He who ironically no longer flies an AA5B
Question first: Let's say I get my old Century IIB hooked up a G5 DG/HSI such that it is providing heading info to the autopilot in quasi-GPSS mode. Let's say I'm flying along on GPSS and then get vectored to shoot an ILS approach and ILS is on a *separate* indicator (i.e. a completely separate Nav/Comm than what is hooked up to the G5), is there a way to "switch" where the heading input is coming from, so that I can switch the heading input from the G5 to the NAV (ILS) and get the autopilot track down the ILS too?
Background:
Alright everyone, thanks for your patience, I'm finally figuring out how to repair and improve my panel... but I gots one more question!
My situation is that I have a dead attitude indicator and a Century IIB autopilot. I was going to replace the AI with a G5 (dual G5s actually was the original idea). However, it took some digging to confirm, but it turns out that "attitude based" autopilots like mine need input from the attitude indicator, and the G5 AI won't provide it.
I briefly went down the path of considering dual G5s and a new GFC500, but when the quotes came in between $30k and $50k, I got real and realized that's not going to happen.
Where I'm at right now is I think I'll fix the existing AI and keep my Century IIB. I'm tempted to put the G5 in for the HSI/DG anyway for a couple of reasons, one of which is that it will drive the *heading* portion of the autopilot (not attitude - that will still come from my old AI), and my old autopilot will get, essentially, GPSS functionality. Pretty cool, right?
So here's the question: let's say I get my Century IIB hooked up to the G5 DG/HSI and am flying along using GPSS, but then I get vectored to fly a ILS and my ILS is on a *separate* indicator (i.e. a completely separate Nav/Comm than what is hooked up to the G5), is there a way to "switch" where the heading input is coming from, so that I can switch the heading input from the G5 to the NAV (ILS) and get the autopilot track down the ILS too?
