ILS LOC course not set automatically when using UNS-1

[Puukka]

Hi 

First of all thanks a lot for this nice plane! I only have one question:

When using the UNS-1 and on final, I switch from FMS to NAV Mode at the EHSI Display Controller.

Regulary with this kind of setup I expect that since the ILS runway is programmed at the UNS-1 and the NAV 1 frequency is set properly, that the ILS LOC course is set automatically.

Do I miss something, or is it , that I have to use HDG mode for dialing the ILS course manually?

Thanks and regards, Herbert

No, the UNS doesn’t set the NAV1 course. It doesn’t IRL either, it’s just not wired this way with this avionics suite.

not sure what you mean by “dial it using HDG” — you’d match the heading but with your current heading, then switch the AP mode to HDG. Then change navigation sources to NAV1, set the ILS/LOC front course using the CRS1 knob, then follow ATC instructions u til you can arm NAV or APPR on the autopilot.

Thanks a lot for the information! Yes, sorry, I meant it that way, you’ve been discribing, setting the ILS course during active heading mode.
