I tested again today (BIRK, rwy 19, ILS Z selected)
Took off from BIRK, directly to IAF on the FMS. Nav source on take-off were FMS1 & FMS2.
I expected
- the localizer frequency selected automatically - but it never happend. So I tuned the loc frequency manually in VOR 1 & 2
- the dashed blue line when getting close to the ILS beam - but it never came
- after turning based on the FMS onto the runway heading, the system still didn't automatically switch to the ILS - but manually selecting the NAV source did work well this time
The FMS is capable to automatically pre-select the localiser frequency and switch over to the ILS, isn't it?
