I have both on the G5
I hope you can still get and take advantage of an IR with your setup. I understand your disappointment.
So you have your GPS CDI on the G5 and the VLOC on the mechanical CDI ?
@Wingover avionics always get lots more pricey than one thinks. Some say it’s the same price for install than what the device costs.
Your avionics is working but you cannot fly GPS approaches, correct?
What about keeping everything as is but installing a simple device like the 175 from Garmin additionally for having the ability of doing GPS approaches? Without touching anything else.
Hand flying the approach isn’t that hard. I still do it every approach because it’s fun.
I know it’s not perfect. But when you open the can of worms it’s an epic journey to a new panel. I’ve seen so many projects. Something goes wrong. Something breaks. And then who’s there to blame? Old parts tend to make trouble when you start to change something. It’s incredible how few things you can install for insane amounts of money. And then how often will you use your plane to see a return of invest?
Just my 2 cents because of the very low cost limit that you settle. I’d say it’s unrealistic to achieve it in another way.
If you later go for the GFC500 you will have to change lots of things anyhow.
The goal is to finish my CB-IR rating and get to know the plane since it is new to me. Long term thinking is maybe go with a GFC500 although my current AP work well.
I’m going to wait until my annual in 4 motor and see what I think about it all before buying anything.
You‘re welcome. I‘m a bit bummed I didn‘t catch this earlier when we discussed the different options…
Depending on what your further plans are and how well your AP works, you could go ahead with the CDI as a temporary „fix“ and then decide on the middle- to long-term course of action…GI275, GTN650 or GFC500.
PS. If you need another CDI to keep both NAVs active, I think I still have a KI-204 in the basement that I could part with.
Thank you for your help!
Yes, that was what I was referring to. The GNC255A can connect to most of the CDIs that are around.
That would be an option, unfortunately to comply with the Garmin STC, you would have to actually remove the connection from GNC255A to the G5, so no way to even display the ILS for hand-flying, outside of install a NAV2 indicator
When you say NAV2 indicator, do you mean mechanical CDI? I do have one with glide slope that can be used.
How was the GPS 150 wired up until now? Did you have the ability to fly “NAV” with it?
The absolute cheapest way to “solve” this problem is by wiring the GPS 175 to G5 and AP, wiring a NAV2 indicator to the GNC255A (you might already have one in the panel), and sacrificing the ability to fly coupled ILS. This is not a huge problem at least around central Europe since most any place that has an ILS also has an RNP approach, but of course it hurts. You would only be able to hand-fly the ILS.
