[CA] SPX30 Doing Poorly in Track Mode

[DSanduril]

The problem (from our perspective) is the severity of the turns used to maintain that corridor. If the SPX made turns of 5 degrees or thereabouts it could easily maintain an XTE of +/- 0.01 nm. That's what we currently do in Auto mode, manually adjusting course, usually only one or two degrees and we are able to maintain a very small XTE. It just takes a lot of attention.

If we switch to Track mode the turns become so severe that the corridor actually gets much wider, usually 0.05 or 0.06 sometimes up to 0.10 nm XTE because it takes so long to make the turn, get to the new heading, correct, etc...

We'll give it a try again at Response = 1 to see if that helps reduce the turn amount. If not, is there any other adjustment to reduce/limit the turn allowed in Track mode?

There is rudder reference transducer fitted and working properly, and as noted the AP performs quite well in all other modes.
