Is this the same bug I see in the TBM930 on the G3000 - where it most times just fails to turn onto the localiser, even when correctly set up and the arrival is flown correctly?
The workaround for me is to cycle the NAV selector (on the TBM it’s from VOR1 to VOR2 to FMS and back to the active VOR1 - haven’t checked the G1000) and it is important to do this AFTER the localiser becomes active and the APR mode is selected.
Then it finds the localiser every time.
It’s been like this for ages in the G3000, reported many times since release, and still never fixed.
I don’t understand what other people are doing when they are flying that they don’t also report this issue. It can’t just be me as it’s survived many updates. This is the first time I have seen anyone else report it.
Let me know it this workaround help you.
Obviously it’s not a solution and this needs fixed. It’s very flakey at present, and I have almost hit mountains in foggy landings such as Interlaken due to the bug.
