400a autopilot to Century Non-slaved HSI

[WebMaster]

Hmmmm. I have a slaved HSI. My autopilot is the 400, not A. It has a switch, for heading or approach. Approach works off the HSI, and heading works off the old DG. I remember flying it, tracking a VOR, and it will track a VOR. We were several miles away, so it wandered a bit, but we definitely can track a VOR, off the HSI. I think it will also fly the glidescope.
