I've recently installed the ARINC module to allow the 4500s screen to command the autopilot (Vizion 385). I do not have an IFR navigator, so I just use the 4500 internal flightplan. I'm learning how to best utilize this combo, and one odd thing I've noticed is that the course intercept angle when selecting L:NAV mode is very aggressive; I was expecting 30* or so, but I've seen more like 80*. Is there a setting somewhere I can tweak to adjust this? I've taken to intercepting a course manually, or in L:HDG mode, and only switching to L:NAV after the CDI centers, or hitting "D-> / GOTO / YES" to redraw from the current position if airspace allows.
