GPSS with 400A Autopilot

[LostKiwi]

I did see that table on G3 but I wasn't sure how to interpret it. I noticed it says 300 IFCS / 400 IFCS / 800 IFCS, which is like the autopilot that the 337H came out with, right? the one with the FD on the dash and all the buttons?

Then in the "notes" column it references the 400A. So that CA530FD computer (or an aftermarket version thereof) is the dealie-oh we need?

I have a Bendix KI525A HSI, which is coupled into the autopilot. I don't know if I have the Bendix KA57 autopilot convertor, or if I have a Cessna one, or an aftermarket one. I'll have to look.

Then I've got a switch that I can flick to choose if the HSI or the bug on the DG drives the autopilot... No idea what convertors that does or doesn't tie into.
Avionics issues hurt my head.





Cessna fitted 400A's into damn near everything at one point. The 430 has to be one of the most widely produced GPS's of all time. Surely we aren't the first folk to go down this road.

How are you equipped currently?
