Omnidirectional & AP

[jojo]

I try to use AP radial capture with TACAN.

My goal is to be aligned for ILS capture.

The ILS axis is 225°M, set on omnidirectional control box on TACAN position.

I'm flying 285°M, AP + ALT green, "R" armed. 1500ft, my heading would intercept ILS axis at 10Nm, so I have turning room before intercepting the glide around 5Nm.

But the AP is turning too soon or too hard. I end up straight on TACAN at 230° (and off ILS axis).

But flying out of airfield, converging 120° for radial 180° (outbound), it's working.

I don't see any major issue. Can you provide a very short trk recorded in Caucasus, or a detailed description? Txs!

To make it short:

- I set radial 225°/ TACAN selection on omni panel.

- flying 285° (inside of 10Nm), AP + ALT green, “R” mode armed.

- when turning for alignment, the AP settles on heading 230° to TACAN (instead of 225°).

True vs magnetic heading bug?

Doing radio navigation, I was doing everything in magnetic heading and the IDN was set to magnetic North.

Unable to reproduce it, I tried it several times, when you reported it and today again, with the exact description that you provided. This means I'd need a trk, a short one recorded in Caucasus, as I said in my previous post.
