel GPS unit fails (antenna or whatever): other panel GPS still works and iPad still works - aircraft power failure: 2 panel GPSs down, iPad still works not sure how to assign a probability of occurrence to those cases 2 Quote

I will have 5 when my panel gets done. G3X VFR GPS GTN-750Xi GTN-650Xi (have it and not enough saving to swap down) AERA 760 (dock on right panel) iPad running FF or GP 2 Quote

The GNX 375 was relatively inexpensive as a percentage of my panel upgrade. Quote
