Joining the ILS for 03 Fort Nelson
Basically, what's happening here is the FMS is taking us to OBTAM, an initial approach fix on the LOC for the ILS runway 03 in Fort Nelson. At OBTAM, the Localizer (the double dashed blue arrow there) will become the active NAV source. The Autopilot will turn to follow it and we're established on the ILS. I love watching it work.
