If you have the stomach to, do take a look at the GI-275 instead of the G5, maybe it will be able to drive the AP in all modes; I’m pretty sure it can with the King APs, not sure about Century. I’m sure the shop will be able to take back the G5s and bill you for the more expensive stuff. But then you’re close to GFC-500 pricing, and definitely close to Aspen E5+EA100…

Back to Aspen I guess… Not that bad of an idea…

ah this really sucks.

That’s why you want to get rid of the vacuum system…
The GI-275 (which I suggested above) turns out to be as useless (as @Arne pointed out) for an older Century AP as the G5 for the King stuff, unfortunately. It will only do heading and not attitude.
Given time, perhaps the AV-30 will fill a void, or, just maybe, Dynon (but at a much higher cost, and possibly not in EASA planes).
But seriously, price out an Aspen E5, it recently got a nice software upgrade and does a real HSI representation.
What is the current attitude source for the Century AP?

What is the current attitude source for the Century AP?The vacuum-driven AI.
KI256 / KG258?
This may not be the desired answer but I’ve been flying behind vac pumps and KI256s for 18 years and it really isn’t a big fish to fry. I’ve never had a vac pump fail (I change them as soon as the vacuum falls below the green arc) and I have a spare KI256 and change then over. They come up on US Ebay rgularly and cheaply.
I would spend money on a more flashy navigator (IFD or GTN), TAS…
